Abstract
PURPOSE To evaluate the mid-term clinical outcomes for the non-surgical and surgical management of acute proximal hamstring avulsions. METHODS Sixty physically active individuals were offered surgical or non-surgical management for their proximal hamstring avulsion injuries. Distal retraction was defined as greater than 2 cm. Primary outcome measures were the Victorian Institute of sport assessment-proximal hamstring tendons (VISA-H) and functional assessment scale for acute hamstring injuries (FASH). Secondary outcome measures included palpable gap (cm), return to sport (RTS) and the ability to perform Nordic hamstring curls. Outcome variables were adjusted in regression models for gender, age, and treatment. RESULTS Thirty-one patients elected to undertake non-surgical management, and 29 chose surgery with a mean follow-up of 34.8 ± 8.7 and 34.9 ± 7.0 months, respectively. The mean VISA-H for the non-surgical and surgical groups were 87.3 ± 3.4 and 87.9 ± 4.1 (n.s.), respectively. The mean FASH for the non-surgical group was 89.3 ± 2.4 and 88 ± 3.6 for the surgical group (n.s.). This was consistent after adjusting for confounders. The mean gap for the non-surgical group was 4.5 ± 1.09 and 4.9 ± 1.19 cm for the surgical group (n.s.). No significant differences were found in the abilities to perform Nordic hamstring curls (n.s.). Both groups achieved comparable RTS rates (n.s.). On average, the non-surgical group achieved RTS at 5.5 ± 1.2 months post-injury, whereas the surgical group was at 5.7 ± 0.7 months (n.s.). CONCLUSION Physically active individuals with acute proximal hamstring avulsions and distal retraction of the tendon stump can be managed non-surgically, achieving similar functional levels and RTS compared to patients treated surgically. LEVEL OF EVIDENCE Level III.

Abstract
Proximal hamstring injuries are a common sports and recreational injury among the active patient population. Surgical fixation of the tendons of the hamstring muscle complex, as opposed to conservative treatment alone, has shown improved patient outcomes, prompting the evolution of the suture anchors utilized in these repairs. Previous studies investigating the biomechanical properties of hamstring repair anchors have focused on double-row knotless techniques, in which the fixation of the overall construct relies on each individual anchor to maintain fixation. While these constructs have demonstrated biomechanical strength and clinical durability, each suture anchor represents a potential point of failure for the entire construct due to the crossed stitch anchor configuration. To address this limitation, recent tensionable knotless all-suture anchor designs have been implemented with success due to their smaller size and biomechanical strength. The aim of this technical note is, thus, to describe a technique for proximal hamstring repair using a tensionable knotless all-suture anchor construct that has 5 independent mattress sutures and, in doing so, employs the biomechanical strength of knotless fixation but eliminates the potential single point of failure seen with current knotless suture anchor designs.

Abstract
BACKGROUND Proximal hamstring tendon avulsions (PHAs) may be treated nonoperatively or operatively. Little is known about the result of the injury, and its treatment, on the quality and function of the hamstring muscle after healing and rehabilitation. We hypothesized that the injured leg would have greater fatty infiltration and atrophy than the uninjured leg at follow-up and that these findings would correlate to muscle weakness. METHODS In a cross-sectional cohort study, 48 patients treated for PHA, either operatively or nonoperatively, were re-examined 2-11 years post-treatment. We measured muscle strength with isokinetic strength tests, and muscle volume and fatty infiltration with MRI. Primary outcomes were hamstring muscle quality, quantified by outlining the cross-sectional area slice-by-slice, and the degree of fatty infiltration estimated using the Goutallier grading method. Secondary outcome was concentric isokinetic hamstring muscle strength measured using BioDex at 60°/sec and tendon attachment assessed on MRI. Comparisons with the outcomes of the uninjured leg were made. RESULTS The total hamstring muscle volume was on average reduced by 9% (SD ± 11%, p < 0.001) compared to that of the uninjured leg. Fatty infiltration was significantly more severe in the injured hamstrings than in the uninjured hamstrings (p < 0.001). This was also true when only analyzing operatively treated patients. The reduction in muscle volume and increase in fatty infiltration correlated significantly (r = 0.357, p = 0.013), and there was also a statistically significant correlation with muscle atrophy and reduction in isokinetic strength (r = 494, p < 0.001). CONCLUSION PHA injuries result in fatty infiltration and muscle atrophy and the muscle quality impairment correlates with residual muscle weakness.

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 Ischial tuberosity apophyseal fractures are avulsion fractures of the anatomic footprint of the proximal hamstring tendons. Generally, these injuries are rare and frequently occur in skeletally immature, active patients due to incomplete ossification. Depending on the fragment displacement, non-operative or operative treatment approaches are used. Case presentation We report a case of a 29-year-old professional volleyball athlete who has suffered from a nonunion avulsion fracture for 14 years. Isolated suture anchor fixation was performed after open excision of a large bony fragment followed by excellent clinical and functional outcome at 1 year postoperatively. Conclusion In conclusion, avulsion fractures of the ischial tuberosity with large fragments and restrictions to activities of daily living due to pain can, in individualized cases, be treated with an open excision of the fragment followed by repair of the proximal hamstring tendons using suture anchors.

Abstract
Objectives: Hamstring injuries are common and can now be accurately diagnosed. In addition, novel surgical indications have been introduced. However, evidence-based guidelines on the hamstring injuries in management of top-level athletes are missing. Methods: The management methods and outcomes of treatment are classically based on relatively small case series. We discuss a novel concept based on the fact that each tendon of the hamstrings muscle should be managed in an individual fashion. Furthermore, suitable indications for hamstring surgery in athletes are introduced. Results: The present study introduces modern treatment principles for hamstring injury management. Typical clinical and imagining findings as well as surgical treatment are presented based on a critical review of the available literature and personal experience. Conclusions: Hamstring injuries should not be considered to be all equal given the complexity of this anatomical region: The three separate tendons are different, and this impacts greatly on the decision-making process and outcomes in athletes.

Abstract
OBJECTIVE The goal of this study was to characterize the risk of intraoperative injury to the posterior femoral cutaneous nerve and to evaluate potential risk factors for injury during surgical repair of proximal hamstring injuries. DESIGN Retrospective cohort study. SETTING Single tertiary referral center. PATIENTS The cohort consisted of all patients presenting to a single institution with a proximal hamstring avulsion injury who were managed with surgical repair between January 1, 2000 and August 1, 2016. A total of 67 patients were included in the cohort. INDEPENDENT VARIABLES Variables assessed for their association with postoperative numbness in the distribution of the posterior femoral cutaneous nerve included age, sex, body mass index, mechanism of injury, time to surgical repair, and incision used. MAIN OUTCOME MEASURES The primary outcome of interest was neurologic symptoms referable to the posterior femoral cutaneous nerve. RESULTS Postoperatively, 13 patients (19%) developed new numbness in the distribution of the posterior femoral cutaneous nerve. One patient reported neuropathic pain and paresthesias associated with the numbness. The use of a gluteal crease incision was the only predictive factor for postoperative numbness in the posterior femoral cutaneous nerve distribution (odds ratio 8.67; 95% confidence interval, 2.30-42.80; P = 0.001). CONCLUSIONS The current study provides data that can be used in discussing the risks and benefits of surgical repair with patients and when weighing the pros and cons of using a gluteal crease versus longitudinal incision.

Abstract
PURPOSE The aim of this study was to perform a long-term follow-up of patients treated for an Achilles tendon re-rupture, using established outcome measurements for tendon structure, lower extremity function and symptoms, and to compare the results with those for the uninjured side. A secondary aim was to compare the outcome with that of patients treated for primary ruptures. The hypotheses were that patients with a re-rupture recover well, and have similar long-term outcome as primary ruptures. METHODS Twenty patients (4 females) with a mean (SD) age of 44 (10.9) years, ranging from 24 to 64, were included. The patients were identified by reviewing the medical records of all Achilles tendon ruptures at Sahlgrenska University Hospital and Kungsbacka Hospital, Sweden, between 2006 and 2016. All patients received standardised surgical treatment and rehabilitation. The mean (SD) follow-up was 51 (38.1) months. A test battery of validated clinical and functional tests, patient-reported outcome measurements and measurements of tendon elongation were performed at the final follow-up. This cohort was then compared with the 2-year follow-up results from a previous randomised controlled trial of patients treated for primary Achilles tendon rupture. RESULTS There were deficits on the injured side compared with the healthy side in terms of heel-rise height (11.9 versus 12.5 cm, p = 0.008), repetitions (28.5 versus 31.7, p = 0.004) and drop-jump height (13.2 versus 15.1 cm, p = 0.04). There was a significant difference in calf circumference (37.1 versus 38.4 cm, p =< 0.001) and ankle dorsiflexion on the injured side compared with the healthy side (35.3° versus 40.8°, p = 0.003). However, no significant differences were found in terms of tendon length 22.5 (2.5) cm on the injured side and 21.8 (2.8) cm on the healthy side. Compared with primary ruptures, the re-rupture cohort obtained significantly worse results for the Achilles tendon total rupture score, with a mean of 78 (21.2) versus 89.5 (14.6) points, (p = 0.007). The re-ruptures showed a higher mean LSI heel-rise height, 94.7% (9.3%) versus 83.5% (11.7%) (p = < 0.0001), and superior mean LSI eccentric-concentic power, 110.4% (49.8%) versus 79.3% (21%) (p = 0.001), than the primary ruptures. CONCLUSION The results of this study indicate that patients with an Achilles tendon re-rupture had continued symptoms and functional deficits on the injured side, after a long-term follow-up. Patients with an Achilles tendon re-rupture had worse patient-reported outcomes but similar or superior functional results compared with patients with primary ruptures.

Abstract
BACKGROUND Proximal Hamstring Tendinopathy-related Sciatic Nerve Entrapment (PHTrSNE) is a neuropathy caused by fibrosis interposed between the semimembranosus tendon and the sciatic nerve, at the level of the ischial tuberosity. METHODS Ultrasound-guided Intratissue Percutaneous Electrolysis (US-guided EPI) involves galvanic current transfer within the treatment target tissue (fibrosis) via a needle 0.30 to 0.33 mm in diameter. The galvanic current in a saline solution instantly develops the chemical process of electrolysis, which in turn induces electrochemical ablation of fibrosis. In this article, the interventional procedure is presented in detail, and both the strengths and limits of the technique are discussed. RESULTS US-guided EPI eliminates the fibrotic accumulation that causes PHTrSNE, without the semimembranosus tendon or the sciatic nerve being directly involved during the procedure. The technique is however of limited use in cases of compression neuropathy. CONCLUSION US-guided EPI is a technique that is quick to perform, minimally invasive and does not force the patient to suspend their activities (work or sports) to make the treatment effective. This, coupled to the fact that the technique is generally well-tolerated by patients, supports use of US-guided EPI in the treatment of PHTrSNE.

Abstract
Muscle injuries are the most common injuries in sports, with hamstring injuries accounting for 29% of all injuries in athletes. These injuries lead to prolonged impairment and have a reinjury risk of 12% to 31%. They range from mild muscle damage without loss of structural integrity to complete muscle tearing with fiber disruption. Novel MRI scores are increasingly being used and allow a more precise prediction of return to sport. In this article, the authors review the history, mechanisms of injury, and classification systems for hamstring injuries as well as present the latest evidence related to the management of hamstring injuries, including intramuscular and both proximal and distal insertional injuries. Indications for surgical treatment of certain proximal and distal avulsions, biological augmentation to the nonoperative treatment of midsubstance injuries, and advances in risk reduction and injury prevention are discussed.

Abstract
Incomplete avulsion of the proximal hamstrings can be a severely debilitating injury that causes weakness, pain while sitting and inability to run. The results of the surgical treatment of 23 consecutive patients with such injuries at least two years after surgery are described. The surgery consisted of the repair of the hamstrings directly onto the ischial tuberosity. At review, using a visual analogue scale (VAS, 0 to 100), pain while sitting improved from a mean of 40 (0 to 100) to 64 (0 to 100) (p = 0.024), weakness from a mean of 39 (0 to 90) to 76 (7 to 100) (p = 0.0001) and the ability to run from a mean of 24 (0 to 88) to 64 (0 to 95) (p = 0.0001). According to a VAS, satisfaction was rated at a mean of 81 (0 to 100) and 20 patients (87%) would have the same procedure again. Hamstring strength measured pre- and post-operatively had improved significantly from a mean of 64% (0% to 95%) to 88% (50% to 114%) compared with the normal side. Most of these patients with symptomatic incomplete hamstring avulsions unresponsive to conservative treatment had an improved outcome after surgical repair.

Abstract
Low back pain and leg pain commonly occur together. Multiple factors can cause low back related leg pain; therefore, identification of the source of symptoms is required in order to develop an appropriate intervention program. The patient in this case presented with low back and leg pain. A patho-mechanism based classification is described in combination with the patient's subjective and objective examination findings to guide treatment. The patient's symptoms improved marginally with intervention addressing primarily the musculoskeletal impairments and with intervention addressing primarily the neurodynamic impairments. Full functional improvements were attained with a manual therapy intervention directed at both mechanisms simultaneously. The approach described in this case address a mixed pathology utilizing passive accessory and passive physiological lumbar mobilizations in combination with lower extremity neurodynamic mobilization. The patient reported complete resolution of symptoms after a total of seven visits over a period of 6 weeks. While specific guidelines do not yet exist for treatment based on the classification approach utilized, this case report provides an example of manual therapy to address low back related leg pain of mixed pathology.

Abstract
BACKGROUND Hamstring muscle strains often recur. The authors studied the effect of the grade of initial injury on the subsequent risk of reinjury. HYPOTHESIS No difference in reinjury rate between acute low-grade (grades I and II) and high-grade (III and IV) hamstring muscle strains would be seen. STUDY DESIGN Cohort study (prognosis); Level of evidence, 1. METHODS Between 1999 and 2007, the authors managed 165 elite track and field athletes with acute, first-time unilateral hamstring muscle strains. Strains were classified into 4 grades (I, II, III, and IV) based on knee active range of motion deficit at 48 hours. The same rehabilitation protocol was prescribed, and the rate of reinjury was recorded during the following 24 months. RESULTS The average time to return to sport after initial injury was 7.4 days for grade I injuries, 12.9 days for grade II injuries, 29.5 days for grade III injuries, and 55.0 days for grade IV injuries. At follow-up, 23 of the 165 athletes (13.9%) had experienced a second hamstring muscle strain. Of the 75 athletes with a grade I injury, 7 (9.3%) had experienced a recurrence after 24 months. Of the 58 athletes with a grade II injury, 14 (24.1%) experienced a recurrence. Of the 26 athletes with a grade III injury, 2 (7.7%) experienced a recurrence, and of the 6 athletes with a grade IV injury, none had experienced a recurrence after 24 months. CONCLUSION Low-grade hamstring muscle lesions appear to lead to a higher risk of reinjury than high-grade hamstring muscle lesions. However, there were disproportionately fewer high-grade injuries than low-grade injuries. Objective clinical findings can accurately determine the risk of reinjury after acute hamstring muscle strains in elite track and field athletes.
