We present a new patch graft procedure using the quadriceps tendon (QT). The surgical procedures are described in detail and our preliminary results reported.
QT patch grafting was performed in 12 patients with an average age at operation of 68.3 years (range 45-82 years). Cuff repairability was evaluated by standard arthroscopic examinations. Subacromial decompression was done as needed. The size of the defect was measured, and the QT was harvested just above the patellar insertion. The QT patch was fixed to the torn edge of the cuff medially, and to the greater tuberosity with suture anchors laterally.
The mean operation time was 175.6 min (range 142-240 min). The mean JOA score was improved from 68.5 points preoperatively to 88.3 points postoperatively. Postoperative MRI showed 4 typeI cases, 7 typeII cases, and 1 typeV case according to Sugaya's classification.
A QT graft is thicker than the fascia lata, which is commonly used as patch material, and is expected to work as a depressor of the humeral head.
