Comparison of Pain Scores and Functional Outcomes of Patients Undergoing Arthroscopic Hip Labral Repair and Concomitant Capsular Repair or Plication Versus No Closure. Orthop J Sports Med 2024; 12:23259671241243303. [PMID: 38646603 PMCID: PMC11032060 DOI: 10.1177/23259671241243303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Accepted: 10/11/2023] [Indexed: 04/23/2024] Open
Abstract
Background The need for capsular closure during arthroscopic hip labral repair is debated. Purpose To compare pain and functional outcomes in patients undergoing arthroscopic hip labral repair with concomitant repair or plication of the capsule versus no closure. Study Design Cohort study. Methods Outcomes were compared between patients undergoing arthroscopic hip labral repair with concomitant repair or plication of the capsule versus no closure at up to 2 years postoperatively and with stratification by age and sex. Patients with lateral center-edge angle <20°, a history of instability, a history of prior arthroscopic surgery in the ipsilateral hip, or a history of labral debridement only were excluded. Subanalysis was performed between patients undergoing no capsular closure who were propensity score matched 1:1 with patients undergoing repair or plication based on age, sex, and preoperative Modified Harris Hip Score (MHHS). We compared patients who underwent T-capsulotomy with concomitant capsular closure matched 1:5 with patients who underwent an interportal capsulotomy with concomitant capsular repair based on age, sex, and preoperative MHHS. Results Patients undergoing capsular closure (n = 1069), compared with the no-closure group (n = 230), were more often female (68.6% vs 53.0%, respectively; P < .001), were younger (36.4 ± 13.3 vs 47.9 ± 14.7 years; P < .001), and had superior MHHS scores at 2 years postoperatively (85.8 ± 14.5 vs 81.8 ± 18.4, respectively; P = .020). In the matched analysis, no difference was found in outcome measures between patients in the capsular closure group (n = 215) and the no-closure group (n = 215) at any follow-up timepoint. No significant difference was seen between the 2 closure techniques at any follow-up timepoint. Patients with closure of the capsule achieved the minimal clinically important difference (MCID) and the patient acceptable symptom state (PASS) for the 1-year MHHS at a similar rate as those without closure (MCID, 50.3% vs 44.9%, P = .288; PASS, 56.8% vs 51.1%, P = .287, respectively). Patients with T-capsulotomy achieved the MCID and the PASS for the 1-year MHHS at a similar rate compared with those with interportal capsulotomy (MCID, 50.1% vs 44.9%, P = .531; PASS, 65.7% vs 61.2%, P = .518, respectively). Conclusion When sex, age, and preoperative MHHS were controlled, capsular closure and no capsular closure after arthroscopic hip labral repair were associated with similar pain and functional outcomes for patients up to 2 years postoperatively.

Outcomes of Biceps Tenodesis Variations With Concomitant Rotator Cuff Repair: A Multicenter Database Analysis. Orthop J Sports Med 2023; 11:23259671231180173. [PMID: 37359975 PMCID: PMC10288396 DOI: 10.1177/23259671231180173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 03/09/2023] [Indexed: 06/28/2023] Open
Abstract
Background Studies to date comparing biceps tenodesis methods in the setting of concomitant rotator cuff repair (RCR) have demonstrated relatively equivalent pain and functional outcomes. Purpose To compare biceps tenodesis constructs, locations, and techniques in patients who underwent RCR using a large multicenter database. Study Design Cohort study; Level of evidence, 3. Methods A global outcome database was queried for patients with medium- and large-sized tears who underwent biceps tenodesis with RCR between 2015 and 2021. Patients ≥18 years of age with a minimum follow-up of 1 year were included. The American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, visual analog scale for pain, and Veterans RAND 12-Item Health Survey (VR-12) scores were compared at 1 and 2 years of follow-up based on construct (anchor, screw, or suture), location (subpectoral, suprapectoral, or top of groove), and technique (inlay or onlay). Nonparametric hypothesis testing was used to compare continuous outcomes at each time point. The proportion of patients achieving the minimal clinically important difference (MCID) at the 1- and 2-year follow-ups were compared between groups using chi-square tests. Results A total of 1903 unique shoulder entries were analyzed. Improvement in VR-12 Mental score favored anchor and suture fixations at 1 year of follow-up (P = .042) and the onlay tenodesis technique at 2 years of follow-up (P = .029). No additional tenodesis comparisons demonstrated statistical significance. The proportion of patients with improvement exceeding the MCID did not differ based on tenodesis methods for any outcome score assessed at the 1- or 2-year follow-up. Conclusion Biceps tenodesis with concomitant RCR led to improved outcomes regardless of tenodesis fixation construct, location, or technique. A clear optimal tenodesis method with RCR remains to be determined. Surgeon preference and experience with various tenodesis methods as well as patient clinical presentation should continue to guide surgical decision-making.

Abstract
CASE We report the second-known case of subacromial-subdeltoid bursitis with rice bodies after rotator cuff repair with a Smith + Nephew REGENETEN bovine-derived bioinductive collagen scaffold implant. After the removal of rice bodies and a portion of implant that had not incorporated, the patient recovered well and made a full return to work and recreational activities. CONCLUSION This case demonstrates that persistent pain, swelling, or decreased range of motion for several months after rotator cuff repair with the use of a collagen implant may warrant a relatively early magnetic resonance imaging to evaluate for underlying pathology. It also provides a framework for physicians who may see similar patients in the future.

Outcomes of Biceps Tenotomy Versus Tenodesis During Arthroscopic Rotator Cuff Repair: An Analysis of Patients From a Large Multicenter Database. Orthop J Sports Med 2022; 10:23259671221110851. [PMID: 35859647 PMCID: PMC9290127 DOI: 10.1177/23259671221110851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 05/12/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Studies to date evaluating biceps tenotomy versus tenodesis in the setting of concomitant rotator cuff repair (RCR) have demonstrated relatively equivalent pain and functional outcomes. Hypothesis: It was hypothesized that a significant difference could be demonstrated for pain and functional outcome scores comparing biceps tenotomy versus tenodesis in the setting of RCR if the study was adequately powered. Study Design: Cohort study; Level of evidence, 3. Methods: The Arthrex Surgical Outcomes System database was queried for patients who underwent arthroscopic biceps tenotomy or tenodesis and concomitant RCR between 2013 and 2021; included patients had a minimum of 2 years of follow-up. Outcomes between treatment types were assessed using the American Shoulder and Elbow Surgeons Shoulder (ASES), Single Assessment Numeric Evaluation (SANE), visual analog scale (VAS) for pain, and Veterans RAND 12-Item Health Survey (VR-12) scores preoperatively and at 3 months, 6 months, 1 year, and 2 years postoperatively. Results were stratified by age at surgery (3 groups: <55, 55-65, >65 years) and sex. Results: Overall, 1936 primary RCRs were included for analysis (1537 biceps tenodesis and 399 biceps tenotomy patients). Patients who underwent tenotomy were older and more likely to be female. A greater proportion of female patients aged <55 years and 55 to 65 years received a biceps tenotomy compared with tenodesis (P = .012 and .026, respectively). All scores were comparable between the treatment types preoperatively and at 3 months, 6 months, and 1 year postoperatively. At 2-year follow-up, patients who received a biceps tenodesis had statistically more favorable ASES, SANE, VAS pain, and VR-12 scores (P ≤ .031); however, the differences did not exceed the minimal clinically important difference (MCID) for these measures. Conclusion: Our findings indicate that surgeons are more likely to perform a biceps tenotomy in female and older patients. Biceps tenodesis provided improved pain and functional scores compared with tenotomy at 2-year follow-up; however, the benefit did not exceed previously reported MCID for the outcome scores. Both procedures provided improvement in outcomes; thus, the choice of procedure should be a shared decision between the surgeon and patient.

Abstract
Background The purpose of this study is to present surgical outcomes after humeral head allograft augmentation and glenoid-based procedures in patients with active, uncontrolled seizure activity and anterior shoulder instability. Methods A retrospective review of a surgical database for patients with active seizure disorder and with recurrent shoulder instability managed with humeral head augmentation was performed. All patients underwent surgical intervention. Postoperative outcomes including Shoulder Pain and Disability Index, Simple Shoulder Test, American Shoulder and Elbow Surgeons questionnaire, and the Short Form Health Survey (SF-12) were recorded at a minimum of 2 years. We hypothesized that appropriate management of the bony defects in these bipolar injuries would result in low recurrence and satisfactory outcomes. Results Ten patients including 8 males and 2 females (15 shoulders) with active seizure-related shoulder instability underwent surgical intervention including allograft bone grafting of the Hill-Sachs lesion for anterior shoulder instability. The average age was 27 years. All patients reported recurrent seizures postoperatively, but only one sustained a shoulder dislocation after surgery that was unrelated to seizure activity. Self-reported satisfaction was “much better” or “better” in 92% of shoulders. Average outcome scores were as follows: American Shoulder and Elbow Surgeons score = 67 (33-100), Shoulder Pain and Disability Index = 32.5 (0-83), Simple Shoulder Test = 9.4 (5-12), SF-12 PCS = 44.1 (21-65), and SF-12 MCS = 50.6 (21-61). The average follow-up was 4.8 years. Conclusion Management of bipolar shoulder injuries with humeral head allograft augmentation and glenoid based surgery leads to low recurrence rates and good clinical outcomes in patients with uncontrolled, seizure-related shoulder instability.

Biopsychosocial Influence on Shoulder Pain: Influence of Genetic and Psychological Combinations on Twelve-Month Postoperative Pain and Disability Outcomes. Arthritis Care Res (Hoboken) 2016; 68:1671-1680. [PMID: 26945673 DOI: 10.1002/acr.22876] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2015] [Revised: 12/10/2015] [Accepted: 02/23/2016] [Indexed: 01/25/2023]
Abstract
OBJECTIVE To identify novel combinations of genetic and psychological factors that predicted 12-month postoperative pain and disability outcomes following arthroscopic shoulder surgery. METHODS A prospective presurgical cohort (n = 150) was recruited to complete validated psychological questionnaires and have their DNA collected from saliva. DNA was genotyped for a priori selected genes involved with pain modulation (ADRB2, OPRM1, AVPR1A, GCH1, and KCNS1) and inflammation (IL1B, TNF/LTA, and IL6). The outcome measures of interest were the Brief Pain Inventory and Disabilities of the Arm, Shoulder, and Hand questionnaire. Followup for the cohort was at 3, 6, and 12 months postoperatively. After controlling for age, sex, race, and preoperative status, genetic and psychological factors were entered as main effects and interaction terms in separate general linear models for predicting postoperative pain and disability outcomes. RESULTS Seven interactions involving pain-modulatory genes were identified. Three provided strong statistical evidence for different outcomes, including KCNS1 and kinesiophobia for preoperative pain intensity, ADRB2 and depressive symptoms for postoperative course, and GCH1 and anxiety symptoms for 12-month pain-intensity outcome. Ten interactions involving inflammatory genes were identified. Three provided strong statistical evidence for the 12-month postoperative course outcome, including 2 different IL6 single-nucleotide polymorphism and pain catastrophizing, and IL6 and depressive symptoms. CONCLUSION The current study identified novel genetic and psychological interactions that can be used in future studies to further understand the development of persistent postoperative pain and investigate the effectiveness of tailored treatment.

Abstract
Background There is limited literature investigating preoperative physical therapy (pre-op PT) treatment on pain intensity and disability after musculoskeletal surgery. The purposes of the present cohort study were to describe patient characteristics for those who had and did not have pre-op PT treatment and determine whether pre-op PT influenced the length of postoperative physical therapy (post-op PT) treatment (number of sessions) and 3-month and 6-month postsurgical outcomes, such as pain intensity and disability. Patients and methods A total of 124 patients (mean age =43 years, 81 males) with shoulder pain were observed before and after shoulder arthroscopic surgery. Demographic data, medical history, and validated self-report questionnaires were collected preoperatively and at 3 months and 6 months after surgery. Analysis of variance models were performed to identify differences across measures for patients who had pre-op PT treatment and those who did not and to examine outcome differences at 3 months and 6 months. Alpha was set at the 0.05 level for statistical significance. Results Males had less participation in pre-op PT than females (P=0.01). In contrast, age, pain intensity, disability, and pain-associated psychological factors did not differ between pre-op PT treatment groups (P>0.05). Subacromial bursectomies were more commonly performed in patients having pre-op PT treatment (P<0.05). Pre-op PT treatment did not influence length of post-op PT treatment and did not affect 3-month and 6-month pain intensity and disability outcomes. Differences in distribution of pre-op PT for males and females and subacromial bursectomy did not influence 3-month or 6-month postsurgical outcomes. Conclusion Receiving pre-op PT treatment did not influence post-op PT treatment or pain and disability outcomes at 3 months and 6 months. This prospective cohort study provides no evidence of benefit for pre-op PT on post-op PT treatment or postsurgical outcomes. Females or patients receiving certain surgical procedures are more likely to undergo pre-op PT treatment. However, these differences did not influence postoperative outcomes in this cohort.

Abstract
BACKGROUND Plyometric exercise is used during rehabilitation after anterior cruciate ligament (ACL) reconstruction to facilitate the return to sports participation. However, clinical outcomes have not been examined, and high loads on the lower extremity could be detrimental to knee articular cartilage. PURPOSE To compare the immediate effect of low- and high-intensity plyometric exercise during rehabilitation after ACL reconstruction on knee function, articular cartilage metabolism, and other clinically relevant measures. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Twenty-four patients who underwent unilateral ACL reconstruction (mean, 14.3 weeks after surgery; range, 12.1-17.7 weeks) were assigned to 8 weeks (16 visits) of low- or high-intensity plyometric exercise consisting of running, jumping, and agility activities. Groups were distinguished by the expected magnitude of vertical ground-reaction forces. Testing was conducted before and after the intervention. Primary outcomes were self-reported knee function (International Knee Documentation Committee [IKDC] subjective knee form) and a biomarker of articular cartilage degradation (urine concentrations of crosslinked C-telopeptide fragments of type II collagen [uCTX-II]). Secondary outcomes included additional biomarkers of articular cartilage metabolism (urinary concentrations of the neoepitope of type II collagen cleavage at the C-terminal three-quarter-length fragment [uC2C], serum concentrations of the C-terminal propeptide of newly formed type II collagen [sCPII]) and inflammation (tumor necrosis factor-α), functional performance (maximal vertical jump and single-legged hop), knee impairments (anterior knee laxity, average knee pain intensity, normalized quadriceps strength, quadriceps symmetry index), and psychosocial status (kinesiophobia, knee activity self-efficacy, pain catastrophizing). The change in each measure was compared between groups. Values before and after the intervention were compared with the groups combined. RESULTS The groups did not significantly differ in the change of any primary or secondary outcome measure. Of interest, sCPII concentrations tended to change in opposite directions (mean ± SD: low-intensity group, 28.7 ± 185.5 ng/mL; high-intensity group, -200.6 ± 255.0 ng/mL; P = .097; Cohen d = 1.03). Across groups, significant changes after the intervention were increased the IKDC score, vertical jump height, normalized quadriceps strength, quadriceps symmetry index, and knee activity self-efficacy and decreased average knee pain intensity. CONCLUSION No significant differences were detected between the low- and high-intensity plyometric exercise groups. Across both groups, plyometric exercise induced positive changes in knee function, knee impairments, and psychosocial status that would support the return to sports participation after ACL reconstruction. The effect of plyometric exercise intensity on articular cartilage requires further evaluation. REGISTRATION NUMBER Clinicaltrials.gov NCT01851655.

Failure of Anterior Cruciate Ligament Reconstruction. THE ARCHIVES OF BONE AND JOINT SURGERY 2015; 3:220-240.

Abstract
The present review classifies and describes the multifactorial causes of anterior cruciate ligament (ACL) surgery failure, concentrating on preventing and resolving such situations. The article particularly focuses on those causes that require ACL revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. Although primary ACL reconstruction has satisfactory outcome rates as high as 97%, it is important to identify the causes of failure, because satisfactory outcomes in revision surgery can drop to as much as 76%. It is often possible to identify a primary or secondary cause of ACL surgery failure; even the most meticulous planning can give rise to unexpected findings during the intervention. The adopted protocol should therefore be sufficiently flexible to adapt to the course of surgery. Preoperative patient counseling is essential. The surgeon should limit the patient's expectations for the outcome by explaining the complexity of this kind of procedure. With adequate preoperative planning, close attention to details and realistic patient expectations, ACL revision surgery may offer beneficial and satisfactory results for the patient.

Abstract
Tailored treatment based on individual risk factors is an area with promise to improve options for pain relief. Musculoskeletal pain has a biopsychosocial nature, and multiple factors should be considered when determining risk for chronic pain. This study investigated whether subgroups comprised genetic and psychological factors predicted outcomes in preclinical and clinical models of shoulder pain. Classification and regression tree analysis was performed for an exercise-induced shoulder injury cohort (n = 190) to identify high-risk subgroups, and a surgical pain cohort (n = 150) was used for risk validation. Questionnaires for fear of pain and pain catastrophizing were administered before injury and preoperatively. DNA collected from saliva was genotyped for a priori selected genes involved with pain modulation (COMT and AVPR1A) and inflammation (IL1B and TNF/LTA). Recovery was operationalized as a brief pain inventory rating of 0/10 for current pain intensity and <2/10 for worst pain intensity. Follow-up for the preclinical cohort was in daily increments, whereas follow-up for the clinical cohort was at 3, 6, and 12 months postoperatively. Risk subgroups comprised the COMT high pain sensitivity variant and either pain catastrophizing or fear of pain were predictive of heightened shoulder pain responses in the preclinical model. Further analysis in the clinical model identified the COMT high pain sensitivity variant and pain catastrophizing subgroup as the better predictor. Future studies will determine whether these findings can be replicated in other anatomical regions and whether personalized medicine strategies can be developed for this risk subgroup.

Abstract
BACKGROUND Shoulder pain and surgery are common among older adults. However, the extent to which older age affects recovery after shoulder surgery is not well understood. OBJECTIVE To assess influence of older age on postoperative recovery factors 3 and 6 months after shoulder arthroscopy. DESIGN Prospective cohort study. SETTING University-affiliated outpatient orthopedic surgical center. PATIENTS A convenience sample of 139 persons between 20 and 79 years of age who experienced shoulder pain, had musculoskeletal dysfunction based on imaging and physician assessment, and were scheduled for an arthroscopic shoulder procedure. MAIN OUTCOME MEASURES Postoperative outcomes were compared among younger, middle-aged, and older adults before surgery and at 3 and 6 months after surgery using analysis of variance modeling. Movement-evoked pain and an experimental laboratory correlate of pain processing were assessed at each time point. The influence of older age on 3- and 6-month pain outcomes were determined via multivariate regression analyses after accounting for preoperative, intraoperative, and postoperative prognostic factors. RESULTS Older adults had higher movement-evoked pain intensity (F2,108 = 5.18, P = .007) and experimental pain response (F2,111 = 7.24, P = .001) at 3 months compared with young and middle-aged adults. After controlling for key prognostic factors, older age remained a positive predictor of 3-month movement-evoked pain (R(2) = 0.05; standardized [St.] β = 0.263, P = .031) and experimental pain response (R(2) = 0.07; St. β = 0.295, P = .014). Further, older age remained a positive predictor of movement-evoked pain at 6 months (R(2) = 0.04; St. β = 0.231, P = .004), despite no age group differences in outcome. Older age was found to be the strongest predictor of 3- and 6-month movement-evoked pain. CONCLUSION Older adults may experience more pain related to movement, as well as endogenous pain excitation, in the first few months after shoulder arthroscopy. Future age-related research should consider use of movement-evoked pain intensity and experimental pain response as pain outcomes, as well as the utility of such measures in clinical care.

Abstract
BACKGROUND Adaptations in hip range of motion (ROM) and strength have been shown to influence performance and injury risk in overhead athletes. These adaptations in hip ROM and strength have not been examined longitudinally, and little is known regarding whether these changes are a result of pitching workload. HYPOTHESIS/PURPOSE The authors hypothesized that hip rotation ROM and strength would change over the course of a season, and would be associated with pitching workload (number of pitches over the course of a season). The purpose of this exploratory, pilot study was twofold: 1) to examine changes in hip external rotation (ER) ROM, internal rotation (IR) ROM, isometric hip abduction and hip extension strength in pitchers occurring over the course of a competitive season, and 2) to determine the association between changes in hip ROM, strength, and pitching volume. STUDY DESIGN Cohort (longitudinal) study. METHODS Bilateral hip rotation ROM and hip isometric strength was tested pre- and post-season in fourteen collegiate baseball pitchers. Pearson correlations were calculated to determine the association between changes in hip ROM, strength, and pitching workload. RESULTS Trail and lead hip ER, trail and lead hip total rotational ROM, and trail and lead hip abduction strength in all pitchers decreased from preseason to postseason (p < 0.01). However, these changes were not significantly associated with pitching workload (p > 0.05). CONCLUSION This study demonstrates that changes occur in hip ROM and strength in collegiate pitchers over the course of a season. These changes were not associated with pitching workload.

Abstract
BACKGROUND Fear of reinjury and lack of confidence influence return-to-sport outcomes after anterior cruciate ligament (ACL) reconstruction. The physical, psychosocial, and functional recovery of patients reporting fear of reinjury or lack of confidence as their primary barrier to resuming sports participation is unknown. PURPOSE To compare physical impairment, functional, and psychosocial measures between subgroups based on return-to-sport status and fear of reinjury/lack of confidence in the return-to-sport stage and to determine the association of physical impairment and psychosocial measures with function for each subgroup at 6 months and 1 year after surgery. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Physical impairment (quadriceps index [QI], quadriceps strength/body weight [QSBW], hamstring:quadriceps strength ratio [HQ ratio], pain intensity), self-report of function (International Knee Documentation Committee [IKDC]), and psychosocial (Tampa Scale for Kinesiophobia-shortened form [TSK-11]) measures were collected at 6 months and 1 year after surgery in 73 patients with ACL reconstruction. At 1 year, subjects were divided into "return-to-sport" (YRTS) or "not return-to-sport" (NRTS) subgroups based on their self-reported return to preinjury sport status. Patients in the NRTS subgroup were subcategorized as NRTS-Fear/Confidence if fear of reinjury/lack of confidence was the primary reason for not returning to sports, and all others were categorized as NRTS-Other. RESULTS A total of 46 subjects were assigned to YRTS, 13 to NRTS-Other, and 14 to NRTS-Fear/Confidence. Compared with the YRTS subgroup, the NRTS-Fear/Confidence subgroup was older and had lower QSBW, lower IKDC score, and higher TSK-11 score at 6 months and 1 year; however, they had similar pain levels. In the NRTS-Fear/Confidence subgroup, the IKDC score was associated with QSBW and pain at 6 months and QSBW, QI, pain, and TSK-11 scores at 1 year. CONCLUSION Elevated pain-related fear of movement/reinjury, quadriceps weakness, and reduced IKDC score distinguish patients who are unable to return to preinjury sports participation because of fear of reinjury/lack of confidence. Despite low average pain ratings, fear of pain may influence function in this subgroup. Assessment of fear of reinjury, quadriceps strength, and self-reported function at 6 months may help identify patients at risk for not returning to sports at 1 year and should be considered for inclusion in return-to-sport guidelines.

Abstract
To examine whether anchors used in arthroscopic Bankart repair increased the risk of subsequent fracture, six intact polyurethane scapulae and six with three 3.0-mm suture anchors placed along the anteroinferior glenoid were compared. An axial load of 1 mm/s was applied to the anteroinferior glenohumeral joint with a prosthetic humeral head. Outcome measures were force needed for initial fracture and catastrophic failure, percent of anterior glenoid bone loss, and fracture length. With the numbers available, no significant differences could be detected between groups in yield load or maximum load. The anchor group had a significantly larger percentage of bone loss (p < .01) and fracture length (p < .01) compared to the intact group. In this study, anchors did not decrease force needed to fracture but did lead to significantly larger fractures of the anterior glenoid during a simulated dislocation event. Further study using various anchors and techniques is warranted.

Urinary CTX-II concentrations are elevated and associated with knee pain and function in subjects with ACL reconstruction. Osteoarthritis Cartilage 2012; 20:1294-301. [PMID: 22863613 PMCID: PMC3878437 DOI: 10.1016/j.joca.2012.07.014] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2012] [Revised: 07/03/2012] [Accepted: 07/18/2012] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Post-traumatic knee osteoarthritis (OA) is prevalent after anterior cruciate ligament reconstruction (ACLR). Biomarkers that identify individuals likely to develop OA, especially symptomatic OA, can help target preventative and therapeutic strategies. This study examined the magnitude and change over time in urinary CTX-II (uCTX-II) concentrations shortly after ACL reconstruction, and, secondarily, the associations with knee pain and function. DESIGN Subjects were 28 patients with ACLR and 28 age- and sex-matched controls (CNTRL). Testing was conducted at four time points spaced 4 weeks apart (4, 8, 12 and 16 weeks post-operative in ACLR). Measures included demographics, urine samples, Numeric Pain Rating Scale (NPRS) and International Knee Documentation Committee Subjective Knee Form (IKDC-SKF). uCTX-II concentrations were determined with competitive enzyme-linked immunosorbent assay (ELISA). uCTX-II concentrations at each time point in ACLR were compared to the mean concentration over time in CNTRL, with and without adjustment for body mass index (BMI). Changes over time in each measure and correlations between the slopes of change were examined. RESULTS uCTX-II concentrations were significantly higher in ACLR than CNTRL through 16 weeks post-operative when adjusted for BMI. In ACLR, uCTX-II concentrations significantly decreased over time, and the slope was associated with NPRS (r = 0.406, P = 0.039) and IKDC-SKF (r = -0.402, P = 0.034) slopes. CONCLUSION uCTX-II concentrations shortly after ACLR were elevated compared to CNTRL and declined over time. Decreasing uCTX-II concentrations were associated with decreasing knee pain and improving function. uCTX-II may have a role as a prognostic marker following ACLR and warrants further investigation.

Abstract
BACKGROUND Many individuals do not resume unrestricted, preinjury sports participation after anterior cruciate ligament reconstruction, thus a better understanding of factors associated with function is needed. The purpose of this study was to investigate the association of knee impairment and psychological variables with function in subjects with anterior cruciate ligament reconstruction. HYPOTHESIS After controlling for demographic variables, knee impairment and psychological variables contribute to function in subjects with anterior cruciate ligament reconstruction. STUDY DESIGN Cross-sectional study; Level of evidence, 4a. METHODS Fifty-eight subjects with a unilateral anterior cruciate ligament reconstruction completed a standardized testing battery for knee impairments (range of motion, effusion, quadriceps strength, anterior knee joint laxity, and pain intensity), kinesiophobia (shortened Tampa Scale for Kinesiophobia), and function (International Knee Documentation Committee subjective form and single-legged hop test). Separate 2-step regression analyses were conducted with International Knee Documentation Committee subjective form score and single-legged hop index as dependent variables. Demographic variables were entered into the model first, followed by knee impairment measures and Tampa Scale for Kinesiophobia score. RESULTS A combination of pain intensity, quadriceps index, Tampa Scale for Kinesiophobia score, and flexion motion deficit contributed to the International Knee Documentation Committee subjective form score (adjusted r(2) = 0.67; P < .001). Only effusion contributed to the single-legged hop index (adjusted r(2) = 0.346; P = .002). CONCLUSION Knee impairment and psychological variables in this study were associated with self-report of function, not a performance test. CLINICAL RELEVANCE The results support focusing anterior cruciate ligament reconstruction rehabilitation on pain, knee motion deficits, and quadriceps strength, as well as indicate that kinesiophobia should be addressed. Further research is needed to reveal which clinical tests are associated with performance testing.

Abstract
The purpose of this study was to investigate glenohumeral translation in-vivo during active shoulder abduction in the scapular plane. Three-dimensional (3D) models of 9 shoulders were created from CT scans. Fluoroscopic views aligned to the plane of the scapula were recorded during active arm abduction with neutral rotation. 3D motions were determined using model-based 3D-to-two-dimensional (2D) registration. Humeral translation was referenced to the glenoid center in the superior/inferior direction. The humerus moved an average of 1.7 mm superior with arm abduction, from an inferior location to the glenoid center. The humeral head was centered within 1 mm from the glenoid center above 80 degrees abduction. Variability in glenohumeral translation between shoulders decreased significantly from initial to final arm abduction. Our findings agree with some authors' observations of inferior-to-central translation of the humerus and behavior as a congruent ball and socket. We believe this information will help improve the understanding of shoulder function.

Evidence for a biopsychosocial influence on shoulder pain: pain catastrophizing and catechol-O-methyltransferase (COMT) diplotype predict clinical pain ratings. Pain 2007; 136:53-61. [PMID: 17686583 PMCID: PMC2669670 DOI: 10.1016/j.pain.2007.06.019] [Citation(s) in RCA: 127] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2007] [Revised: 05/11/2007] [Accepted: 06/15/2007] [Indexed: 11/29/2022]
Abstract
The experience of pain is believed to be influenced by social, cultural, environmental, psychological, and genetic factors. Despite this assertion, few studies have included clinically relevant pain phenotypes when investigating interactions among these variables. This study investigated whether psychological variables specific to fear-avoidance models and catechol-O-methyltransferase (COMT) genotype influenced pain ratings for a cohort of patients receiving operative treatment of shoulder pain. Patients (n=58) completed questionnaires and had COMT genotype determined pre-operatively. Then, shoulder pain ratings were collected 3-5 months post-operatively. This cohort consisted of 24 females and 34 males, with mean age of 50.3 (SD=15.0) and pre-operative pain rating of 4.5/10 (SD=1.8). The frequency of COMT diplotypes was 34 with "high COMT activity" (LPS group) and 24 with "low COMT activity" (APS/HPS group). Preliminary analysis indicated that of all the fear-avoidance variables considered (fear of pain, kinesiophobia, pain catastrophizing, and anxiety), only pain catastrophizing was a unique contributor to clinical pain ratings. A hierarchical regression model indicated that an interaction between pain catastrophizing and COMT diplotype contributed additional variance in pre-operative pain ratings. The pain catastrophizingxCOMT diplotype interaction demonstrated predictive validity as patients with high pain catastrophizing and low COMT activity (APS/HPS group) were more likely (RR=6.8, 95% CI=2.8-16.7) to have post-operative pain ratings of 4.0/10 or higher. Our findings suggest that an interaction between pain catastrophizing and COMT diplotype has the potential to influence pain ratings in patients seeking operative treatment of their shoulder pain.

Abstract
The discoid menisci is a common abnormalitiy of the knee seen by pediatric and general orthopaedists. This aberration of the fibrocartilaginous meniscus can occur medially, but is most common on the lateral side. Because of unusual biomechanical stresses, all discoid menisci are at increased risk for meniscal tears. Types I and II variations have a disc-shaped meniscus, which cover more of the tibial plateau than normal and may be of increased thickness. Both have normal attachment to the tibial plateau and do not require treatment when asymptomatic. The Wrisberg or Type III variant may not be abnormal in shape. It lacks posterior attachment to the tibia resulting in a hypermobile meniscus. The knee may snap or pop when flexed and lock in extension; pain is a common presenting complaint. Radiographs can aid diagnosis, but frequently are not definitive. Identification of discoid menisci and associated meniscal tears can be accomplished with magnetic resonance imaging. Where no tear exists and the meniscus is normal in shape, diagnosis may be more difficult. Presented here is a case of a discoid lateral meniscus not observable on initial magnetic resonance images but visible on magnetic resonance images taken while the affected knee was extended in the locked position.

Abstract
Pathology of the superior aspect of the glenoid labrum (SLAP lesion) poses a significant challenge to the rehabilitation specialist due to the complex nature and wide variety of etiological factors associated with these lesions. A thorough clinical evaluation and proper identification of the extent of labral injury is important to determine the most appropriate nonoperative and/or surgical management. Postoperative rehabilitation is based on the specific surgical procedure as well as the extent, location, and mechanism of labral pathology and associated lesions. Emphasis is placed on protecting the healing labrum, while gradually restoring range of motion, strength, and dynamic stability of the glenohumeral joint. The purpose of this paper is to provide an overview of the anatomy and pathomechanics of SLAP lesions and review specific clinical examination techniques used to identify these lesions, including 3 newly described tests. Furthermore, a review of the current surgical management and postoperative rehabilitation guidelines is provided.
