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: Centred degeneration of the shoulder joint is defined as a degeneration of the glenohumeral surfaces without ascension of the humeral head. We investigated the influence of partial or full thickness rotator cuff tears and/or fatty degeneration of the supraspinatus on the results of total shoulder arthroplasty.

Material and methods: During a multicentric review of 766 cases of centred degeneration of the shoulder joint treated with the Aequalis prosthesis, we identified 555 shoulders in 478 patients with an interpretable preoperative arthroscan. All patients were reviewed with a minimum follow-up of two years (mean 3.6 years). Constant score and radiological findings were recorded. We identified 41 shoulders with partial tears of the supraspinatus and 42 shoulders with full-thickness tears of the supraspinatus alone. Moderate fatty degeneration was observed in 90 shoulders (≤ 2) and severe fatty degeneration of the infraspinatus or the subscapularis (> 2) in 15. We analysed the Constant scores, subjective results, radiological results, and rate of complications in each of these populations.

Results: Rotator cuff tears involving the supraspinatus alone did not have a destabilising effect, the head of the humerus did not influence the postoperative result assessed by the overall Constant score, motion in all planes, subjective result, radiological result, or rate of complications. There was no significant difference in complication rate. Presence or not of cuff repair did not influence these results. Inversely, fatty degeneration ≥ 2 involving the infrastpinatus or the subscapularis had a significant effect, decreasing the Constant score, active external rotation, active anterior elevation, and subjective result. On the contrary, it did not influence the radiological results or the rate of complications.

Discusssion: This multicentric study confirms that the degenerated shoulder joint can remain centred with a solitary tear of the supraspinatus. This has no effect on the clinical result and does not require repair. Inversely, fatty degeneration is highly predictive of the quality of the final result.

Purpose: The best strategy to adopt for the long head of the biceps during total shoulder arthroplasty for centred primary joint degeneration remains a controversial issue. We analysed the influence of long head of the biceps (LHB) tenodesis on outcome.

Material and methods: From retrospective multicentric series of 766 shoulder prostheses implanted for centred primary degeneration of the shoulder joint, we selected 625 shoulders with sufficient data concerning the LHB. We defined two groups: 131 shoulders with LHB tenodesis and 494 shoulders with a preserved LHB. We analysed clinical outcome with the Constant score and subjective outcome at two years. We identified four groups: 70 humeral prostheses without tenodesis, 10 humeral prostheses with tenodesis, 424 total shoulder arthroplastues without tenodesis, and 121 total shoulder arthroplasties with tenodesis.

Results: The Constant score was significantly better in the tenodesis group (74.7) than in the group without tenodesis (70.8). This significant difference was also found for the weighted score and likewise for active anterior elevation and active external rotation in position 1. There was no difference concerning postoperative fatty degeneration. By subgroups, the analysis showed significant improvement in the Constant score for humeral prostheses with tenodesis and total shoulder arthroplasty with tenodesis over the same implants without tenodesis. This same significant difference was observed for the 364 patients who had a minimum follow-up of 36 months: tenodesis improved the Constant score, the weighted Constant score, active anterior elevation, and active external rotation.

Discussion: The causal role of the LHB in shoulder pain is now well documented in the literature. Several authors have advocated tenotomy or tenodesis of the LHB during surgical treatment of rotator cuff tears. The same is not true for shoulder arthroplasty for the treatment of primary degeneration. Dines and Hersch reported their experience with ten patients with a painful total shoulder arthroplasty who were improved with arthroscopic tenotomy or tenodesis.

Conclusion: Our large series confirms that tenodesis of the LHB is preferable during implantation of a humeral prosthesis or a total shoulder prosthesis for the treatment of centred primary joint degeneration with good results that persist over time.

Purpose of the study: The aim of this study was to evaluate the anatomical and technical limits of endoscopic rotator cuff repair. Anatomical results were also compared with functional assessment of the shoulder.

Material and methods: A multicentric serie of 87 patients presenting a full thickness rotator cuff tear repaired endoscopically was retrospectively reviewed at 25.4 months (mean) post surgery. Limits of the surgical technique were studied in correlation with functional results and anatomic radiographic evaluation (arthroscans in 93 p. 100).

Results: Anatomical repair (normal thickness and no contrast in the subacromial space on arthroscan) was achieved in 83 p. 100 of the rotator cuffs with limited damage to the frontal part of the supra spinatus tendon. This percentage fell to 57.8 p. 100 in case of posterior extension of the tear to the supra spinatus tendon and further dropped to 40.8 p. 100 in case of retraction to the apex of the humeral head. Functional outcome evaluated with the Constant score was strongly related to the radiographic cuff condition (p < 0.05). For distal and anterior tears of the supra spinatus tendon, the Constant score at revision was 89.8 points in cases with anatomic repair at revision. This score fell to 75 when the rotator cuff tear was evidenced radiographically (p < 0.0001). For tears involving the entire supra spinatus tendon repaired by arthroscopy, the functional difference at revision was 8 points on the Constant scale. Objective and subjective analysis of the surgical procedure identified significant peroperative elements predictive of clinical and anatomical outcome (difficult reduction, p < 0.05; subjective degree of solidity, p < 0.0001; anatomical aspect of the repaired cuff, p < 0.05).

Discussion: A comparison of our findings with data on equivalent lesions reported in the literature suggests that endoscopic surgery for rotator cuff tears offers both functional and anatomic results equivalent to those achieved with conventional open surgery. This assumes that the surgical procedure is carried out by surgeons experienced in shoulder arthroscopy who can precisely gauge the posterior/anterior extension of the tears and the limits of the surgical technique.
