Abstract

Background: Partial-thickness rotator cuff tears (PTRCTs) are one of the leading causes of shoulder dysfunction. Successful results have been reported with different treatment techniques, but the long-term consequences of these procedures are not yet clearly known. The purposes of this study were to evaluate and compare the mid- and long-term clinical outcomes of arthroscopically repaired bursal-side PTRCTs after conversion to full-thickness tears and identify the possible effects of age, gender, and hand dominance on clinical outcomes.

Methods: Twenty-nine patients who had undergone arthroscopic repair of a significant bursal-side PTRCT were functionally evaluated. The repair was made after conversion to a full-thickness tear. The average patient age was 55.2 years (range 35-69 years, SD ±7.6 years). Clinical outcomes were evaluated at 2 and 5 years after surgery. Constant Shoulder Score (CSS) and Visual Analogue Scale for Pain (VAS pain) were used as outcome measures.

Results: The average CSS improved from 38.9 preoperatively to 89.2 and 87.8 at 2 and 5 years after surgery, respectively (p < 0.001). The average VAS pain score decreased from 7.90 preoperatively to 1.17 and 1.31 at 2 and 5 years after surgery, respectively (p < 0.001). A significant improvement was detected in patient functional outcomes and VAS pain scores at 2 and 5 years after surgery compared with the preoperative period. The patients who underwent surgery from their non-dominant extremity showed a significantly higher CSS increase relative to those who underwent surgery on the dominant extremity (p = 0.022).

Conclusions: Arthroscopic repair of high-grade bursal-side PTRCTs after conversion to full-thickness tears is a reliable surgical technique with good functional outcomes and pain relief both at mid- and long-term follow-ups. Surgery on the non-dominant side may be related to better functional outcomes.
