Study finds high rate of return to sport after MPFL reconstruction
Patients undergoing medial patellofemoral ligament reconstruction for patellar instability can expect a high rate of return to sport with or without concomitant osteotomy, according to published results.
Brooks N. Platt, MD, and colleagues performed a systematic review of 23 articles that included 930 patients - 786 of which were athletes - who underwent medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar dislocation.
“A random-effects model was used to evaluate return to sport rates, subsequent level, and rate of instability recurrence,” the researchers wrote in the study. “Meta-regression was used to compare return to sport rates in patients undergoing MPFL reconstruction without osteotomy compared with those treated with simultaneous tibial tubercle osteotomy or trochleoplasty,” they added.
Overall, patients returned to sport at a mean of 6.7 months after surgery with an 8.8% complication rate, according to the study. Preoperative to postoperative Kujala scores were 60.3 and 90, respectively.
Platt and colleagues found a return to sport rate of 92.8% and noted patients returned to or surpassed their preoperative level of activity in 71.3% of all cases. Additionally, researchers noted no differences between patients who received an additional osteotomy (10.5% of patients) vs. those who did not.
“Overall, these findings support MPFL reconstruction as an effective surgical treatment for athletes with recurrent patellar dislocation,” they wrote. “Surgeons can counsel their patients that they can expect a high rate of return to sport after MPFL reconstruction surgery alone or with concomitant osteotomy.”
