Abstract
Purpose
To elucidate the clinical outcomes of medial retinaculum plasty versus MPFL reconstruction with concomitant tibial tubercle transfer.
Methods
From January 2014 to July 2018, 57 patients who underwent tibial tubercle transfer combined with medial retinaculum plasty or MPFL reconstruction were enrolled in the present study. The 57 patients were divided into two comparison groups according to the therapeutic protocol. The 25 patients in group I underwent the medial retinaculum plasty and tibial tubercle transfer. The 32 patients in group II underwent the MPFL reconstruction and tibial tubercle transfer. Clinical outcomes were assessed using the knee injury and osteoarthritis outcome score, Kujala score, congruence angle, patellar tilt angle, patellar lateral shift, tibial tuberosity–trochlear groove distance and Caton–Deschamps Index. The clinical outcomes were compared between the two groups preoperatively and at the time of the last follow-up.
Results
Significant improvement was seen in both groups postoperatively (P < 0.05). There were no significant differences in the knee injury and osteoarthritis outcome score, Kujala score, congruence angle, patellar tilt angle, patellar lateral shift, tibial tuberosity–trochlear groove distance and Caton–Deschamps Index between the two groups (P > 0.05).
Conclusion
The combined medial retinaculum plasty and tibial tubercle transfer achieved similar clinical outcomes versus the MPFL reconstruction with concomitant TTT. This therapeutic protocol was a good option in treatment of patellar dislocation with increased TT–TG distance or patella alta.
