Golf participation after rotator cuff repair: functional outcomes, rate of return and factors associated with return to play.

BACKGROUND: Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. METHODS: Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. RESULTS: Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). CONCLUSIONS: Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf. Level of evidence: Level IV.

Midterm results of stemless impaction shoulder arthroplasty for primary osteoarthritis: a prospective, multicenter study.

Background: Stemless shoulder arthroplasty using 4 open-fin press-fit anchors has been showing promising short-term clinical and radiographic results for patients' primary osteoarthritis. This prospective, multicenter study presents 5-year postoperative clinical and radiological outcomes of a stemless shoulder arthroplasty for primary osteoarthritis. Methods: Between November 2012 and December 2015, 100 patients were treated for primary osteoarthritis with the Sidus stem-free shoulder system at 7 European centers. Clinical assessment included the Constant-Murley Score, American Shoulder and Elbow Standardized Shoulder Assessment Form score, Subjective Shoulder Value, and range of motion. True anteroposterior, axial and lateral radiographs were reviewed for osteolysis, glenoid and humerus loosening, heterotopic ossification, radiolucent lines, component migration and humeral bone resorption. In addition to a Kaplan-Meier survival analysis, a comparative analysis between total shoulder arthroplasty and hemiarthroplasty was performed. Results: Seventy-one patients (36 females) with a mean age of 63.8 years (range: 47-79 years) were available for the 5-year clinical and radiographic follow-up (range: 52-79 months). There was a significant increase (P < .0001) in all outcome scores compared to baseline values. Patients with total shoulder arthroplasty (n = 48) achieved significantly better functional outcome than patients with shoulder hemiarthroplasty (n = 23) with regard to the absolute and relative Constant-Murley Score, American Shoulder and Elbow Standardized Shoulder Assessment Form score, and Subjective Shoulder Value as well as greater abduction strength and range of motion in forward elevation and external rotation (P ≤ .004). There were no cases of osteolysis or humeral loosening. There were some cases of heterotopic ossification (1.4%), radiolucency around the humerus (1.4%) or glenoid (25%), glenoid migration (2.1%), inferior osteophytes (1.4%) or humerus bone resorption (9.9%). The 5-year survival was 94%. Conclusion: Patients treated with the Sidus stem-free shoulder system for primary osteoarthritis continue to achieve good clinical and radiographic results without any signs of aseptic humeral implant loosening at 5 years postsurgery.

Tear size, general health status and smoking influence functional outcome at 5 years following arthroscopic rotator cuff repair.

Introduction: There is limited medium-term outcome data regarding the predictors of functional outcome and patient satisfaction after arthroscopic rotator cuff repair. Methods: 287 patients that underwent arthroscopic rotator cuff repair under a high-volume single surgeon were contacted at a minimum of 4 years following surgery. Patient demographics, tear size and co-morbidities were pre-operatively recorded. The Oxford shoulder score, EuroQol 5-dimensional score and patient satisfaction were recorded at final follow-up. Results: 234 (81.5%) patients completed follow-up at a mean of 5.5 (4-9) years. There were 126 males and 108 females with a mean age of 60 (range 25-83) years. The majority of patients (n = 211, 90%) were satisfied with their final outcome. Multivariate linear regression analysis (R 2 = 0.64) identified that increasing tear size (p = 0.04), worsening general health assessed by the EuroQol 5-Dimensional (p < 0.001), and smoking (p = 0.049) were associated with a worse Oxford shoulder score. Logistic regression analysis (R 2 = 0.13) identified that worsening general health assessed by the EuroQol 5-Dimensional (p < 0.001), and smoking (p = 0.01) were associated with an increased risk of patient dissatisfaction. Conclusion: General health status and smoking are independent predictors of functional outcome and patient satisfaction at medium-term follow-up following arthroscopic rotator cuff repair.

Functional outcome following arthroscopic repair of massive rotator cuff tears is equal to smaller rotator cuff tears: a retrospective case-control study.

Background: There is a paucity of studies comparing patient-reported outcomes of arthroscopic massive rotator cuff repairs against non-massive rotator cuff repairs. The aim of this study is to assess the Quick Disabilities of the Arm, Shoulder and Hand questionnaire and Oxford Shoulder Score at a minimum of one-year follow-up according to the size of the rotator cuff tear. Methods: A retrospective case-control study was undertaken. All patients underwent rotator cuff repairs using the same technique by a single surgeon. Quick Disabilities of the Arm, Shoulder and Hand questionnaire and Oxford Shoulder Score were collected pre-operatively and at final review with a minimum follow-up of one year. Patients with massive rotator cuff repairs were compared to patients who had non-massive rotator cuff repairs. Results: Eighty-two patients were included in the study of which 42 (51%) underwent massive rotator cuff repair. The mean follow-up period was 17.5 months. Quick Disabilities of the Arm, Shoulder and Hand questionnaire improved significantly (p < 0.001) from 46.1 pre-operatively to 15.6 at final follow-up for massive rotator cuff repairs. Oxford Shoulder Score improved significantly (p < 0.001) from 26.9 pre-operatively to 41.4 at final follow-up for massive rotator cuff repairs. There was no significant difference in the final Quick Disabilities of the Arm, Shoulder and Hand questionnaire (p = 0.35) or Oxford Shoulder Score (p = 0.45) between the groups. No revision surgery was required within the follow-up period. Conclusion: Arthroscopic massive rotator cuff repairs have comparable functional outcome to smaller rotator cuff repair in the short-term and should be considered in a selected group of patients.

Cost-effectiveness of the reverse total shoulder arthroplasty. Does indication affect outcome?

BACKGROUND: The primary aim of this study was to determine the cost-effectiveness of the reverse total shoulder arthroplasty in a prospective cohort of patients over a two-year post-operative period. METHODS: Patients who underwent reverse total shoulder arthroplasty were prospectively monitored for 24 months post-operatively using the Oxford Shoulder Score, Disabilities of the Arm, Shoulder and Hand questionnaire and EuroQol 5-dimensional questionnaire. Any complications or use of health care resources were recorded. The incremental cost-effectiveness ratio was used to express the cost per quality-adjusted life year gained. RESULTS: Sixty-seven patients were analysed, 46 primary reverse total shoulder arthroplasty for cuff arthropathy and 21 revisions from previous arthroplasty. Both indications had comparable peri-operative shoulder scores without significant difference. Using the mean change of EuroQol 5-dimensional questionnaire at one year, the incremental cost-effectiveness ratio was calculated at £16,827.43 per quality-adjusted life year, decreasing to £8313.48 per quality-adjusted life year at two years. Primary was associated with a lower incremental cost-effectiveness ratio at two years (primary £7596.76 vs. revision £11,748.51). The estimated post-operative life expectancy of the cohort was 6.9 years with a projected cost per quality-adjusted life year of £2438.78. CONCLUSIONS: Reverse total shoulder arthroplasty provides a cost-effective intervention with excellent patient outcomes at two years post-operatively.

Sidus Stem-Free Shoulder System for primary osteoarthritis: short-term results of a multicenter study.

BACKGROUND: The aim of this prospective multicenter study was to evaluate clinical and radiologic results of a new metaphyseal anchored system. This system features a different anchor geometry that potentially leads to better bony integration and less loosening. METHODS: From November 2012 until December 2015, 148 patients (151 shoulders) were treated with the Sidus Stem-Free Shoulder System at 9 centers in Europe. The main indication was primary osteoarthritis (80.1%). This analysis only includes patients diagnosed with primary osteoarthritis (n = 121). A clinical evaluation was performed using the Constant-Murley score, Subjective Shoulder Value, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, and range of motion. Radiologic assessment was based on the occurrence of radiolucent lines and signs of implant migration, osteolysis, loosening, and heterotopic ossification. RESULTS: We evaluated 105 patients after a follow-up period of 2 years. There were 53 women and 52 men. The average age was 64 years. Total shoulder arthroplasty was performed in 73 cases and hemiarthroplasty in 32. The Constant-Murley score improved from 26 points preoperatively to 70 points at 2 years' follow-up (P < .001). The Subjective Shoulder Value increased from 34% to 84% (P < .001), and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form increased from 34 points to 86 points (P < .001). Radiologically, neither migration nor loosening was found. However, radiolucent lines of 2 mm or greater could be detected around the glenoid in 2 cases, but none of them have had clinical relevance yet. The overall complication rate was 6.7%, and the revision rate was 0%. CONCLUSION: Patients with the Sidus Stem-Free Shoulder System achieve good clinical and radiologic short-term results that are comparable with the results of other stem-free shoulder implants.

Short-Term Outcome After Arthroscopic Bursectomy Debridement of Rotator Cuff Calcific Tendonopathy With and Without Subacromial Decompression: A Prospective Randomized Controlled Trial.

PURPOSE: To conduct a prospective randomized controlled trial to assess whether arthroscopic bursectomy and debridement of the calcific deposit, with or without subacromial decompression, influences the functional outcome of patients with calcific tendonitis. METHODS: During a 4-year period, 80 patients were recruited who presented to the study center with refractory calcific tendonitis of the shoulder. Forty patients were randomized to have a subacromial decompression, and 40 were randomized not to have a subacromial decompression in combination with bursectomy and arthroscopic removal of the calcific deposit. All surgery was performed by one surgeon who was blinded to the functional assessment of the patients. Patient demographics, body mass index (BMI), and length of symptoms were recorded at the time of randomization. Patients were asked to complete a pain visual analog score (VAS), short form (SF-12), disability arm shoulder and hand (DASH), and Constant score (CS) preoperatively and at 1 year postoperatively. RESULTS: There were 21 male and 59 female patients with a mean age of 49 (range, 32 to 75) years. The mean time of follow-up was 13 (range, 12 to 15) months. There were no significant differences in gender, age, BMI, length of symptoms, or preoperative outcome measures assessed between the groups. Overall, for both groups there was a significant improvement in the pain VAS (P < .001), DASH (P < .001), and CS (P < .001) at 1 year compared with preoperative scores. There were no significant differences demonstrated between the groups for improvement in the pain VAS (P = .57), DASH (P = .93), SF-12 physical component score (P = .58), or CS (P = .27) at 1 year. CONCLUSIONS: This study has demonstrated that the short-term functional outcome of patients with calcific tendonitis after arthroscopic bursectomy and debridement of the calcific deposit is not influenced if performed in combination with or without a subacromial decompression. LEVEL OF EVIDENCE: Level I therapeutic study, randomized controlled trial.

Subacromial impingement syndrome in a patient with hereditary multiple exostosis: a case report.

BACKGROUND: Hereditary multiple exostosis (HME) is characterised by multiple osteochondromas that are distributed throughout the skeleton, invariably involving the shoulder girdle. Tumours within the subacromial space can cause secondary irritation of the rotator cuff and result in subacromial impingement syndrome. CASE PRESENTATION: We describe a 19 year old female patient with HME who presented with subacromial impingement syndrome secondary to a benign exostosis originating from the spine of the scapular and projecting into the subacromial space. CONCLUSION: The unique aspects of this report was that the origin of the exostosis, which was not observed on early standard radiographs of the shoulder, and the use of arthroscopic excision of the exostosis. Hence we believe a low threshold for additional imaging, such as a magnetic resonance imaging, should be considered for patients with HME with subacromial impingement syndrome to ensure a symptomatic exostosis is not neglected. Arthroscopic excision of a benign subacromial exostosis is effective, offering a minimally invasive approach with relief of the patient's symptoms.

Management of degenerative rotator cuff tears: a review and treatment strategy.

The aim of this review was to present an over view of degenerative rotator cuff tears and a suggested management protocol based upon current evidence. Degenerative rotator cuff tears are common and are a major cause of pain and shoulder dysfunction. The management of these tears is controversial, as to whether they should be managed non-operatively or operatively. In addition when operative intervention is undertaken, there is question as to what technique of repair should be used. This review describes the epidemiology and natural history of degenerative rotator cuff tears. The management options, and the evidence to support these, are reviewed. We also present our preferred management protocol and method, if applicable, for surgical fixation of degenerative rotator cuff tears.

Arthroscopic repair of full-thickness rotator cuff tears using bioabsorbable tacks.

PURPOSE: The purpose of this study was to evaluate the clinical results of bioabsorbable tacks (Suretac; Smith & Nephew Endoscopy, Mansfield, MA) for the arthroscopic repair of full-thickness rotator cuff tears. TYPE OF STUDY: Prospective case series. METHODS: A prospective clinical review was performed on 53 patients (38 men, 15 women) with full-thickness rotator cuff tears repaired arthroscopically using bioabsorbable tacks. Minimum follow-up was 24 months and patients were evaluated using preoperative and postoperative American Shoulder and Elbow Society (ASES) scores and Short-Form 36 Health Surveys (SF-36). A Constant and Murley score was performed at a minimum of 2 years postoperatively. RESULTS: The average patient age was 51 years (range, 23 to 74 years) and the average time for review was 29 months (range, 24 to 60 months). The average size of rotator cuff tears measured 2.5 cm (range, 1 to 5 cm) and an average of 2 Suretacs (range, 1 to 4) were used for the repair. Ten patients had tears larger than 3 cm and 5 patients had tears that measured 5 cm or larger. The average total score according to the ASES shoulder index improved from 33 to 85 points. The average score for pain improved from 6.9 to 1.3 points. The score for function improved from 11 to 25 points. These results were statistically significant (P < 0.01). There was a significant improvement in all components of the SF-36 survey. The average postoperative Constant score was 87 with the pain component measuring 12 points, range of movement 38 points, and power 21 points. CONCLUSIONS: Arthroscopic repair of full-thickness rotator cuff tears using bioabsorbable tacks produces satisfactory outcomes with regard to objective orthopaedic criteria as well as overall patient satisfaction in terms of pain relief and function. Arthroscopic rotator cuff repairs are technically demanding procedures. The use of tacks facilitates this procedure without any apparent deterioration in clinical results. LEVEL OF EVIDENCE: Level IV, case series.

Thermal capsular shrinkage for treatment of multidirectional instability of the shoulder.

BACKGROUND: Capsular laxity is the main pathology in patients with multidirectional instability, and thermal shrinkage has been commonly employed to treat this condition. The objective of this study was to evaluate thermal capsular shrinkage as a treatment of multidirectional instability of the shoulder. METHODS: Nineteen consecutive patients with multidirectional instability were treated with thermal shrinkage. Fifteen patients had involuntary instability, and four had voluntary instability. The predominant direction of the instability was anteroinferior in ten patients and posterior in five; four patients had instability in multiple directions. Patients were followed for a minimum of two years or until surgical failure and recurrence of symptoms. Postoperatively, the patients wore a sling for three weeks, and they were evaluated regularly at three, six, and twelve months. The Western Ontario Shoulder Instability Index as well as subjective and objective evaluations of the patient's function, range of motion, pain, and instability were used as clinical outcome measures. RESULTS: Nine patients had recurrence of the instability at an average of nine months (range, seven to fourteen months) following the surgical procedure. Four patients had sensory dysesthesias in the axillary nerve distribution, and one of them had deltoid weakness. All neurological symptoms resolved within nine months. The surgical procedure failed in the five patients with predominantly posterior instability. It failed in only two of the ten patients with predominantly anteroinferior instability, and overall this group had objective improvement. CONCLUSIONS: Thermal capsular shrinkage used to treat multidirectional instability had a substantial failure rate with associated postoperative complications, including recurrence of instability (nine of the nineteen patients), stiffness (five patients), and neurological symptoms (four patients).
