Closing-wedge distal femoral osteotomy combined with medial patellofemoral ligament reconstruction for recurrent patellar dislocation with genu valgum

Abstract Background Medial patellofemoral ligament reconstruction (MPFLR) is a well-established procedure for addressing recurrent patellar dislocation (RPD) in young patients. However, despite being promising RPD with genu valgum, there scarcity of reports on simultaneous MPFLR and closing-wedge distal femoral osteotomy (CWDFO). The purpose the present study was to observe analyse clinical imaging findings CWDFO combined valgum. Methods From May 2015 April 2018, 25 patients valgum were surgically treated our department. Anteroposterior long-leg, weight-bearing, lower-extremity radiographs, lateral radiographs computed tomography (CT) scans joint obtained, anatomical femorotibial angle (aFTA), mechanical (mLDFA), weight-bearing line rate (WBLR), height, shift (PLS) tibial tubercle–trochlear groove (TT-TG) distance analysed. Validated knee scores, such as Kujala, Lysholm, visual analogue scale (VAS) scores Tegner socres, evaluated preoperatively 2 years postoperatively. Results patients, an average age 19.8 (14–27), evaluated. During 2-year follow-up period, all able achieve better sports level without any problems, no recurrence instability. Compared preoperation, aFTA, mLDFA, WBLR PLS showed statistically significant improvement following (p < 0.001). Meanwhile, differences Insall index TT-TG found. mean Kujala score, Lysholm VAS score socres postoperative improvement. Conclusions suitable treatment can lead short term.
