Abstract
Background The jackling position within rugby has not been previously described as a mechanism for proximal hamstring injuries. Hypothesis Acute surgical repair of proximal hamstring avulsion injuries sustained from the jackling contact position enables a return to a previous level of sporting activity with low risk of recurrence. Study Design Case series; Level of evidence, 4. Methods This study included 54 professional rugby players (mean age, 26 ± 4.8 years) who underwent acute primary surgical repair of complete, proximal hamstring avulsion injuries. The mean follow-up time was 17 months (range, 12-24 months). Mean isometric hamstring strength and function testing was performed at 3 months and 1 year after repair. Results Of the 54 players, 51 (94.4%) returned to their preinjury level of sporting activity. The mean time from surgical repair to full sporting activity was 7 months (range, 4-12 months). No patients had recurrence of the primary injury. At 1 year postoperatively, patients had significantly restored mean isometric hamstring muscle strength when compared with the uninjured leg at 0° (98.4% ± 2.8%), 15° (95.9% ± 2.9%), and 45° (92.9% ± 4.1%); improved Lower Extremity Functional Score (78.0 ± 2.0); and improved Marx activity rating score (14.3 ± 1.5) (P < .001 for all). Conclusion Acute surgical repair of proximal hamstring avulsion injuries caused by the contact jackling position produced a high return to preinjury level of sporting activity, increased muscle strength, and improved functional outcome scores, with a low risk of recurrence at short-term follow-up.

Magnetic resonance imaging should be the first-line imaging modality for investigating suspected proximal hamstring avulsion injuries. Knee Surg Sports Traumatol Arthrosc 2024. [PMID: 38769849 DOI: 10.1002/ksa.12258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 04/28/2024] [Accepted: 05/02/2024] [Indexed: 05/22/2024]
Abstract
PURPOSE The purpose of the study was to evaluate how the initial diagnostic tool used-specifically ultrasound (US) or magnetic resonance imaging (MRI)-for diagnosing proximal hamstring avulsion injury affects the delay before surgery and, secondarily, the outcomes of these injuries. METHODS This was a retrospective analysis of prospectively collected data (2012-2020). It targeted patients primarily treated for proximal hamstring avulsion injury. It included all patients with a preoperative US and/or MRI. Patients were divided into two groups based on the initial diagnostic tool used (US-first vs. MRI-first groups). The primary outcomes measure was the time from initial injury to surgical intervention (surgical delay). The secondary outcomes were the Parisien Hamstring Avulsion Score, as well as the activity level as measured by the University of California, Los Angeles (UCLA) Activity Scale and Tegner Activity Scale. RESULTS The analysis included 392 patients with a mean age of 43.8 ± 13.6 years for the MRI-first group and 47.6 ± 12.0 years for US-first group. Patients in the MRI-first group had a significantly shorter median time from injury to surgery of 20.0 days (interquartile range [IQR]: 11.0-61.0) compared to 30 days (IQR: 18-74) in the US-first group. At the final follow-up (4.2 ± 2.2 years for the MRI-first group and 5.1 ± 1.9 years for the US-first group), the MRI-first group had significantly higher mean Tegner Activity Scale and UCLA scores than the US-first group: The Tegner Activity Scale was median 5 (IQR: 3-7) for the MRI-first group versus median 4 (IQR: 2-6) for the US-first group (p < 0.05). The UCLA scores were 7.9 ± 2.4 for the MRI-first group compared to 7.3 ± 2.4 for the US-first group (p < 0.05). This difference was more pronounced when comparing the MRI-first group with the patient-false negative initial ultrasound. No difference was found regarding the Parisien Hamstring Avulsion Score. CONCLUSION MRI as the initial diagnostic tool for proximal hamstring avulsion injury is associated with a shorter time to surgery and better postoperative outcomes in Tegner Activity Scale and UCLA scores, compared to US. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Despite the prevalence of proximal hamstring avulsion injuries (PHAIs), the understanding of rerupture risk factors and the influence of injury chronicity on these rates remain limited. PURPOSE To investigate the rerupture rate after PHAI repair and identify its associated risk factors and the optimal time to primary surgery. STUDY DESIGN Case-control study; Level of evidence, 3. METHOD This is a retrospective analysis of prospectively collected data from the French Proximal Hamstring Avulsion Surgery Cohort Study targeting patients surgically treated for PHAI between 2002 and 2022. The primary outcome measure of this study was the rerupture rate of PHAI repair. The secondary outcome measures included the assessment of the potential risk factors for rerupture as well as the investigation of the incidence rate of rerupture for 100 person-years depending on various injury-surgery delay definitions. RESULTS This study analyzed 740 patients with a mean age of 45.9 years (SD, 13.6 years) and followed up for a mean of 4.9 years (SD, 3.9 years). The rerupture rate was 4.59% (34/740). Most reruptures (75%) occurred within the first 6 months after surgery (median, 88.5 days; interquartile range, 39.5-182 days), and 74% were atraumatic. Univariate analysis identified potential risk factors: longer initial surgery delay (hazard ratio [HR], 1.03; 95% CI, 1.01-1.04; P = .04) and initial complete ruptures (HR, 4.47; 95% CI, 1.07-18.7; P = .04). Receiver operating characteristic curve analysis found the optimal injury-surgery delay cutoff predicting rerupture to be 32 days (area under the curve, 0.62; 95% CI, 0.53-0.71). The relative Youden index was calculated at 0.24, corresponding to a sensitivity of 65% and a specificity of 59%. Surpassing this cutoff showed the highest HR (2.56), narrowest 95% CI (1.27-5.17), and highest incidence of rerupture (1.42 per 100 person-years) (P = .01). In the multivariate analysis, an injury-surgery delay of >32 days (HR, 2.5; 95% CI, 1.24-5.06; P = .01) and initial complete ruptures (HR, 4.33; 95% CI, 1.04-18.08; P = .04) emerged as significant risk factors for rerupture. CONCLUSION This study found a 4.59% rerupture risk after PHAI repair. Most reruptures (75%) occurred within the first 6 months after surgery. Risk factors for rerupture included chronicity and initial complete injury. The optimal threshold for chronicity of PHAI lesions, based on rerupture rate, was marked by an injury-surgery delay of >32 days.

Abstract
Purpose To evaluate patient-reported outcomes and risk for rerupture after surgical treatment of proximal hamstring tendon ruptures using all-suture anchors and a unique postoperative bracing strategy. Methods A retrospective review of a prospectively collected database was conducted of patients undergoing proximal hamstring repair or reconstruction from 2020 to 2022 at a tertiary, academic institution. Patients were included if they reached minimum 1-year follow-up and completed postoperative patient-reported outcomes. The surgical protocol for proximal hamstring repairs included all-suture anchors placed either in an open or endoscopic fashion in the ischial tuberosity. After surgery, all patients underwent an accelerated rehabilitation protocol, including 6 weeks touchdown weight-bearing in a hinged knee brace locked in extension for ambulation, allowing passive knee flexion to 90° while seated. Descriptive statistics were used to analyze the data. Results Twenty-one patients were included (mean age 50.4 ± 9.5 years, body mass index 24.4 ± 3.5, 66.7% female). Lower Extremity Functional Scale score achieved postoperatively was 74.2 ± 7.5 (out of 80). Patients had minimal pain (mean visual analog scale pain score of 0.9 ± 1.2). 61.9% of patients were able to return to the same level of activity after based on Tegner score by 1 year. Postoperative Single Assessment Numeric Evaluation activity of daily living was 94.3 ± 8.3, and Single Assessment Numeric Evaluation Sports was 82.3 ± 19.0. Mean Short Form Survey (SF-12) postoperative scores were 51.6 ± 6.8 for SF-12 Physical Component Score and 53.9 ± 9.7 for Mental Component Score. 95.2% (20 of 21) patients were satisfied with their outcome. There were no reruptures, infections, or reoperations. One patient of 21 (4.8%) incurred a postoperative deep venous thrombosis, which was treated with therapeutic anticoagulation for 3 months. Conclusions All-suture anchors for proximal hamstring repair with a unique accelerated postoperative rehabilitation and bracing protocol result in good outcomes and patient satisfaction with minimal risk of complications. Level of Evidence Level IV, case series, therapeutic.

Abstract
BACKGROUND No validated score is available for the prediction of return to sport (RTS) after proximal hamstring avulsion (PHA) surgery. PURPOSE To validate a new assessment tool for patients after PHA surgery: the Parisian Hamstring Avulsion Score (PHAS). STUDY DESIGN Cohort study (Diagnosis); Level of evidence, 3. METHODS All patients at our clinic who had surgery for PHA between January 2015 and March 2018 were included in this study. A suspected clinical diagnosis of PHA was confirmed by magnetic resonance imaging. PHA was repaired by surgical reinsertion with suture anchors. Minimum postoperative follow-up was 2 years, and the PHAS, University of California, Los Angeles (UCLA), score, and Tegner score were used. The PHAS is a patient-reported outcome measure, evaluating the effect of PHA injury with 9 items. It was validated by calculating its psychometric properties, and then correlation analysis was performed to determine the relationship between the PHAS, UCLA score, and Tegner score. Cutoff values for the prediction of RTS were determined. RESULTS A prospective case series study was performed. A total of 156 patients were included. Median age (first quartile; third quartile) was 54.2 years (44.7 years; 61.3 years), and the mean ± SD time of the final follow-up was 69 ± 11.6 months. Two years after surgery, 66.7% (n = 104) of patients were able to RTS. A strong correlation was noted between all 3 scores at 1 year postoperatively. Overall internal consistency was high, with a Cronbach alpha coefficient of 0.86. The intraclass correlation coefficient was 0.96, showing excellent reliability. The minimal detectable change was 12.9. No patients reached the maximum score at 2 years. Analysis of the receiver operating characteristic curves of the 3 scores at postoperative 9 months in relation to the RTS at 1 and 2 years showed area under the curve values of >0.7, indicating significant discriminant capacity for the RTS. A PHAS cutoff value of 86 at 9 months for the prediction of RTS at postoperative 1 year had a sensitivity of 65.6% (95% CI, 53.7%-77.5%) and a specificity of 81.4% (95% CI, 69.8%-93%). CONCLUSION PHAS is a valid and reliable tool for follow-up after PHA surgery. It also offers a simple way to predict RTS.

Association Between Proximal Hamstring Tear Characteristics and Achievement of Clinically Significant Outcomes After Endoscopic and Open Repair at Minimum 2-Year Follow-up. Am J Sports Med 2024; 52:390-400.

Abstract
BACKGROUND The effect of preoperative tear characteristics and the relative efficacy of open versus endoscopic surgical techniques have not been elucidated for the surgical treatment of proximal hamstring tendon injuries. PURPOSE (1) To report on achievement rates of clinically significant outcomes at a minimum 2-year follow-up for multiple patient-reported outcomes (PROs) after surgical treatment of proximal hamstring injuries, stratified according to severity of proximal hamstring injury, and (2) to compare clinical outcomes associated with endoscopic versus open surgical repair for a subset of similarly classified tears. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A single-surgeon clinical registry was queried for patients who underwent surgical repair for proximal hamstring ruptures between January 2012 and March 2021. Injuries were classified by magnetic resonance imaging as follows: grade 1, incomplete tear with the involvement of 1 or 2 tendons; grade 2, complete tear with the involvement of 3 tendons and ≤2-cm retraction; and grade 3, complete tear with the involvement of 3 tendons and >2-cm retraction. The Patient Acceptable Symptom State (PASS) for multiple PROs was calculated and compared among injury grades and between surgical techniques. RESULTS Among 75 patients with a mean follow-up of 30.5 ± 5.1 months, 20 had grade 1 tears, 24 had grade 2 tears, and 31 had grade 3 tears. Favorable 2-year postoperative PROs were demonstrated by each grade for all measured PROs. Patients with grade 3 tears were noted to have significantly lower rates of 2-year PASS achievement for the Hip Outcome Score-Activities of Daily Living (HOS-ADL) and Hip Outcome Score-Sports Specific (HOS-SS) scales (P≤ .032). Among grade 2 tears, patients treated endoscopically demonstrated significantly greater HOS-SS (endoscopic, 91.7%; open, 58.3%; P = .045) and Patient-Reported Outcomes Measurement Information System for Physical Function (endoscopic, 80.0%; open, 50.0%; P = .033) PASS achievement rates compared with those treated with the open technique. Complication rates were highest in patients with grade 3 tears (45.2%, P = .043). CONCLUSION Surgical repair of proximal hamstring tendon tears with varying extents of tendon retraction resulted in high rates of achieving PASS at the 2-year follow-up. Among complete tears with <2 cm of retraction, endoscopic repairs exhibited equal or higher rates of achieving PASS compared with open repairs across multiple PROs at 2 years postoperatively. However, patients with complete tears and retraction >2 cm achieved lower rates of PASS on the HOS-ADL and HOS-SS scales and had a higher rate of complications.

Abstract
Background Traditionally, postoperative rehabilitation protocols after proximal hamstring repair (PHR) for avulsion of the proximal hamstring tendon from its ischial insertion recommend bracing the hip and/or knee to protect the fixation. However, because of the cumbersome nature of these orthoses, recent studies have investigated outcomes in patients with postoperative protocols that do not include any form of postoperative bracing. Purpose To synthesize the current body of evidence concerning bracing versus nonbracing postoperative management of PHR. Study Design Systematic review; level of evidence, 4. Methods Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we conducted a thorough search of the PubMed/Medline, Cochrane, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Embase (OVID) databases on March 24, 2023. We analyzed complication rates, reoperation rates, patient satisfaction, return to sport, and patient-reported outcomes of studies that used postoperative bracing versus studies that used no postoperative bracing after PHR with at least 12 months of follow-up. A total of 308 articles were identified after initial search. Results In total, 25 studies were included in this review: 18 studies (905 patients) on bracing and 7 studies (291 patients) on nonbracing after PHR. The overall complication rate in the braced patients was found to be 10.9%, compared with 12.7% in nonbraced patients. The rate of reoperation due to retear of the proximal hamstring was found to be 0.05% in braced patients and 3.1% in nonbraced patients. Patient-reported outcome measures were found to be higher at the final follow-up in braced versus nonbraced patients, and patient satisfaction was found to be 94.7% in braced studies compared with 88.9% in nonbraced studies. The rate of 12-month return to sport in athletic patients was 88.4% with bracing and 82.7% without bracing. Conclusion The findings of this review demonstrated lower complication and reoperation rates, higher patient-reported outcome scores, higher patient satisfaction, and a higher rate of return to sport in braced patients compared with nonbraced patients.

Abstract
Purpose An MRI-based scoring tool assessing surgical repair after proximal hamstring avulsions may provide benefit in the context of research, while serial post-operative MRI will provide insight of what to expect in the clinical context of early re-injury requiring imaging. This study developed and assessed the reliability of a Proximal Hamstring Objective Magnetic Resonance Imaging Score (PHOMRIS), further assessing MRI-based repair status and its correlation with patient-reported outcome. Methods 15 patients that underwent proximal hamstring surgical repair underwent MRI and clinical review pre-operatively and at 3-, 6- and 12-months. Clinical scores included the Lower Extremity Functional Scale (LEFS), the Perth Hamstring Assessment Tool (PHAT) and Tegner Activity Scale (TAS). The MRI-based tool assessed the conjoint (semitendinosus & biceps femoris) and semimembranosus insertion components based on bone-tendon healing, signal and retraction. Inter- and intra-observer reliability of the tool was assessed. Results Inter-observer reliability indicated a strong correlation for the semimembranosus (rho = 0.827, p < 0.0001) and conjoint (rho = 0.851, p < 0.0001) components. Intra-observer reliability indicated a strong correlation for the semimembranosus (rho = 0.852, p < 0.0001) and conjoint (rho = 0.996, p < 0.0001) components. All clinical scores and the semimembranosus hamstrings component MRI score significantly improved (p < 0.05) over time, though the conjoint component did not (p = 0.219). At 12 months, a higher LEFS was significantly associated with a better semimembranosus MRI score (r = -0.57, p = 0.042), though no other significant correlations (p > 0.05) were observed between clinical and MRI measures. Conclusions Excellent reliability was observed for the MRI-based scoring tool, which may prove useful in both a research and clinical setting.

Abstract
Symptomatic proximal hamstring tendon tears are typically repaired surgically, with open incision and knot-tying technique. An endoscopic, knotless, suture-bridge repair technique is presented. Potential advantages include knotless simplicity, compression over a broad zone to improve tendon-bone healing, and decreased pain secondary to elimination of knots and the open incision and approach.

Abstract
Background Although several complications of proximal hamstring tendon ruptures have been reported in the literature, few studies have comprehensively analyzed the complication profile of proximal hamstring tendon repair. Purpose To identify the overall rate of complications following proximal hamstring tendon repair and to differentiate these complications into categories. Study Design Systematic review; Level of evidence, 4. Methods Included in this review were studies that examined surgical repair of proximal hamstring tendon ruptures; all studies were in English and had an evidence level of 4 or higher. No restrictions were made regarding publication date or methodological quality. Data regarding complications were extracted to calculate the overall complication rate as well as the rate of major and minor complications. A quantitative data synthesis was conducted using the chi-square test to compare the proportion of patients who experienced complications with the endoscopic versus open approach. Results A total of 43 articles including 2833 proximal hamstring tendon repairs were identified. The overall postoperative complication rate was 15.3% (n = 433). The rate of major complications was 4.6%, including a 1.7% rate of sciatic nerve injury, 0.8% rate of venous thromboembolism, 0.8% reoperation rate, 0.8% rerupture rate, and 0.4% rate of deep infection. Minor complications included a 2.4% rate of posterior femoral cutaneous nerve injury, 2.3% rate of persistent hamstring myopathy, 2.2% rate of persistent sitting pain, 1.8% rate of peri-incisional numbness, 1.1% rate of superficial infection, and 0.8% rate of hematoma/seroma. Conclusion Proximal hamstring tendon repair is associated with an overall complication rate of 15.3%, including a 4.6% rate of major complications.

Abstract
Snapping proximal hamstring is an uncommon phenomenon, with few case reports documenting surgical treatment. The purpose of this study is to report snapping resolution, minimum 2-year post-operative patient-reported outcome (PRO), satisfaction scores and complications from patients who underwent surgical release of the conjoint tendon from the sacrotuberous ligament with reattachment to the ischial tuberosity. Prospectively collected data from two institutional databases were retrospectively reviewed for patients who underwent hamstring repair for partial- or full-thickness tears. Patients were included if they demonstrated 'snapping proximal hamstrings' on preoperative physical examination, including ultrasound confirmation, and repair subsequently performed. Patients were excluded if they had reconstruction of the proximal hamstring tendon or claimed worker's compensation. With a total of 20 patients (15 females and 5 males), successful resolution of snapping was reported in 100% of the cohort. For patients with pre- and post-surgical lower-extremity functional scores (LEFS), post-surgical LEFS were significantly higher than pre-surgical LEFS (pre-surgical: 17.0 ± 4.0, post-surgical: 73.6 ± 3.3, P < 0.001). Average post-operative PROs were as follows: International Hip Outcome Tool-12, 92.3 ± 8.3; modified Harris Hip Score, 93.2 ± 7.8; Non-arthritic Hip Score, 92.5 ± 6.8; Hip Outcome Score-Sports Specific Subscale, 94.4 ± 6.7; LEFS, 73.9 ± 3.4; and median visual analog scale of 0 with an interquartile range of 0-1. Patient satisfaction was 'very satisfied' in 19 (95%) patients and 'satisfied' in 1 (5%) patient. At a minimum 2-year follow-up, patients who underwent surgical treatment for chronic snapping of the proximal hamstrings demonstrated complete resolution of painful posterior snapping, reported high PROs and satisfaction, and had no reported post-operative complications.

Abstract
PURPOSE OF REVIEW To assess the current literature surrounding the treatment and rehabilitation strategies surrounding proximal hamstring rupture injuries, along with comparative return to sport and patient-reported outcomes. RECENT FINDINGS A high degree of variability exists in protective and rehabilitation strategies after both operative and non-operative proximal hamstring rupture management. Acceptable outcomes after both operative and non-operative management have been observed but may vary greatly with injury chronicity, severity, and surgical technique. The high complication rates observed after surgical treatment, along with poor functional outcomes that may occur in the setting of non-operative treatment or delayed surgery, highlight the importance of early injury evaluation and careful patient selection. Further high-quality research elucidating clearer indications for early operative management and an optimized and standardized rehabilitation protocols may improve outcomes and return to sport experience and metrics for individuals sustaining proximal hamstring ruptures.

Modified surgical anchor refixation in older patients with acute proximal hamstring rupture: clinical outcome, patient satisfaction and muscle strength. Arch Orthop Trauma Surg 2023:10.1007/s00402-022-04752-3.

Abstract
INTRODUCTION After conventional surgical refixation of the hamstrings after proximal hamstring rupture, patients frequently experience pain while sitting and deficits in hamstring muscle strength of the operated side. To improve these outcomes, we have modified the surgical anchor placement and have carried out a thorough follow-up examination. MATERIALS AND METHODS Thirteen older patients (8 female, 5 males) with a median age of 64.2 (range, 52.1-80.4) years were surgically treated for acute proximal hamstring rupture using modified anchor placement and participated in a follow-up assessment at a median of 46.2 (11.2-75.0) months after surgery. Patients completed the Perth Hamstring Assessment Tool (PHAT), quality of life questionnaire (EQ-5D-5L) and the Lower Extremity Functional Scale (LEFS), and rated their satisfaction level on a scale from 0 to 100%. Local tenderness on the ischial tuberosity and maximum passive hip flexion were measured on both limbs. Maximum isokinetic knee flexor muscle strength was measured bilaterally using a dynamometer. RESULTS The median (range) PHAT, EQ-5D-5L and LEFS score were 78.8/100 (54.6-99.8), 0.94/1 (0.83-1) and 88.75/100 (61.25-100). The median satisfaction was 100% (90-100%). Only one patient felt discomfort when the ischial tuberosity was palpated. Neither maximum passive hip flexion nor maximum isokinetic flexor muscle strength differed between the operated and non-operated side (P > 0.58). Clinical scores did not correlate with the leg symmetry index of knee flexor muscle strength (Spearman's rho < 0.448, P > 0.125). There were no tendon re-ruptures, or postoperative sciatic radiculopathy, at the time of follow-up. CONCLUSIONS The modified extra-anatomical anchor placement resulted in good clinical and functional outcome of surgical repair of acute proximal hamstring rupture. Especially the absence of postoperative pain while sitting and the comparable muscle strength to the contralateral side is promising.

Abstract
Hamstring injuries are among the most common muscle injuries. They have been reported in many different sports, such as running, soccer, track and field, rugby, and waterskiing. However, they are also present among the general population. Most hamstring injuries are mild strains, but also moderate and severe injuries occur. Hamstring injuries usually occur in rapid movements involving eccentric demands of the posterior thigh. Sprinting has been found to mainly affect the isolated proximal biceps femoris, whereas stretching-type injuries most often involve an isolated proximal injury of the semimembranosus muscle. The main cause of severe 2- or 3-tendon avulsion is a rapid forceful hip flexion with the ipsilateral knee extended. Most hamstring injuries are treated non-surgically with good results. However, there are also clear indications for surgical treatment, such as severe 2- or 3-tendon avulsions. In athletes, more aggressive recommendations concerning surgical treatment can be found. For a professional athlete, a proximal isolated tendon avulsion with clear retraction should be treated operatively regardless of the injured tendon. Surgical treatment has been found to have good results in severe injuries, especially if the avulsion injury is repaired in acute phase. In chronic hamstring injuries and recurring ruptures, the anatomical apposition of the retracted muscles is more difficult to be achieved. This review article analyses the outcomes of surgical treatment of hamstring ruptures. The present study confirms the previous knowledge that surgical treatment of hamstring tendon injuries causes good results with high satisfaction rates, both in complete and partial avulsions. Early surgical repair leads to better functional results with lower complication rates, especially in complete avulsions.KEY MESSAGEsSurgical treatment of hamstring tendon ruptures leads to high satisfaction and return to sport rates.Both complete and partial hamstring tendon ruptures have better results after acute surgical repair, when compared to cases treated surgically later.Athletes with hamstring tendon ruptures should be treated more aggressively with operative methods.

Abstract
Background: Several studies have reported excellent results after surgical repair of proximal hamstring avulsions. However, the effect on these patients of receiving workers’ compensation has not yet been explored. Hypothesis: Workers’ compensation patients undergoing proximal hamstring repair of complete tears will have similar outcomes when compared with a matched control group of non–workers’ compensation patients. Study Design: Cohort study; Level of evidence, 3. Methods: Workers’ compensation patients who underwent complete proximal hamstring avulsion open repair between 2010 and 2019 were identified (WC group). A control group was matched by age (±3 years), sex, and body mass index (BMI; ±3). Demographics and patient-reported outcome measures were compared, including standard and custom Marx activity rating scale (MARS), standard and custom lower extremity functional scale (LEFS), and visual analog scale (VAS) for pain. Rate and time to return to work were recorded. Results: The WC group was composed of 20 patients (8 men, 12 women) with a mean age of 52.3 years and BMI of 32.4. The 20 matched controls (8 men, 12 women) who underwent repair had a mean age of 50.6 years and a mean BMI of 31.2. There was no difference between the groups regarding age (P = .924), sex (P > .999), or BMI (P = .330). The WC group reported similar mean MARS (3.3 vs 5.4; P = .174), custom MARS (87.5 vs 97.0; P = .215), and VAS pain (3.3 vs 3.8; P = .698) scores compared with controls. However, the WC group had significantly lower standard LEFS (69.1 vs 94.1; P < .001) and custom LEFS (62.3 vs 87.9; P < .001) scores, returned to work at a lower rate (70.0% vs 94.1%; P = .039), and required more time to return to work after repair (4.3 vs 3.5 months; P = .029) compared with controls. Conclusion: Workers’ compensation patients who underwent open proximal hamstring repair for complete avulsions experienced inferior patient-reported outcomes, required more time to return to work, and returned to work at a lower rate than a matched control group.

Abstract
Background There is controversy regarding which patient-reported outcome measures (PROMs) should be used for proximal hamstring tendon injuries. Hypothesis It was hypothesized that (1) most (>50%) of the questions on the 13 most common PROMs for proximal hamstring injuries would demonstrate extensive overlap in the health domains and question categories and (2) each of the PROMs would contain a variable distribution of questions within each health domain. Study Design Systematic review. Methods We conducted a literature review through PubMed, Scopus, and CINAHL and identified the 13 most common PROMs for proximal hamstring injuries: Lower Extremity Functional Scale (LEFS), Marx activity rating scale (MARS), 12-item Short Form Survey (SF-12), Tegner activity scale (TAS), Single Assessment Numeric Evaluation (SANE), Perth Hamstring Assessment Tool (PHAT), Proximal Hamstring Injury Questionnaire (PHIQ), modified Harris Hip Score (mHHS), University of California, Los Angeles activity score (UCLA), International Hip Outcome Tool (iHOT-12), Hip Outcome Score (HOS), Sydney Hamstring Origin Rupture Evaluation (SHORE), and Non-Arthritic Hip Score (NAHS). All PROM questions were sorted into 5 health domains (pain, symptoms, activities of daily living, sports, and mindset) and further divided into question categories if they referred to similar tasks or aspects of health. Questions in the same health domain and question category were considered overlapping, and those within a health domain that did not fit into a question category were considered unique. For each PROM, we analyzed the distribution of questions within particular health domains and question categories as well as the amount of overlapping and unique questions. Results Of the 165 questions evaluated, 116 (70.3%) were overlapping, and 49 (29.7%) were unique. The SF-12 contained the most unique questions (9/12 [75.0%]). The MARS, TAS, SANE, and UCLA had 0 unique questions. The PHIQ and iHOT-12 contained questions in all 5 health domains. The PHAT, SHORE, and NAHS contained questions in every health domain except mindset. The LEFS, MARS, SF-12, TAS, mHHS, SANE, UCLA, and HOS contained questions in ≤3 health domains. Conclusion The evaluated PROMs had a high degree of overlapping questions (≥50%) and demonstrated a statistically significant variance in the distribution of questions within each health domain.

Abstract
Purpose The purpose of our study is to identify the location of the posterior femoral cutaneous nerve (PFCN) and its branches in relation to the proximal hamstring tendon. Methods Fifteen lower torso human cadaveric specimens were dissected in prone position. Skin and subcutaneous tissues were reflected to expose the gluteal and hamstring musculature. The distance between the ischial tuberosity and lateral border of the hamstring, PFCN, perineal branch of the PFCN, and descending femoral branch of the PFCN was measured with digital calipers. Measurements were repeated three times and averaged. Results The PFCN was 30.5 ± 11.4 mm lateral to the central tip of the ischial tuberosity (range: 15.7 to 52.0 mm). The average longitudinal distance from the tip of the ischial tuberosity to the point where the perineal branch crossed the hamstrings was 24.1 ± 15.0 mm (range: 9.9 to 52.2 mm). The average longitudinal distance to the point where the descending cutaneous branch crossed the hamstrings was 83.3 ± 21.3 mm (range: 41.3 to 110.3 mm). The PFCN was nearest to the inferior border of the gluteus maximus 45.8 ± 13.6 mm lateral to the ischial tuberosity (range: 13.6 to 62.1 mm). Eleven specimens (73%) had one identifiable perineal branch; four (27%) had two distinct perineal branches. Conclusions The PFCN was in close proximity to the surgical approach used during proximal hamstring repair, with the perineal branch consistently crossing the surgical field transversely. The location of these nerves varied substantially among the specimens tested, with some nerves less than 1 cm from the ischial tuberosity and 27% of specimens with two perineal branches.

Abstract
Aims Avulsion of the proximal hamstring tendon origin can result in significant functional impairment, with surgical re-attachment of the tendons becoming an increasingly recognized treatment. The aim of this study was to assess the outcomes of surgical management of proximal hamstring tendon avulsions, and to compare the results between acute and chronic repairs, as well as between partial and complete injuries. Methods PubMed, CINAHL, SPORTdiscuss, Cochrane Library, EMBASE, and Web of Science were searched. Studies were screened and quality assessed. Results In all, 35 studies (1,530 surgically-repaired hamstrings) were included. Mean age at time of repair was 44.7 years (12 to 78). A total of 846 tears were acute, and 684 were chronic, with 520 tears being defined as partial, and 916 as complete. Overall, 92.6% of patients were satisfied with the outcome of their surgery. Mean Lower Extremity Functional Score was 74.7, and was significantly higher in the partial injury group. Mean postoperative hamstring strength was 87.0% of the uninjured limb, and was higher in the partial group. The return to sport (RTS) rate was 84.5%, averaging at a return of 6.5 months. RTS was quicker in the acute group. Re-rupture rate was 1.2% overall, and was lower in the acute group. Sciatic nerve dysfunction rate was 3.5% overall, and lower in the acute group (p < 0.05 in all cases). Conclusion Surgical treatment results in high satisfaction rates, with good functional outcomes, restoration of muscle strength, and RTS. Partial injuries could expect a higher functional outcome and muscle strength return. Acute repairs result in a quicker RTS with a reduced rate of re-rupture and sciatic nerve dysfunction.

Abstract
CASE Proximal hamstring tendon avulsions are rare injuries that can be successfully treated with surgical intervention. However, there are limited reports on the surgical and postoperative management of patients with bilateral avulsions. We report a 54-year-old male gym teacher with acute bilateral proximal hamstring 3-tendon nonbony avulsions who underwent simultaneous surgical repairs and a unique postoperative rehabilitation course. At 1-year clinical follow-up, the patient demonstrated significant improvements in activity levels and functionality, with no complications. CONCLUSION Bilateral proximal hamstring 3-tendon nonbony avulsions can be successfully treated with a simultaneous surgical repair and a modified postoperative rehabilitation course.

Abstract
OBJECTIVE To prospectively evaluate 1-year clinical and radiological outcomes after operative and non-operative treatment of proximal hamstring tendon avulsions. METHODS Patients with an MRI-confirmed proximal hamstring tendon avulsion were included. Operative or non-operative treatment was selected by a shared decision-making process. The primary outcome was the Perth Hamstring Assessment Tool (PHAT) score. Secondary outcome scores were Proximal Hamstring Injury Questionnaire, EQ-5D-3L, Tegner Activity Scale, return to sports, hamstring flexibility, isometric hamstring strength and MRI findings including proximal continuity. RESULTS Twenty-six operative and 33 non-operative patients with a median age of 51 (IQR: 37-57) and 49 (IQR: 45-56) years were included. Median time between injury and initial visit was 12 (IQR 6-19) days for operative and 21 (IQR 12-48) days for non-operative patients (p=0.004). Baseline PHAT scores were significantly lower in the operative group (32±16 vs 45±17, p=0.003). There was no difference in mean PHAT score between groups at 1 year follow-up (80±19 vs 80±17, p=0.97). Mean PHAT score improved by 47 (95% CI 39 to 55, p<0.001) after operative and 34 (95% CI 27 to 41, p<0.001) after non-operative treatment. There were no relevant differences in secondary clinical outcome measures. Proximal continuity on MRI was present in 20 (95%, 1 recurrence) operative and 14 (52%, no recurrences) non-operative patients (p=0.008). CONCLUSION In a shared decision-making model of care, both operative and non-operative treatment of proximal hamstring tendon avulsions resulted in comparable clinical outcome at 1-year follow-up. Operative patients had lower pretreatment PHAT scores but improved substantially to reach comparable PHAT scores as non-operative patients. We recommend using this shared decision model of care until evidence-based indications in favour of either treatment option are available from high-level clinical trials.

Abstract
Background Although debilitating, proximal hamstring tendon avulsion injuries are rare and often overlooked or misdiagnosed. Consequently, delayed diagnosis and surgical treatment may result in poor outcomes. Studies investigating a correlation between postoperative functional outcomes and this delay in surgical treatment or other concomitant factors in large cohorts have not yet been performed to our knowledge. Purpose/Hypothesis The purpose of this study was to conduct an investigation in a large patient group regarding factors that could influence a patient's functional outcome after hamstring surgery. We hypothesized that this outcome would significantly correlate to the time between trauma and surgery. Study Design Case series; Level of evidence, 4. Methods Patients who received surgical treatment of proximal hamstring tendon avulsion injuries in our institution between the years 2010 and 2020 were asked to complete a validated, injury-specific outcome measurement, the Perth Hamstring Assessment Tool (PHAT; 0-100 points). In addition to calculating these outcomes, we evaluated the association of the obtained results with possible predictive factors such as age, sex, stump retraction shown on magnetic resonance imaging (MRI), and timing and duration of surgery. Results A total of 226 patients (227 operations) were eligible for the study, and 204 cases of hamstring tendon avulsion injury met our inclusion criteria. The return rate for the PHAT questionnaire was 85.3%. The mean PHAT score revealed good results (79.8 ± 19.1). Irrespective of concomitant factors, the scores of male patients were significantly higher compared with those of female patients (83.8 ± 16.9 vs 75.8 ± 20.6 respectively; P = .004). The mean time to surgery was 5.7 weeks after trauma, and more delayed surgery correlated significantly with lower PHAT scores (P = .003; r = -0.228). The mean degree of stump retraction on MRI (5 cm) did not significantly influence PHAT scores (P = .525; r = -0.06). Conclusion Delay of surgery and female sex were disadvantageous in terms of a good functional outcome measure (PHAT score) after hamstring tendon refixation surgery. By contrast, patient age as well as the retraction of the tendon stump on preoperative MRI did not influence PHAT scores in the present study.

Abstract
Muscle injuries of the hamstrings are among the most frequent in football and a main cause for significant time away from training and competition. The purpose of this study was to prospectively evaluate the loss of muscle volume in recreational football players three and six weeks after initial trauma. We hypothesized that significant muscle volume loss occurs within 6 weeks after the initial injury event. Twenty recreational football players (mean-age=25 ± 4years; mean-height=181 ± 8cm; mean-weight=81 ± 10kg) with type3a (minor partial muscle tear) and type3b (moderate partial muscle tear) injuries were included. Muscle volume was determined using established methods for the hamstrings and the quadriceps femoris muscle within 3 days and after 3 and 6 weeks following the initial injury. The injured hamstrings lost 6.5% (mean=64 cm3(95%CI=31-98 cm3), p<0.001), the healthy hamstrings lost 2.1% (mean=21 cm3(3-44 cm3),p=0.096) of muscle volume after six weeks. The quadriceps in the injured leg lost 3.8% (mean=78 cm3(51-104 cm3), p<0.001) and 4.5% (83 cm3 (45-121 cm3), p<0.001) in the healthy leg. Muscle volume loss inversely correlated with activity levels in the healthy leg for the quadriceps (r=0.96 (0.90-0.98); R2=0.92; p<0.001) and the hamstrings (r=0.72 (0.40-0.88); R2=0.51; p<0.001), as well as the quadriceps in the injured leg (r=0.70 (0.37-0.87); R2=0.49; p<0.001), but not the injured hamstrings. Muscle volume ratio of hamstrings to quadriceps in the control limb was 0.52 ± 0.06 and 0.53 ± 0.06 in the injured leg. The rehabilitation period of six weeks did not have a relevant negative or a positive effect on ratios. Significant muscle volume loss in the upper thigh occurs in recreational soccer players within three, and within six weeks after a hamstring injury and lies between 2% and 7%.Highlights This study found that significant muscle volume loss occurs within six weeks after sustaining hamstring muscle group injuries.Additionally, most of the non-professional football players in the present study demonstrated low hamstring-to-quadriceps volume ratios in both the injured, as well as the heathy leg. Low hamstring-to-quadriceps volume ratios may provide an opportunity to focus on muscle hypertrophy strategies to help reduce the risk for muscle imbalances and thus future injury.After three weeks of resting, reduced training activity, compared to the training activity before the injury, seems to be sufficient to preserve 99% of the remaining muscle volume in the quadriceps and as well as the healthy hamstrings. The number of training-minutes correlates statistically significant inversely with the muscle volume lost in a rehabilitation period.

Abstract
BACKGROUND Avulsion injuries of the proximal hamstring muscles are rare but very severe injuries to the dorsal thigh musculature. OBJECTIVE Due to improved diagnostics and experience in treatment, the decision for surgical treatment is becoming more and more frequent. Presentation of the surgical method, follow-up treatment and outcome. MATERIAL AND METHODS Description of the anatomy, origin, diagnostics and treatment of avulsions of the hamstring musculature. RESULTS Due to improvement of knowledge and diagnostics, avulsion injuries of the hamstring muscles are identified more frequently. The rapid expansion of the diagnostics, including magnetic resonance imaging (MRI) is decisive for a better identification of the extent and severity of the injury. Even if the differences in long-term results between surgical and conservative treatment are not significant in the literature, there is a clear improvement in function and resilience after surgical treatment of avulsion injuries of the hamstring muscles. CONCLUSION In view of the poor results of nonsurgical treatment and the clearly positive reports of surgical success, open refixation is recommended for recent proximal hamstring ruptures.

Abstract
BACKGROUND Injuries to the hamstring muscles and tendon complex are among the most frequent muscular injuries with proximal hamstring tendon avulsion being a particularly severe form. The surgical treatment of these injuries is superior to conservative management with respect to patient satisfaction, recovery of muscle strength and function as well as return to sport rates. It is therefore the method of choice. OBJECTIVE Presentation and comparison of the surgical results after treatment with titanium, polyether ether ketone (PEEK) and all suture anchors. MATERIAL AND METHODS A systematic search was carried out in the PubMed medical database and the results are summarized. RESULTS All systems exhibit comparable biomechanical properties regarding elongation and ultimate failure load. Tendon repair with these anchors results in good to excellent clinical outcomes and shows high return to sport and low complication rates. Patient satisfaction after hamstring tendon repair is reported to be over 90% and return to sport rate is 80-100%. The muscle strength recovers to 80-90% in comparison to the contralateral side. CONCLUSION All available anchors systems provide good to excellent clinical outcomes and an explicit advantage for one anchor system could so far not be shown.

Abstract
To evaluate the outcome of a novel, combined endoscopic and mini-open repair (CEMR) of a chronic complete retracted proximal hamstring tendon avulsion (PHA). A retrospective case series of a single-surgeon database for all patients, with a minimum of 1-year follow-up, who underwent CEMR between July 2015 and September 2019 was performed. Patients were evaluated for their functional outcome using the Perth Hamstring Assessment Tool (PHAT). At the latest follow-up, patients were evaluated for their muscle strength, subjective satisfaction and post-operative complications. Twelve patients who underwent endoscopic surgery for chronic PHA were identified, of which seven patients underwent CEMR. After exclusion of one patient from the study due to an open claim for health insurance, six patients (five males) with a mean age of 48 years (range 20-61 years) were evaluated. The mean time from injury to surgery was 12 months (range 2-43 months). At a mean follow-up of 28 months (range 12-55 months), the average PHAT score was 73 (range 70-80). The mean subjective activity level percentage improved from 34 (range 20-50) pre-surgery to 81 (range 75-90) post-surgery. The mean strength of the quadriceps, hamstring at 30°, and hamstring at 90° of the operated leg compared to the uninjured leg did not differ significantly. One patient underwent adhesiolysis 1 year after the index procedure for treatment of subcutaneous adhesions. CEMR is a viable and safe option for the treatment of chronic complete proximal hamstring tears, with good to excellent short-term functional outcome. Level of evidence: IV.

Abstract
Background: Patient-reported outcome measures are important to determine outcomes after
orthopaedic procedures. There is currently no standard for outcome measures
in the evaluation of patient outcomes after proximal hamstring repair. Purpose: To identify and evaluate outcome measures used after proximal hamstring
repair. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed to identify all English-language articles
assessing outcomes after proximal hamstring repair in PubMed, Embase, CINAHL
via EBSCOhost, MEDLINE via OvidSP, and Web of Science between 2000 and 2019.
After duplicates were removed, studies were selected using eligibility
criteria established by the authors. Image reviews, anatomic/histology
studies, literature reviews, surgical technique reports, systematic reviews,
narrative reviews, case studies, and studies with <5 patients were
excluded. Extraction, synthesis, and analysis of outcome measure data were
performed using Microsoft Excel. Quality assessment of included studies was
performed using Methodological Index for Non-Randomized Studies
criteria. Results: After duplicate articles were removed, a total of 304 unique articles were
identified and 27 met the inclusion criteria. The mean number of patients
with proximal hamstring repairs per study was 40. The most frequently
reported outcome measures were return to sport (14/27; 51.9%), custom
survey/questionnaire (13/27; 48.1%), and isokinetic hamstring strength
testing (13/27; 48.1%). Six of the 10 most commonly used outcome measures
were validated and included Lower Extremity Functional Scale, 12-Item Short
Form Health Survey, visual analog scale for pain, Perth Hamstring Assessment
Tool (PHAT), Single Assessment Numeric Evaluation, and Tegner Activity
Scale. Of those, PHAT was the only validated outcome measure designed for
proximal hamstring repair. Conclusion: There is currently no consensus on the best outcome measurements for the
evaluation of patients after proximal hamstring repair. We recommend an
increased commitment to the use of return to sport, isokinetic strength
testing, Lower Extremity Functional Scale, and PHAT when assessing such
injuries. Future studies should aim to define the most reliable methods of
outcome measurement in this patient population through consistent use of
tools that are clinically relevant and important to patients and can easily
be employed in a variety of clinical scenarios.

Abstract
BACKGROUND Injury to the posterior femoral cutaneous nerve (PFCN) produces sitting pain in the buttock, posterior thigh, and/or the ischial tuberosity. The anatomy of the PFCN has not been well described, and just one small cohort of patients has been reported to have resection of the PFCN. METHODS Retrospective review of all patients undergoing resection of the PFCN for sitting pain by the senior author between 2012 and 2019 was performed. Evaluation was done by chart review, intraoperative description of the anatomy of the PFCN, and the outcome of resection of the PFCN with implantation of the proximal nerve into the gluteus muscle. Outcome was determined by direct patient examination, email reports, and telephonic interview. RESULTS Fifty-two patients were included in this study, of which nine were bilateral operative procedures. Thirty-four patients had sufficient follow-up data at a mean of 23 months (3-85 months, range). MRI evidence of hamstring injury was present in 50% of the patients. The classic PFCN anatomy was present in 44% of limbs with the other 56% having a high division permitting branches to the lateral buttock and posterior thigh to be preserved. In patients with bilateral anatomy observations, symmetry was present in 67%. An excellent result (absence of sitting pain, normal activities of daily living [ADL]) was obtained in 53%, a good result (some residual sitting pain with some reduction in ADL), was obtained in 26% and no improvement was observed in 21% of patients. CONCLUSION Sitting pain due to injury to the PFCN can be relieved by the resection of the PFCN with implantation of the proximal end into muscle. Presence of an anatomical variation, a high division of the PFCN, can permit preservation of sensation in the lateral buttock and posterior thigh in the patient whose symptoms involve just the perineum and ischial tuberosity.

Abstract
Proximal hamstring tendon injuries are common among active and athletic populations and exist on a spectrum ranging from proximal tendinopathy to partial tears to complete avulsions. Imaging should include plain radiography as bony avulsions have been observed in skeletally immature patients. Magnetic resonance imaging is diagnostic in the setting of both partial tears and complete tears. A high-intensity (on T2-weighted images), crescent-shaped signal at the tendon-bone interface ("sickle sign") is indicative of a partial-thickness tear of the proximal hamstring tendons. In the setting of complete avulsions, magnetic resonance imaging is also useful in demonstrating the extent of tendon avulsion and quantifying the number of tendons torn. Nonoperative treatment for proximal tendinopathy, acute partial tears, and complete tears with minimal tendon retraction includes activity modification, eccentric stretching and strengthening, and potentially platelet rich plasma injections. Surgical repair should be considered for partial tears refractory to nonoperative management, acute tears with greater than 2 cm of distal retraction, and/or chronic retracted tears. The surgical approach is generally made through a transverse incision within the gluteal crease, which can be extended distally in a "T" configuration in the setting of chronic retracted tears. In the setting of chronic retracted tears, a sciatic nerve neurolysis may be required owing to scarring. Following the surgical procedure, a graduated rehabilitation protocol is commenced with the expectation for a return to full, unrestricted activities by 6 months postoperative, and excellent outcomes can be anticipated. Compared with repair of chronic tears, acute repairs have improved functional outcomes and lower re-tear rates.

Abstract
Proximal hamstring tendon avulsions are a relatively rare type of hamstring injury associated with persistent morbidity, including pain, weakness, and functional limitations. Open or endoscopic surgical repair is the standard treatment for complete tendon avulsions or partial tears that remain symptomatic despite conservative management in relatively young, healthy, and active patients. However, complications known to occur include retearing of the hamstring, infection, nerve injury, inability to return to work or sport, subjective persistent weakness, and subjective persistent pain. In the case of persistent pain where the repair is partially retorn, a careful history, physical examination, and scrutiny of radiologic studies can help guide management. We describe a technique for using revision endoscopy and augmentation with a bovine bioinductive patch in a case of chronic persistently painful partial retear after a proximal hamstring repair.

Abstract
Purpose: Physical activity level is a prognostic variable for patients with injuries. Self-report questionnaires exist to obtain these measures; however, they are not accessible to all populations because of language barriers. Therefore, the purpose of this study was to translate and validate the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) for francophones. Method: We translated the HSS Pedi-FABS using the forward–reverse translation approach and validated it among bilingual adults and an expert panel before administering it to a paediatric population. A repeated-measures crossover design was used: forty-three middle school students, aged 13.1 (SD 0.75) years, were randomly administered either the English or the French questionnaire. Two days later, all participants completed the other version. The translated questionnaire was assessed for its convergent validity (Spearman’s r correlation coefficients [ rs]), internal consistency (Cronbach’s α), and reliability (standard error of measurement [SEM]). Results: All assessments had a significance level of p < 0.001 with an excellent Spearman’s r correlation coefficient between the participants’ total scores on the translated questionnaires ( rs = 0.911). The overall scores for the questionnaire and the individual items of the questionnaire revealed excellent internal consistency (α = 0.868) and reliability (SEM = 0.334). Conclusions: The validated and reliable translated questionnaire can be used by researchers and clinicians to assess physical activity levels in French paediatric populations.

Abstract
OBJECTIVE To assess the rates and timing of return to sport for the surgical management of proximal hamstring avulsions (PHAs). METHODS Three databases, PubMed, MEDLINE, and EMBASE, were searched from database inception until October 7, 2017, by 2 reviewers independently and in duplicate. The inclusion criteria were studies reporting return to sport outcomes for surgical management of acute, chronic, complete, and partial PHA. The rate of return to sports was combined in a meta-analysis of proportions using a random-effects model. RESULTS Overall, 21 studies with a total of 846 patients met the inclusion criteria, with a mean age of 41.4 years (range, 14-71 years) and a mean follow-up of 37.8 months (range, 6-76 months). Two studies were of prospective comparative design (level II), 2 were retrospective comparative (level III), 8 were prospective case series (level IV), and 9 were retrospective case series (level IV). The overall mean time to return to sport was 5.8 months (range, 1-36 months). The pooled rate of return to any sport participation was 87% [95% confidence interval (CI), 77%-95%]. The pooled rate of return to preinjury level of sport was 77% (95% CI, 66%-86%). CONCLUSIONS Pooled results suggest a high rate of return to sport after surgical management of PHA; however, this was associated with a lower preinjury level of sport. No major differences in return to sport were found between partial versus complete and acute versus chronic PHA.

Abstract
Injuries to the hamstring muscle complex are common in athletes, accounting for between 12% and 26% of all injuries sustained during sporting activities. Acute hamstring injuries often occur during sports that involve repetitive kicking or high-speed sprinting, such as American football, soccer, rugby, and athletics. They are also common in watersports, including waterskiing and surfing. Hamstring injuries can be career-threatening in elite athletes and are associated with an estimated risk of recurrence in between 14% and 63% of patients. The variability in prognosis and treatment of the different injury patterns highlights the importance of prompt diagnosis with magnetic resonance imaging (MRI) in order to classify injuries accurately and plan the appropriate management. Low-grade hamstring injuries may be treated with nonoperative measures including pain relief, eccentric lengthening exercises, and a graduated return to sport-specific activities. Nonoperative management is associated with highly variable times for convalescence and return to a pre-injury level of sporting function. Nonoperative management of high-grade hamstring injuries is associated with poor return to baseline function, residual muscle weakness and a high-risk of recurrence. Proximal hamstring avulsion injuries, high-grade musculotendinous tears, and chronic injuries with persistent weakness or functional compromise require surgical repair to enable return to a pre-injury level of sporting function and minimize the risk of recurrent injury. This article reviews the optimal diagnostic imaging methods and common classification systems used to guide the treatment of hamstring injuries. In addition, the indications and outcomes for both nonoperative and operative treatment are analyzed to provide an evidence-based management framework for these patients.

Abstract
Aims Despite the increase in the surgical repair of proximal hamstring tears, there exists a lack of consensus in the optimal timing for surgery. There is also disagreement on how partial tears managed surgically compare with complete tears repaired surgically. This study aims to compare the mid-term functional outcomes in, and operating time required for, complete and partial proximal hamstring avulsions, that are repaired both acutely and chronically. Methods This is a prospective series of 156 proximal hamstring surgical repairs, with a mean age of 48.9 years (21.5 to 78). Functional outcomes were assessed preinjury, preoperatively, and postoperatively (six months and minimum three years) using the Sydney Hamstring Origin Rupture Evaluation (SHORE) score. Operating time was recorded for every patient. Results Overall, significant improvements in SHORE scores were seen at both six months and mid-term follow-up. Preoperatively, acute patients (median score 27.1 (interquartile range (IQR) 22.9)) reported significantly poorer SHORE scores than chronic patients (median score 42.9 (IQR 22.1); p < 0.001). However, this difference was not maintained postoperatively. For partial tears, acutely repaired patients reported significantly lower preoperative SHORE scores compared to chronically reapired partial tears (median score 24.3 (IQR 15.7) vs median score 40.0 (IQR 25.0); p < 0.001) but also significantly higher SHORE scores at six-month follow-up compared to chronically repaired partial tears (median score 92.9 (IQR 10.7) vs. median score 82.9 (IQR 14.3); p < 0.001). For complete tears, there was only a difference in preoperative SHORE scores between acute and chronic groups. Overall, acute repairs had a significantly shorter operating time (mean 64.67 minutes (standard deviation (SD) 12.99)) compared to chronic repairs (mean 74.71 minutes (SD = 12.0); t = 5.12, p < 0.001). Conclusion Surgical repair of proximal hamstring avulsions successfully improves patient reported functional outcomes in the majority of patients, irrespective of the timing of their surgery or injury classification. However, reducing the time from injury to surgery is associated with greater improvement in patient outcomes and an increased likelihood of returning to preinjury functional status. Acute repair appears to be a technically less complex procedure, as indicated by reduced operating times, postoperative neurological symptoms and number of patients requiring bracing. Acute repair is therefore a preference among many surgeons. Cite this article: Bone Joint J 2020;102-B(10):1419–1427.

Orthop J Sports Med 2020; 8:2325967120946317. [PMID: 32923506 PMCID: PMC7457414 DOI: 10.1177/2325967120946317] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Accepted: 03/13/2020] [Indexed: 11/15/2022] Open
Abstract
Background No previous study has compared the outcomes of repair for partial and complete proximal hamstring ruptures at various intervals after the injury. Purpose The primary aim was to determine whether time from injury to surgery affected outcomes after primary repair of partial and complete proximal hamstring ruptures. The secondary aim was to assess patients' experiences from initial evaluation to finding a treating surgeon. Study Design Cohort study; Level of evidence, 3. Methods Records from 2007 to 2016 from a single surgeon's practice were reviewed. A total of 124 proximal hamstring repair procedures in 121 patients were identified. There were 92 patients who completed questionnaires: a custom survey, the standard Lower Extremity Functional Scale (LEFS), a custom LEFS, the standard Marx activity scale, a custom Marx activity scale, and the University of California Los Angeles (UCLA) activity score. Results were analyzed for partial and complete repair procedures performed at ≤3 weeks, ≤6 weeks, and >6 weeks after the injury. Results The mean follow-up was 43 months (median, 38 months). Of 93 repair procedures reviewed, 51% (9/28 partial; 38/65 complete), 79% (16/28 partial; 57/65 complete), and 22% (12/28 partial; 8/65 complete) were performed at ≤3 weeks, ≤6 weeks, and >6 weeks, respectively. At those various intervals, no statistical difference was found in standard LEFS, custom LEFS, standard Marx, custom Marx, or UCLA scores. Female sex, older age, and body mass index >30 kg/m2 were negative predictors of outcome measures. When repaired >6 weeks after the injury, a greater percentage of patients reported weakness of the operative leg compared with the contralateral side (partial tears: 6.3% vs 25%, respectively; complete tears: 24.6% vs 50%, respectively) in addition to greater sitting intolerance (partial tears: 0% vs 25%, respectively; complete tears: 7.1% vs 12.5%, respectively). Patients repaired >6 weeks after the injury visited, on average, 2.6 practitioners before an evaluation by the treating surgeon compared with 1.6 treated surgically at ≤6 weeks (P = .008). Conclusion Patients with proximal hamstring repair performed in the acute and chronic settings can expect successful outcomes but may experience more subjective weakness and difficulty with prolonged sitting when the repair is performed >6 weeks after the injury. Patients faced challenges in receiving the correct diagnosis and referral to an appropriate treating surgeon, emphasizing the need for an increased awareness of the injury.

Abstract
BACKGROUND Injuries to the hamstring complex most commonly involve the proximal musculotendinous junction of the long head of the biceps femoris (MTJ-BFlh). Nonoperative management of these injuries is associated with prolonged rehabilitation and high risk of recurrence. To our knowledge, the surgical management of acute MTJ-BFlh injuries has not been previously reported. HYPOTHESIS Surgical repair of acute MTJ-BFlh injuries enables return to sporting activity with low risk of recurrence. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 64 patients (42 male and 22 female) undergoing surgical repair of acute MTJ-BFlh injuries were included. Predefined outcomes were recorded at regular intervals after surgery. Mean follow-up time after surgery was 29.2 months (range, 24.0-37.1 months). RESULTS All study patients returned to their preinjury levels of sporting activity. Mean ± SD time from surgical intervention to return to sporting activity was 13.4 ± 5.1 weeks. Three patients had reinjury at the operative site: 1 (1.6%) with MTJ-BFlh injury and 2 (3.2%) with myofascial tears. At 3 months after surgery, patients had improved mean passive straight-leg raise (72.0° ± 11.4° vs 24.1° ± 6.8°; P < .001); increased mean isometric hamstring muscle strength at 0° (84.5 % ± 10.4% vs 25.9% ± 8.9%; P < .001), 15° (89.5% ± 7.3% vs 41.2% ± 9.7%; P < .001), and 45° (93.9% ± 5.1% vs 63.4% ± 7.6%; P < .001); higher mean Lower Extremity Functional Scale scores (71.5 ± 5.0 vs 29.8 ± 6.3; P < .001); and improved mean Marx activity rating scores (9.8 ± 2.2 vs 3.8 ± 1.9; P < .001), as compared with preoperative scores. High patient satisfaction and functional outcome scores were maintained at 1 and 2 years after surgery. CONCLUSION Surgical repair of acute MTJ-BFlh injuries enables return to preinjury level of sporting function with low risk of recurrence at short-term follow-up.

Abstract
PURPOSE The purpose of this study was to evaluate the outcomes of endoscopic proximal hamstring repair (ePHR), specifically: (1) functional and subjective outcomes, (2) effectiveness of treatment (preoperative-to-postoperative change), (3) complications, (4) acute versus chronic tears, and (5) partial versus complete tears. METHODS A retrospective case series of a single-surgeon database for all patients who underwent ePHR between November 2014 and January 2019 with a minimum 1-year follow-up (range, 12 to 48 months) was performed. Charts were analyzed for preoperative and postoperative passive range of motion (PROM), strength, VAS pain, UCLA activity, and modified Harris Hip Score (mHHS). Manual muscle strength testing based on standard grading scale of 0 to 5 was performed. Complications including re-tear of the repair site, infection, iatrogenic nerve injury, inability to return to work/sport at the same level as preinjury, persistent hamstring weakness, pain with sitting, and subsequent surgery were recorded. RESULTS We identified 20 ePHR (6 males, 14 females) with a mean age of 46 years (range, 18 to 63 years). At most recent follow-up, mean VAS pain was 1.85 (SD 2), UCLA activity was 8 (SD 2), mHHS was 90.6 (SD 10.5), and PROM hip flexion of 121.7° (SD 14.5°). Effectiveness of treatment demonstrated significant improvement in objective hamstring strength, hip flexion PROM by 17.3°, UCLA activity by 3, and VAS pain by 3 points. Subjective hamstring weakness was reported in 8 (42.1%) and persistent pain with sitting in 3 (15.8%). Return to work and sport were 100% and 95%, respectively. mHHS was significantly higher postoperatively in patients with complete versus partial tears (95.5 versus 85.7). CONCLUSION Endoscopic proximal hamstring repair is an effective approach that provides patients significant improvement in pain and function. LEVEL OF EVIDENCE IV, Case Series.

Excellent clinical outcome and low complication rate after proximal hamstring tendon repair at mid-term follow up. Knee Surg Sports Traumatol Arthrosc 2020; 28:1230-1235.

Abstract
PURPOSE Proximal hamstring tendon avulsions lead to a significant loss of strength and a functional deficit of the respective lower limb and surgery is the recommended treatment. Only little is known about the clinical outcomes and complications when comparing acute and chronic management as well as partial and complete tears. Therefore, the purpose of this study was to investigate the clinical results and the complication rate of patients after surgical treatment of proximal hamstring tendon injuries. It was hypothesized that surgical treatment of an acute proximal hamstring avulsion would lead to a superior clinical outcome with a low complication rate and high return to sports rate compared to chronic cases and partial avulsions. METHODS Patients who underwent proximal hamstring tendon repair between 2008 and 2015 were retrospectively evaluated with a minimum follow up of 2 years. Outcome measurements were obtained by means of Lysholm score, Harris Hip Score, Visual Analog Scale, and Tegner Activity Scale. Return to sports (RTS) rate was determined. Postoperative adverse events were recorded and complications reported. Patients' outcomes were compared between acute/chronic repair and partial/complete injury patterns. RESULTS Ninety-four of 120 (78.3%) were available for final assessment at a mean follow-up of 56.2 ± 27.2 months. Clinical outcome measures were excellent and did not differ between the treatment groups or between the different injury patterns. RTS was achieved by 86.2% of the patients and was significantly superior after acute treatment (p < 0.05). The overall complication rate was 8.5% and significantly higher in complete tears compared to partial tears and in delay compared to acute surgery (p < 0.05). CONCLUSION Surgical treatment of proximal hamstring tendon avulsions results in excellent clinical outcome scores and a high RTS rate. Open surgical treatment has shown to be a safe procedure with a low complication rate. Surgical timing is important, as early surgical intervention provides a higher RTS rate and a lower complication rate than delayed surgery and should therefore be preferred in clinical practice. Repair of partial and complete tears lead to similar clinical outcome, but a higher complication rate in complete avulsions. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Chronic incomplete proximal hamstring avulsion injuries are debilitating injuries associated with prolonged periods of convalescence and poor return to preinjury level of function. This study explores the efficacy of operative intervention for these injuries on patient satisfaction, muscle strength, range of motion, functional performance, return to preinjury level of sporting activity, and injury recurrence. HYPOTHESIS Surgical intervention of chronic incomplete proximal hamstring avulsion injuries enables return to preinjury level of sporting function with low risk of clinical recurrence. STUDY DESIGN Case series: Level of evidence, 4. METHODS This prospective single-surgeon study included 41 patients with incomplete proximal hamstring avulsion injuries refractory to 6 months of nonoperative treatment. All study patients underwent primary operative repair of the avulsed proximal hamstring tendon and received standardized postoperative rehabilitation. Predefined outcomes were recorded at regular intervals after surgery. Mean follow-up time was 28.2 months (range, 25.0-35.0 months) from date of surgery. RESULTS All patients returned to their preinjury level of sporting activity. Mean ± SD time from surgery to return to full sporting activity was 22.2 ± 6.7 weeks. There were no episodes of clinical recurrence. At 3 months after surgery, 39 patients (95.1%) were satisfied/very satisfied with the outcomes of their surgery, and as compared with preoperative values, improvements were recorded in isometric hamstring muscle strength at 0° (84.9% ± 10.9% vs 40.4% ± 8.8%; P < .001), 15° (89.6% ± 7.6% vs 44.2% ± 11.1%; P < .001), and 45° (94.1% ± 5.1% vs 66.4% ± 9.0%; P < .001); mean passive straight leg raise angle (71.2°± 13.5° vs 45.4°± 11.9°; P < .001); mean lower extremity functional score (70.9 ± 5.1 vs 48.4 ± 5.2; P < .001); and mean Marx activity rating score (5.6 ± 2.8 vs 2.7 ± 1.0; P < .001). High patient satisfaction and functional outcome scores were maintained at 1- and 2-year follow-up. CONCLUSION Operative repair of chronic incomplete proximal hamstring avulsion injuries enabled return to preoperative level of sporting function with no episodes of clinical recurrence at short-term follow-up. Surgical intervention was associated with high patient satisfaction and improved isometric hamstring muscle strength, range of motion, and functional outcome scores as compared with preoperative values. High patient satisfaction and improved functional outcomes were sustained at 2-year follow-up.

Proximal hamstring tendon avulsion injuries occur predominately in middle-aged patients with distinct gender differences: epidemiologic analysis of 263 surgically treated cases. Knee Surg Sports Traumatol Arthrosc 2020; 28:1221-1229. [PMID: 31541291 DOI: 10.1007/s00167-019-05717-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 09/11/2019] [Indexed: 11/28/2022]
Abstract
PURPOSE Epidemiologic data of proximal hamstring avulsions have mainly been reported in relatively small patient cohorts. Detailed information on patient demographics, injury mechanism, and injury patterns is lacking in the literature. Since these injuries are rare and frequently misdiagnosed, a better understanding may help to increase awareness and to improve diagnosis of proximal hamstring avulsions. METHODS A chart review was performed to identify all patients who had undergone surgical repair for complete proximal hamstring avulsions between 01/2006 and 02/2019 at the authors' institution. The following demographic and injury-specific data were obtained: Sex, age, body mass index (BMI), cause of injury (sports, activities of daily living, and others), presence of neurologic symptoms referable to the sciatic nerve, time to surgery, injury pattern (affected tendons), tendon retraction, and type of injury according to Wood et al.`s classification (Type 1: osseous avulsions, Type 2: tear at the musculotendinous junction, Type 3: incomplete avulsion from bone, Type 4: complete avulsion with only minimal retraction, and Type 5: complete avulsion with retraction > 2 cm). Data were analyzed for the entire study population and group comparison was performed with regard to sex, cause of injury, and the type of injury. RESULTS A total of 263 patients were included (53% male). The mean age was 49 ± 13 years with most patients (56%) aged between 45-59 years. Most injuries occurred while participating in sports (52%) and injury type 5 was most commonly diagnosed (66%). Five percent of patients had sensory deficits referable to the sciatic nerve. Gender comparison showed that female patients were significantly older, predominantly represented in the age group 45-59 years, and most commonly injured during activities of daily living, whereas male patients were significantly more often represented in younger age groups, and the most common cause of injury was sports. Compared to Type 4 and 5 injuries, patients with a Type 1 injury were significantly younger and had a significantly longer time to surgery. CONCLUSION Proximal hamstring avulsion occurs predominately in the middle-aged patient and only rarely in patients under the age of 30 years. No gender dominance exists. Female patients are typically older and get injured during activities of daily living, whereas male patients are younger and get injured more often during sports. These epidemiologic data may help physicians to make an accurate and early diagnosis. LEVEL OF EVIDENCE IV.

Abstract
AIMS To validate the Sydney Hamstring Origin Rupture Evaluation (SHORE), a hamstring-specific clinical assessment tool to evaluate patient outcomes following surgical treatment. METHODS A prospective study of 70 unilateral hamstring surgical repairs, with a mean age of 47.3 years (15 to 73). Patients completed the SHORE preoperatively and at six months post-surgery, and then completed both the SHORE and Perth Hamstring Assessment Tool (PHAT) at three years post-surgery. The SHORE questionnaire was validated through the evaluation of its psychometric properties, including; internal consistency, reproducibility, reliability, sensitivity to change, and ceiling effect. Construct validity was assessed using Pearson's correlation analysis to examine the strength of association between the SHORE and the PHAT. RESULTS The SHORE demonstrated an excellent completion rate (100%), high internal consistency (Cronbach's alpha 0.78), and good reproducibility (intraclass correlation coefficient (ICC) 0.82). The SHORE had a high correlation with the validated PHAT score. It was more sensitive in detecting clinical change compared to the PHAT. A ceiling effect was not present in the SHORE at six months; however, a ceiling effect was identified in both scores at three years post-surgery. CONCLUSION This study has validated the SHORE patient reported outcome measure (PROM) as a short, practical, reliable, valid, and responsive tool that can be used to assess symptom and function following hamstring injury and surgical repair.

Abstract
Proximal hamstring avulsion injuries can represent a challenging problem and lead to severe patient morbidity if not treated appropriately. The most common method for acute surgical fixation involves the use of between two and five suture anchors in a variety of configurations. The five-anchor fixation has become the gold standard due to the increased biomechanical stability. However, the technique has also been criticized due to the need for greater exposure and technical difficulty. We report on an individual with a proximal hamstring avulsion injury who was managed with a modified approach, utilizing only three anchors in a suture bridge technique. The patient had good clinical outcomes at their 3-month follow-up visit, demonstrating this technique to be a viable option that is less technically demanding.

Abstract
Objective: Proximal ischial hamstring avulsion injuries are relatively uncommon. As such, the management of these injuries is often highly variable. Consensus agreement is lacking for the indications for repair, along with the operative technique, and post-operative rehabilitation. The purpose of this study was to survey surgeons who treat proximal hamstring avulsion injuries to identify current trends in the management of this injury.Methods: After IRB approval, a 46-question cross-sectional survey was distributed using a secure electronic survey portal. The survey sought to determine surgeon experience, diagnostic preferences, treatment patterns, surgical indications/technique, perceived patient outcomes, surgical complications, as well as post-operative management and rehab protocols. Surveys were completed electronically and anonymously, with invitations distributed to members of the American Orthopedic Society for Sports Medicine (AOSSM) and Arthroscopy Association of Canada (AAC).Results: A total of 108 surgeons who manage proximal hamstring injuries completed the survey. Most respondents (77%) treat one to five of these injuries per year. MRI was the preferred imaging modality to confirm diagnosis. Despite 98% of respondents indicating that there was a role for surgical management of proximal hamstring avulsions, operative treatment was reportedly undertaken in only 50% of cases seen by each respondent. The top three reported surgical indications were: number of tendons involved (most important factor = 42%, second most = 26%, third most = 13%), amount of tendon retraction (28%, 41%, 16%), and patient activity level (16%, 18%, 24%).Conclusion: Based on the practice patterns of the surgeons who completed the survey, there is continued disparity in the management of proximal hamstring avulsions. A lack of agreement exists with regards to surgical indications, operative technique, and post-operative protocols. Most striking is the rate of non-operative treatment and perceived rate of poor outcomes within this cohort. Future research should focus on objective evaluation of non-operative management, and additional variables involved in surgical treatment and post-operative rehabilitation.

Biomechanical Evaluation of Proximal Hamstring Repair: All-Suture Anchor Versus Titanium Suture Anchor. Orthop J Sports Med 2020; 8:2325967119892925. [PMID: 31921936 PMCID: PMC6940602 DOI: 10.1177/2325967119892925] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Accepted: 10/25/2019] [Indexed: 11/20/2022] Open
Abstract
Background: Proximal hamstring avulsions are severe tendon injuries and are commonly
sports-related. Open and endoscopic techniques as well as different anchor
configurations have already been described for proximal hamstring repair.
Novel all-suture anchors have been developed to provide decreased bone loss
during placement and reduced occupied bone volume when compared with
titanium suture anchors. Hypothesis: Complete proximal hamstring avulsions repaired with all-suture anchors will
demonstrate equal load to failure and comparable displacement under cyclic
loading when compared with titanium suture anchors. Study Design: Controlled laboratory study. Methods: Complete proximal hamstring avulsions were created in 18 paired cadaveric
specimens (mean ± SD age, 63.0 ± 10.4 years). Either all-suture anchors or
titanium suture anchors were used for repair. Cyclic loading from 10 to 125
N at 1 Hz was performed for 1500 cycles with a material testing machine.
Displacement was assessed along anterior and posterior aspects of the tendon
repair with optical tracking. Specimens were loaded to failure at a rate of
120 mm/min. Displacement, load to failure, and repair construct stiffness
were compared between matched pairs with the Wilcoxon signed-rank test.
Correlations were determined by Spearman rho analysis. Results: The all-suture anchors showed significantly higher load-to-failure values
when compared with the titanium anchor repairs (799.64 ± 257.1 vs 573.27 ±
89.9 N; P = .008). There was no significant difference in
displacement between all-suture anchors and titanium suture anchors at the
anterior aspect (6.60 ± 2.2 vs 5.49 ± 1.1 mm; P = .26) or
posterior aspect (5.87 ± 2.08 vs 5.23 ± 1.37 mm; P = .678)
of the repaired hamstring tendons. Conclusion: All-suture anchors demonstrated similar displacement and superior load to
failure when compared with titanium suture anchors. Clinical Relevance: The results of this study suggest that all-suture anchors are an equivalent
alternative to titanium suture anchors for proximal hamstring avulsion
repair.

Abstract
BACKGROUND Partial avulsions of the proximal hamstring origin remain a challenging problem with nonoperative treatments frequently providing limited success. The literature is limited regarding the outcomes of operative management in the active and athletic population. HYPOTHESIS Surgical fixation of proximal hamstring ruptures will have favorable outcomes at midterm follow-up. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 64 patients with partial avulsions of the proximal hamstring origin treated with surgical fixation by a single surgeon were reviewed at a 2-year minimum follow-up. All patients had initially undergone failed nonoperative treatment. Patient-reported outcome scores on the Lower Extremity Functional Score (LEFS), Marx Activity Rating Scale, custom LEFS and Marx scales, and total proximal hamstring score were evaluated. Data on patient-perceived strength, return to sport, and satisfaction were also collected. RESULTS The cohort included 27 male and 37 female (N = 64) patients with a mean age of 47.3 years (range, 16-65 years), and all were reviewed at a mean 6.5-year (range, 2-12.5 years) follow-up. The average postoperative LEFS was 96% (range, 68%-100%), with the custom LEFS being 90% (range, 39%-100%). The mean Marx score was 12.4 (range, 4-16). The Marx custom score demonstrated no disability with activities of daily living. The mean total proximal hamstring score was 94% (range, 69%-100%). No differences in any outcome measures were seen when comparing acute versus chronic repairs. Three patients underwent further hamstring surgery. No patients reported symptoms of numbness in the operative extremity at rest, while 3 patients had a superficial stitch abscess treated with antibiotics alone. The most commonly reported difficulty was with prolonged sitting. Ninety-seven percent were satisfied with surgery, 92% reported they could participate in strenuous activity, and 97% estimated their strength to be >75%, while 64% estimated it to be 100% of their contralateral side. Patients returned to sport at an average of 11.1 months, and all that returned were satisfied with their performance. CONCLUSION Both early and delayed anatomic surgical repair of partial proximal hamstring avulsions leads to successful functional outcomes, a high rate of return to athletic activity, and low complication rates at the 6.5-year follow-up. Nonoperative treatments should first be attempted.

Abstract
Hamstring injuries are common in athletes and can cause notable disability. They can be separated based on proximal, muscle belly, and distal injuries, with proximal and distal injuries more commonly requiring surgical intervention. Most injuries do not require acute MRI; however, MRI is useful in proximal and distal injuries as well as muscle belly tears that fail to respond to nonsurgical treatment. Acute repair of proximal avulsions, both partial and complete, result in successful outcomes, whereas chronic complete repairs are more difficult and less reliable. Muscle belly injuries have predictable outcomes but recurrence is common. Nonsurgical treatments focus on eccentric strengthening with the possible addition of low WBC platelet-rich plasma, which may have the potential to hasten recovery and decrease re-rupture. Distal injuries are relatively rare but may require surgical intervention. Hamstring reinjury is common, making continuation of preventive therapies after return to sport essential. Future research with larger sample sizes are required to determine how to decrease injury and reinjury rates, to evaluate the efficacy of platelet-rich plasma and to determine other treatments that may accelerate recovery after injury.

Abstract
Proximal hamstring tendon avulsions are typically sustained during forced hip hyperflexion combined with knee extension. We present 3 cases of athletes with a proximal hamstring tendon avulsion caused by an alternative injury mechanism that also involves a considerable hip abduction component (flexion-abduction injury mechanism). All cases had at least one concurrent injury of the medial thigh muscles, either on the ipsilateral or contralateral side. The 2 elite athletes with this injury mechanism returned to sport at preinjury level relatively quickly. A history of the flexion-abduction mechanism should raise suspicion of a hamstring tendon avulsion with concomitant injury of the medial thigh muscles. The magnetic resonance imaging (MRI) protocol should include both legs, and any concurrent injury may need to be addressed as well. In future studies, it would be interesting to investigate whether injury mechanism holds prognostic value in proximal hamstring tendon avulsions.

Abstract
PURPOSE To assess outcomes of patients who underwent proximal hamstring repair utilizing an accelerated rehabilitation protocol with immediate weight bearing as tolerated and no bracing. METHODS Retrospective chart review identified 47 proximal hamstring tendon repairs with suture anchors in 43 patients performed during 2008-2015. Rehabilitation included no immobilization or limited weightbearing. Patients were contacted by phone to assess outcomes utilizing the lower extremity functional score (LEFS), single-assessment numeric evaluation (SANE), and Marx activity scale. Overall patient-reported scores were calculated and results of acute and chronic repairs compared. RESULTS Thirty-four patients (38 repairs, 80.8%) were available for follow-up at mean of 4.1 ± 2.0 years following repair. There were two re-tears: one complete rupture 5 weeks postoperative and one partial rupture 10 weeks postoperative in the chronic group. Patients in general reported low pain and good function with a mean LEFS score of 87 ± 21%, a mean SANE score of 88.1 ± 11.6, and a mean numeric pain score of 8.5 ± 15.3 in the last week and 12.2 ± 21.1 with activity. The acute repair group was noted to have a higher mean LEFS score (93.7 versus 79.8%, p = 0.004) and SANE score (91.3 versus 83.8, p = 0.047), and lower pain with activity (21.7 versus 4.8, p < 0.001) as compared to the chronic group. CONCLUSIONS Repair of acute proximal hamstring ruptures results in good function and pain relief with the use of a rehabilitation protocol that does not require weight-bearing restrictions or bracing. LEVEL OF EVIDENCE III, therapeutic.

Abstract
BACKGROUND Proximal hamstring tendon avulsions are debilitating and commonly cause pain, weakness, and functional limitations. Open surgical repair has been the standard, but improved endoscopic techniques have enabled proximal hamstring fixation with decreased risk of infection and numbness, without the morbidity of a large incision. PURPOSE/HYPOTHESIS The purpose was to (1) describe pertinent anatomy surrounding the proximal hamstring origin in relation to 4 endoscopic portal sites and (2) test for biomechanical differences between open and endoscopic repair. It was hypothesized that (1) endoscopic proximal hamstring repair is efficacious with respect to commonly used portals and (2) there is no biomechanical difference between open and endoscopic techniques. STUDY DESIGN Descriptive and controlled laboratory study. METHODS Proximal hamstring ruptures were simulated endoscopically in 10 fresh-frozen human cadaveric pelvis specimens. Endoscopic repair was then completed on 1 limb from each specimen through 4 portals. After repair, each specimen was dissected in layers and measurements from portal tracts to pertinent anatomy were obtained. Open repair was performed on all contralateral limbs, followed by cyclical biomechanical tensile testing to failure of both the open and endoscopically repaired hamstring tendons to assess failure load and local tissue strain. RESULTS On average, no portal tract was closer than 2.0 cm to the sciatic nerve or inferior gluteal neurovascular bundle. Anatomic landmarks were identified that could improve the reproducibility and safety of the procedure. Biomechanical testing revealed no differences between the open and endoscopic repair techniques for any measured parameter. CONCLUSION This study supports the safety and efficacy of endoscopic proximal hamstring repair through anatomic and biomechanical analyses and helps establish reproducible and recognizable landmarks that define a safe working zone. CLINICAL RELEVANCE This study maps the anatomic landscape of the proximal hamstring as encountered endoscopically and demonstrates equivalent biomechanical strength of endoscopic proximal hamstring repair, supporting this technique's safety and efficacy.

Abstract
PURPOSE To report outcomes following proximal hamstring reconstruction employing an ipsilateral distal hamstring tendon autograft, in patients with chronic proximal ruptures. METHODS Six patients presenting with a chronic proximal hamstring avulsion and a medial time from injury of 11.0 months (range 7-18), confirmed via magnetic resonance imaging, underwent proximal hamstring repair using a free graft harvested from the ipsilateral distal hamstrings. Patients were evaluated at 6, 12 and 24 months post-surgery, via the Perth Hamstring Assessment Tool, the Short Form Health Survey, the Lower Extremity Functional Scale, a Patient Satisfaction Questionnaire, the Active Knee Extension and 6 min walk tests, the single and triple hop tests for distance, and isokinetic knee extensor and flexor strength. Knee strength was assessed at 180° and 240°/s (total work, peak and average torque), and both mean absolute scores and limb symmetry indices (LSIs) comparing the operated and non-operated limbs were presented. RESULTS Patients demonstrated good clinical improvement throughout the post-operative timeline in all subjective and objective outcomes. Mean knee extensor LSIs had recovered by 12 and 24 months. At 24 months post-surgery, while mean LSIs for knee flexor peak and average torque were at (or above) 90%, a significant difference still existed between the operated and non-operated limbs in knee flexor total work. At 24 months, five patients (83%) were satisfied with the results of the surgery, as well as their ability to return to recreational and sporting activities. There were two adverse events including an early deep vein thrombosis and a secondary surgery to remove a loosened staple. CONCLUSIONS While isokinetic hamstring strength had not fully recovered by 24 months, this surgical technique demonstrated a high level of patient satisfaction and return to function, in patients with chronic proximal hamstring ruptures. As the clinical relevance, this surgical technique provides a viable option with good post-operative outcomes for patients with chronic proximal hamstring tears that cannot be approximated back to the ischium.
