Introduction:
The footprint medialization allows a tension free repair in severely retracted rotator cuff tears (RCT), thereby de-creasing the rate of retear. The purpose of the study was to evaluate the clinical and radiological results in a cohort of chronic RCT treated with medialized repair. Secondary purpose was to analyze the impact of medialization length on shoulder function and tendon healing.
Hypothesis:
It was hypothesized that the medialization length would have an impact on clinical and radiological outcome.
Material And Methods:
A consecutive series of thirty patients that underwent arthroscopic repair of a massive posterosuperior RCT at a single institution were retrospectively studied at mean follow-up 18.4months (SD 15.3; range 9-58). The medialization of the medial footprint was measured intraoperatively. Preoperative and postoperative examination included active range of motion, abduction strength, pain assessment, and functional scores. The postoperative rotator cuff integrity was evaluated according to the Sugaya's classification. Types IV-V were categorized as absence of healing.
Results:
At final follow-up the clinical outcomes were significantly improved in all patients (p≤0.001) with the exception of external rotation that displayed no significant improvement (p=0.05). In group 1 (n=8) medialization length was≤10mm (mean 8, SD 1.9) and in group 2 (n=14)>10mm (mean 12.6, SD 1.7). There were no significant differences regarding preoperative and postoperative clinical outcomes (p>0.05) between two groups. Group 2 demonstrated moderate correlation between length of medialization and Sugaya stage of tendon healing (r=0.53, p=0.049). Absence of healing was noted in 4/22 patients, 1/8 in group 1 and 3/14 in group 2.
Discussion:
Medialized repair is an effective technique for treating chronic, massive and retracted posterosuperior RCT. A medialization of the footprint less than or equal to 10mm is recommended, as it was associated with good clinical and radiological results. The rate of tendon healing decreases when medialization exceeds 10mm.
Level Of Evidence:
III.
