Abstract:
Medial patellofemoral ligament (MPFL) reconstruction is an important surgical therapy for recurrent patellar dislocation. However, few studies have focused on exercise therapy after MPFL reconstruction. Therefore, the first purpose was to compare the active and traditional postoperative exercise therapies on the recovery of knee joint function and reduction of muscle atrophy after MPFL reconstruction, and the second purpose was to compare the active and traditional postoperative exercise therapies on the patellar stability after MPFL reconstruction. Methods The cases of 31 patients with recurrent patellar dislocation treated with patella double semi-tunnel anatomical MPFL reconstruction from February 2016 and February 2019 were retrospectively reviewed. The clinical outcomes, including the patellar tilt angle (PTA), lateral patellofemoral angle (LPFA), thigh circumference reduction, Kujala score, and Lysholm score, were compared between two groups (i.e., active exercise and traditional exercise groups) preoperatively, 3 months postoperatively, 6 months postoperatively, 12 months postoperatively, and 24 months postoperatively. Results The Kujala score was significantly higher in the active exercise group than traditional exercise group 3 months postoperatively (80.06 vs. 74.80, P & lt; 0.01), 6 months postoperatively (89.19 vs. 82.07, P & lt; 0.01), 12 months postoperatively (91.43 vs. 86.60, P & lt; 0.01), and 24 months postoperatively (92.50 vs. 90.27, P = 0.02). Similarly, there was a higher Lysholm score in the active exercise group compared with traditional exercise group 3 months postoperatively (81.25 vs. 76.53, P & lt; 0.01), 6 months postoperatively (89.81 vs. 84.80, P & lt; 0.01), 12 months postoperatively (93.25 vs. 88.40, P & lt; 0.01), and 24 months postoperatively (93.69 vs. 90.67, P & lt; 0.01). Significantly lower thigh circumference reduction was reported in the active exercise group compared with that in the traditional exercise group 3 months postoperatively (1.90 ± 0.57 vs. 2.45 ± 0.45, P & lt; 0.01) and 6 months postoperatively (1.50 ± 0.31 vs. 1.83 ± 0.32, P & lt; 0.01). No statistical difference was observed between the two groups in terms of PTA ( P & gt; 0.05) or LPFA postoperatively ( P & gt; 0.05). Conclusions Our results suggested that active exercise therapy might benefit the early recovery of knee joint function and reduction of muscle atrophy in patients with recurrent patellar dislocation after MPFL reconstruction.
