Long-term results of revision rotator cuff repair for failed cuff repair: a minimum 10-year follow-up study.

HYPOTHESIS: Rotator cuff repair remains associated with high retear rates, which range from 13% to 79%. The objective of this study was to evaluate the long-term clinical and structural results after revision rotator cuff repair at a minimum 10-year follow-up. METHODS: We retrospectively studied the records of all patients who underwent revision rotator cuff repair in 3 different institutions between July 2001 and December 2007 with a minimum 10-year follow-up. A total of 54 patients (61% males, mean age 52 ± 6 years old) met the inclusion criteria. Outcome measures included pain (visual analog scale [VAS]), range of motion (ROM), Subjective Shoulder Value (SSV), and the Constant score. Superior migration, osteoarthritis, and acromiohumeral interval (AHI) were assessed on standard radiographs. Fatty infiltration and structural integrity of the repaired tendon were evaluated on magnetic resonance imaging or computed tomographic arthrogram. RESULTS: At a mean 14.1 years (10.4-20.5), range of motion did not progress significantly in elevation and internal rotation between pre- and postoperation (158° [range, 100°-180°] to 164° [range, 60°-180°], P = .33, and L3 [range, sacrum-T12] to T12 [range, buttocks-T7], P = .34, respectively) and decreased in active external rotation from 45° (range, 10°-80°) to 39° (range, 10°-80°) (P = .02). However, VAS, SSV, and Constant score were all significantly improved at last follow-up (P < .001). AHI decreased significantly (P = .002) from 10 mm (7-14 mm) to 8 mm (0-12 mm). Two percent of the supraspinatus/infraspinatus tendons were Sugaya 1, 24% were Sugaya 2, 35% were Sugaya 3, 12% were Sugaya 4, and 27% were Sugaya 5. Goutallier score progressed for all muscles, but this did not reach significance and mean Goutallier remained <2 for all 4 muscles at last follow-up. Hamada score progressed from 0% >grade 2 preoperatively to 6% >grade 2 at last follow-up. CONCLUSION: Revision rotator cuff repair provides significant pain relief and improvement in functional scores at long-term follow-up. The mild progression of fatty infiltration, AHI, and Hamada score suggests that despite high retear rates (39% of stage 4 and 5 in the Sugaya classification), revision repair could possibly have a protective role on the evolution toward cuff tear arthropathy.

Comparison of bleeding during trochanteric fracture fixation with mini-invasive or conventional side plate fixation: A randomized controlled trial.

BACKGROUND: Trochanteric fractures are a public health issue due to the aging of the population. Treatment aims to reduce their related morbidity and mortality and to allow an early return to independence. Postoperative anemia is associated with poorer functional recovery and an increased mortality rate. The aim of this study was to assess whether minimally invasive side plate fixation (Minimal Invasive Screw System, MISS™) resulted in reduced perioperative bleeding compared with conventional fixation (Pertrochanteric Hip Screw, PHS™). HYPOTHESIS: We hypothesized that minimally invasive side plate fixation (MISS) would result in reduced perioperative bleeding compared with conventional fixation (PHS). PATIENTS AND METHODS: We conducted an open randomized controlled trial with blinded assessment of the primary outcome. Inclusion criteria were patients aged over 65 years with isolated reducible trochanteric fracture. The 2 surgical implants were of the same shape, the only difference between them being the locking mode of the femoral neck screw on the plate of the MISS device, allowing a percutaneous approach. Primary outcome was perioperative bleeding evaluated with Mercuriali's formula. Secondary outcomes included operating time, scar length, length of hospital stay, radiological criteria such as quality of fracture reduction, implant positioning, bone healing, complications and functional recovery compared between the 2 groups. RESULTS: One hundred and eight patients met the inclusion criteria and were randomized to receive either PHS (n=54) or MISS (n=54). Osteosynthesis with MISS significatively reduced perioperative bleeding (median 243mL, interquartile range [152-410] vs. 334mL [247-430] [p=0.0299]), operating time (65min [57-73] vs. 79min [66-89] [p=0.0002]) and scar length after 45 days (7cm [5-8] vs. 14cm [12-15] [p<0.0001]). There was no statistically significant difference between groups in postoperative complications, revision surgery or serious adverse events. CONCLUSION: Compared with PHS, MISS reduced operating time, perioperative bleeding and scar length with no observed functional difference. LEVEL OF EVIDENCE: I.

Arthroscopic advancement of the supraspinatus muscle and tendon for posterosuperior massive rotator cuff tears.

The tension-free repair of retracted supraspinatus tears with the open muscle and tendon advancement technique first described by Debeyre in 1965 gave satisfactory clinical results. The purpose of this anatomical study was to test the feasibility of an arthroscopic supraspinatus advancement technique. A total of 10 cadaveric shoulders were operated. We assessed the feasibility, measured the slide distance, and recorded the position of the suprascapular nerve (SSN) for each shoulder. Reattachment of the tendon to its native footprint was achieved in all cases. The mean slide distance was 38.8 mm ± 3.6 (33-44). The SSN was released and tension-free in all shoulders. Arthroscopic advancement of the supraspinatus muscle and tendon enables complete rotator cuff repair in irreparable retracted posterosuperior tears and is a noteworthy alternative to the other techniques. Level of Evidence: IV.

Partial and complete repairs of massive rotator cuff tears maintain similar long-term improvements in clinical scores.

PURPOSE: The authors have previously published early outcomes of arthroscopic repairs of 86 massive rotator cuff tears (mRCTs) and aimed to determine whether their clinical scores are maintained or deteriorate after 5 more years. METHODS: Of the initial series of 86 shoulders, 2 had deceased, 16 lost to follow-up and 4 reoperated, leaving 64 for assessment. The repairs were complete in 44 and partial in 20, and 17 shoulders had pseudoparalysis. Preoperative assessment included absolute Constant score, shoulder strength, tear pattern, tendon retraction, and fatty infiltration. Patients were evaluated at 8.1 ± 0.6 years (range 7.1-9.3) using absolute and age-/sex-adjusted Constant score, subjective shoulder value (SSV), and simple shoulder test (SST). RESULTS: Absolute Constant score was 80.0 ± 11.7 at first follow-up (at 2-5 years) but diminished to 76.7 ± 10.2 at second follow-up (at 7-10 years) (p < 0.001). Adjusted Constant score was 99.7 ± 15.9 at first follow-up and remained 98.8 ± 15.9 at second follow-up (ns). Comparing other outcomes revealed a decrease in strength over time (p < 0.001) but no change in pain, SSV or SST. Partially-repaired shoulders had lower strength at both follow-ups (p < 0.05). Pseudoparalytic shoulders had lower absolute and adjusted Constant score at second follow-up (p < 0.05), but their net improvements in absolute Constant score were higher (p = 0.014). CONCLUSIONS: Both partial and complete arthroscopic repairs grant satisfactory long-term outcomes for patients with mRCTs, regardless of their tear pattern, fatty infiltration and presence of pseudoparalysis. Absolute Constant score decreased over time for both repair types, but adjusted Constant score remained stable, suggesting that decline is due to aging rather than tissue degeneration. The clinical relevance of this study is that arthroscopic repair should be considered for mRCTs, even if not completely repairable, rather than more invasive and/or risky treatments, such as reverse shoulder arthroplasty.

Publication rate of studies presented at the French Arthroscopic Society Meeting in 2014.

INTRODUCTION: Publication rates for studies reported at French Arthroscopic Society (Société francophone d'arthroscopie, SFA) meetings are not known. A comprehensive search of podium presentations to the 2014 SFA meeting was performed, assessing: (1) publication rate for meeting abstracts, and (2) bibliometric parameters including journal Impact Factor. HYPOTHESIS: The full-text publication rate for abstracts accepted for the 2014 French Arthroscopic Society (SFA) meeting was around 47.1%: i.e., the rate reported for the 2013 meeting of the French Society of Orthopedic Surgery and Traumatology (SoFCOT). MATERIAL AND METHODS: Bibliometric analysis of all abstracts accepted for the 2014 SFA annual meeting was undertaken by the Junior French Arthroscopic Society (SFA Junior), who collated the podium presentations. Reported studies were retrospective in 43 cases (54%) and prospective in 36 (46%). They consisted in clinical studies in 52/79 cases (66%), experimental studies in 4 (5%), cadaver or animal studies in 13 (16.5%), epidemiological studies in 8 (10%), a case report in 1 (1.2%) and a literature review in 1 (1.2%). Thirty-two (40.5%) concerned the shoulder and 31 (39%) the knee. Publication was checked on systematic PubMed-Medline search of authors' names. Articles found on PubMed-Medline were downloaded into the SIGAPS scientific publication search, management and analysis system database. Journal impact factor and SIGAPS category (A to E) were obtained, as were number of citations and h-index. This was a descriptive study, assessing numbers; results were reported as number and percentage. RESULTS: Overall publication rate was 31/79 (39.2%): 20/31 clinical studies (64.5%), 6 cadaver studies (19.4%), 3 epidemiology studies (9.7%), 1 experimental study (3.2%) and 1 literature review (3.2%). Mean 2014 SFA meeting-to-publication time was 18.7 months [range, -2 to 60 months]. Journal SIGAPS categories were A for 4 articles (13.3%), B for 13 (43.3%), C for 3 (10%), D for 9 (30%), with no E category articles but 1 article (3.3%) without SIGAPS category. CONCLUSION: The publication rate for abstracts accepted for report to the 2014 SFA annual meeting was lower than for the 2013 SoFCOT meeting. The high level of the journals in question testified to the quality of the studies reported at the SFA meeting. LEVEL OF EVIDENCE: IV, retrospective study.

Tendon transfers for radial nerve palsy with extensor carpi ulnaris revival: Technique and results.

BACKGROUND: Nerve repair is the gold standard for treatment of radial palsy. In case of failure or contraindication, palliative techniques using tendon transfers provide good results. However, wrist extension frequently shows radial deviation, impairing grip strength. HYPOTHESIS: Associating extensor carpi ulnaris (ECU) revival avoids radial deviation. STUDY DESIGN: Single-center retrospective study. MATERIAL AND METHODS: The inclusion criterion was radial nerve palsy treated by tendon transfers involving revival of the ECU. Nine patients, with a mean age of 33 years [15-60] were included. Four palsies were trauma-induced, 3 tumor-induced and 2 idiopathic. The mean time to treatment was 32 months [4.6-120]. RESULTS: Mean follow-up was 51 months [3-160.7]. Eight patients could be assessed. Wrist extension was balanced in 6 cases, in ulnar deviation in 1 and in radial deviation in the other. Wrist motion was 54° [30°-80°] in extension, 46° [20°-70°] in flexion, with an active motion in the frontal plane of 21° [0°-35°]. Finger extension was possible with the wrist in extension in 6 cases. Thumb abduction was subnormal in 3 cases, incomplete but functional in 4 and barely functional in 1. Fist closure was always complete. Mean QuickDASH score was 41/100 [14-63]. CONCLUSION: This technique is reliable and reproducible, giving good functional results and avoiding the radial deviation of the wrist in extension observed with traditional techniques. LEVEL OF EVIDENCE: IV.

Impact of setting up a bone and joint infection referral center on arthroscopic treatment of septic arthritis of the knee and shoulder: Retrospective study.

INTRODUCTION: Referral Centers for Bone and Joint Infection (BJI) were set up to optimize BJI management thanks to multidisciplinary teamwork. The main aim of the present study was to assess the impact of setting up the Western France Bone and Joint Infection Referral Center on arthroscopic treatment of septic arthritis of the shoulder and knee. The secondary aim was to identify other risk factors for failure of this treatment. The null hypothesis was that there was no difference between the "success group" and the "failure group". MATERIAL AND METHODS: This single-center retrospective study included 52 patients treated for septic arthritis between January 1, 2000 and December 31, 2013 by arthroscopic joint lavage associated to at least 4 weeks' antibiotic therapy. Exclusion criteria comprised: retrospective diagnosis of rheumatoid arthritis after negative bacteriological analysis, early cessation of antibiotic treatment, and follow-up less than 4 weeks. Failure was defined as non-healing after first-line treatment. The primary endpoint was date of treatment compared to the launch date of the Center in the first quarter of 2010. The influence of pre- and intraoperative criteria related to patient, treatment and microorganism was assessed. RESULTS: At follow-up, 17 patients (32.9%) showed failure of first-line treatment and 5 (9.6%) were non-healed at end of treatment, whatever the re-intervention. The failure rate significantly decreased after setting up the Center, from 42.9% to 11.8% (p=0.03). In the failure group, 70.6% of patients showed immunosuppression, versus 37.2% in the success group (p=0.01). Neither time to surgery (p=1), type of microorganism, or performance of antiseptic lavage (p=0.25) or synovectomy (p=0.62) influenced outcome. CONCLUSION: Multidisciplinary management of septic arthritis improved treatment success. LEVEL OF EVIDENCE: III, Retrospective comparative study.
