Arthroscopic Transosseous Repair of Rotator Cuff Tear and Greater Tuberosity Cysts.


ABSTRACT:

Purpose

To evaluate the short-term outcomes of rotator cuff repair in the presence of a greater tuberosity cyst (GTC) using a transosseous repair technique.

Methods

This study included patients who underwent arthroscopic rotator cuff tear repair with a transosseous technique and were evaluated clinically and by postoperative magnetic resonance imaging (MRI) after 1 year. The inclusion criteria were based on the results of preoperative MRI and were as follows: patients identified as having a repairable full-thickness rotator cuff tear associated with the presence of cystic changes at the tendon insertion site of the greater tuberosity, defined as a GTC involving the footprint area of the torn tendon (supraspinatus and/or infraspinatus tendons).

Results

We evaluated 25 patients. The mean preoperative and postoperative American Shoulder and Elbow Surgeons scores were 39.48 (P = .530) and 84.64 (P = .035), respectively; Constant shoulder scores, 38.96 (P < .005) and 80.28 (P = .425), respectively; and University of California-Los Angeles shoulder rating scale scores, 10.6 (P = .045) and 29.04 (P = .315), respectively. The GTC mapping system was easily adopted in all the MRI examinations independently from the quality of the images. The GTCs were mostly located in the superficial anterolateral section of the humeral head and in both the posterolateral sections (superficial and deep).

Conclusions

Arthroscopic transosseous rotator cuff repair led to significant mid-term improvement and satisfactory subjective outcomes with low complication and failure rates in this study. The GTC mapping system could be useful to evaluate GTCs and to aid surgeons in the choice of the best surgical technique.

Level of evidence
