Purpose of the study: Surgical treatment of rotator cuff tears (RCT) in the older subject is genearlly considered to best involve simple debridement without any attempt at repair. This is however no evidence concerning the healing capacity of tendon repairs after RCT in the older subject. The purpose of this study was to assess the functional outcome of arthroscopically repaired RCT in subjects aged over 65 and to determine the healing pattern.

Materials and Methods: This was a non-randomized prospective study which included patients aged over 65 years who presented a full thickness RCT repaired arthroscopically. The patients were evaluated preoperatively and at last follow-up with the simple shoulder test (SST) and the Constant score. A control arthroscan was obtained systematically six months postoperatively.

Results: From January 2001 through December 2004, 88 patients, mean age 70 years were included in this study with a mean follow-up of three years (range 2–5 years). The tear involved two tendons in 45 shoulders, the frontal retraction was distal in 58 shoulders, the index of fatty degeneration was 0.6 (range 0–3) preoperatively and 13 patients presented stage 1 chondral lesions. The SST improved from 2.4 (range 1–6) preoperatively to 9.7 (3–12) at last follow-up (p< 0.001) and the Constant score from 45 (10–70) to 77.7 (49–93) (p< 0.001) Seventy-seven patients (87.5%) had a control arthroscan and 45 had an intact cuff. For the patients with an intact cuff, the SST was 10.6 and the Constant score 81.6 versus respectively 7.8 and 72.1 for patients with a non intact cuff (p< 0.001). Factors predictive of non healing were size of the tear (p=0.02), its frontal extension (p=0.01), its tendinous aspect (p=0.02) and difficult reduction (p=0.005). There was no increase in the size of the tears (p=0.46). Six patients presented Hamada stage 1 osteoarthritis at last follow-up.

Discussion: This study is the first to demonstrate objective evidence of tendon healing after arthroscopic repair of RCT in patients aged over 65 years. In 59% of the patients, the arthroscan demonstrated intact cuffs with a significant improvement in the functional results.

Conclusion: Arthroscopic repair of RCT in subjects aged over 65 years provides satisfactory results and can be proposed as treatment.

Purpose of the study: Completely arthroscopic repair of rotator cuff tears is widely considered as the standard treatment. We reviewed a multicentric retrospective series of patients.

Material and methods: This series of arthroscopic repairs of full-thickness tears of the supraspinatus and infraspinatus were assess with the Constant score together with arthroMRI or arthroscan at one year follow-up at least. Data were analyzed with SPSS10. The series included 576 patients who underwent surgery from January 2001 to June 2003. Mean age was 57.7 years, 52% males and 60% manual laborers. Mean preoperative Constant score was 46.4/100 (r13.4). The tear was limited to the supraspinatus in 69% of patients with extension to the upper third of the infraspinagus for 23.5% and to all tendons for 7.5%. The supraspinatus tear was distal in 41.7% of patients, intermediary for 44%, and retracted for 14.3%. Arthroscopic repair was performed in all cases, with locoregional anesthesia for 60.9%. Implants were resorbable for 33% and metallic for 62.1%. Acromioplasty was performed for 92.7% and capsulotomy for 14.9%.

Results: The mean subjective outcome was scored 8.89/10. The Constant score improved from 46.3±13.4 to 82.7±10.3 with 62% of patients being strictly pain free. The force score improved from 8.5±3.7 to 13.6±5.4. Outcome was excellent or very good for 94% of the shoulders at 18.5 mean follow-up. The rate of complications was 6.2% with 3.1% of patients presenting prolonged joint stiffness, 2.7% reflex dystrophy, 0.2% infection and 0.2% implant migration. The cuff was considered normal in 55.7% of the shoulders with an intratendon addition image for 19%, i.e. 74.7% non-torn cuffs. A point leakage was noted in 9.5% with pronounced leakage in 15.7%, i.e. 25.2% recurrent tears.

Discussion and conclusion: The functional outcome obtained after arthroscopic repair of rotator cuff tears is good. Arthroscopy has the advantage of a low rate of complications yet provides good clinical and anatomic results. Age is correlated with functional outcome and healing, but should not be considered as a contraindication.

Purpose of the study: A statistical analysis of correlations between clinical outcome and anatomic results after arthroscopic repair of rotator cuff tears.

Material and methods: This multicentric series of rotator cuff tears was limited to the supraspinatus and infraspinatus. The statistical analysis searched for correlations between the clinical outcome (Constant score) and anatomic results (arthroscan and arthroMRI). The series included 576 patients, mean age 57.7 years, 52%μ males and 60% manual laborers. The tear was limited to the suprapsinatus in 69% of patients, with extension to the upper third of the infraspinatus in 23.5% and all tendons in 7.5%. The supraspinatus tear was distal in 41.7% of patients, intermediary in 44% and retracted in 14.3%. Fatty degeneration of the supraspinatus was noted grade 0 in 59.7%, 1 in 27.1%, 2 in 10.8% and 3 in 2.4%.

Results: The Constant score (46.3 preoperatively and 82.7 postoperatively) was strongly correlated with successful repair. The correlation was found for force, motion, and activity, but not for pain. The clinical outcome was correlated with extension, retraction, cleavage, and degeneration of the preoperative injury. The anatomic result was statistically less favorable for older, more extended, retracted, and cleaved tears or tears associated with fatty degeneration. Age was correlated with the extent of the initial tear and also with less favorable clinical and anatomic results. Work accidents were correlated with less favorable clinical outcome.

Discussion: The large number of anatomic controls with contrast injection facilitated demonstration of several statistically significant correlations. This enabled disclosure in a single series of evidence confirming earlier reports in the literature: repair of cuff tears improves the overall functional outcome for massive tears; the anatomic result depends on the size of the initial tear; pre-operative fatty degeneration is an important prognostic criteria; cuff healing is age-dependent.

Conclusion: Study of anatamoclinical correlations helps guide therapeutic decision making and enables the establishment of reliable prognostic criteria after arthroscopic repair of rotator cuff tears.

Purpose of the study: Arthroscopic repair of rotator cuff tendons is a well-described technique. Clinical outcome is good. The purpose of this work was to assess tendon healing as observed with the arthroscan after arthroscopic repair of rotator cuff tears. We search for epidemiological, anatomic, and technical factors predictive of healing.

Material and methods: This was a prospective consecutive non-randomized series of 167 shoulders. All patients were assessed preoperatively with the Constant clinical score and had a standard imaging protocol for assessing the status of the rotator cuff. Arthroscopic repair was used in all cases. Outcome was assessed with the Constant score and an arthroscan was available for 148 patients.

Results: Mean patient age was 59 years, 49% male and 77% dominant side. Mean duration of symptoms before repair was nine months. The tear resulted from trauma in 28% and was a work accident in 9%. The preoperative functional assessment was 52.48. An isolated supraspinatus tear was observed in 68% of the shoulders. Frontal retraction of the supraspinatus was distal in 74%. For 29 shoulders, reduction was difficult and the quality of the tendon was considered normal in 56. Non-anatomic repair was required in six cases. The Constant score at last follow-up (19 months) was 80. An arthroscan was available for 148 shoulders: healing was anatomic in 69, defective healing was observed in 27 and repeated tears were noted in 52. Factors predictive of healing were: demographic (lesion duration less than six months, non-dominant side, young patient, female gender, sedentary lifestyle); anatomic (isolated lesion of the supraspinatus with little extension and no retraction); technical (normal easily reduced tendon, good quality bone).

Discussion: The time before surgical management of rotator cuff tears was an important factor in this study. Tendon and muscle alterations after rotator cuff tears could explain, at least in part, healing failures.

Conclusion: This study confirmed the good functional and anatomic results obtained with arthroscopic repair of rotator cuff tears.

Purpose: The purpose of this study was to compare meniscal lesions observed arthroscopically with magnetic resonance imaging (MRI) descriptions.

Material and methods: MRI were read by one operator blinded to the arthroscopic findings. The operator noted the presence or absence of lesions, the topography of the lesion, and the Trillat classification. 188 menisci were studied in 94 patients.

Results: Arthroscopically there were 90 healthy menisci and MRI described 89 healthy menisci, giving an arthroscopic specificity of 98.9%. There were 98 meniscal lesions arthroscopically and 95 at MRI, giving 96.6% sensitivity. The medial meniscus was damaged in 78 cases and the lateral meniscus in 20. Arthroscopy and MRI found the same type of lesion in 62 of 98 cases, identified on the medial meniscus in 47 out of 78 and the lateral meniscus for 15 out of 20. MRI recognised 25/29 horizontal lesions but only one radial lesion of the medial meniscus among the seven cases identified arthroscopically. The topography was concordant in 18/98 cases. MRI oversized the lesion in 54/98 cases.

Discussion: MRI remains the gold standard complementary examination for the diagnosis of meniscal lesions, with high sensitivity and specificity. The precise anatomic description of the lesion provided by the MRI corresponds less well with the arthroscopic findings. Certain lesions appear to be easier to identify, particularly horizontal lesions, while others, particularly radial lesions, are more difficult to demonstrate.
