Anatomic reconstruction is an alternative to transosseous medial patellofemoral ligament reconstruction for recurrent patellar instability that eliminates concern for patellar fracture. The purpose of this study is to describe a modified surgical technique for the treatment of patellar instability and evaluate short-term outcomes. Methods: Modified MQTFL reconstructions were performed between April 2012 and November 2015 for persistent patellar instability for which nonoperative treatment had failed. Included patients had >2+ quadrants of laxity and history of recurrent patellar dislocation. Patients with concurrent injuries, Dejour C or D trochlear dysplasia, or who required a realignment osteotomy were excluded. Anatomic reconstruction of the MQTFL was performed utilizing a sling in the distal medial quadriceps tendon and doubling the graft back to the femoral isometric point. Clinical outcomes were documented via a telephone survey. Physical examination findings were obtained by chart review at 3 to 6 months postoperative. Results: Thirteen modified MQTFL reconstructions were evaluated with a mean follow-up of 29 months. At follow-up, all patients had achieved a full range of motion and 1 to 2 quadrants of passive lateral glide with a good endpoint. There were no recurrent dislocations or complications directly related to the surgery. Overall satisfaction rate was 98%. Median Tegner preinjury and postoperative were 7; 67% returned to sports at the same level. Mean Lysholm and Kujala scores were 97 (SD=4). Conclusion: Modified MQTFL reconstruction is a safe and effective procedure for the treatment of patellar instability. This procedure is a valuable technique for avoiding potential patellar fracture associated with transosseous medial patellofemoral ligament fixation. Level of Evidence: Level IV—case series.
