Abstract
Genu valgum is a risk factor for patellar instability. The study purpose was to report on preliminary results of medial patellofemoral ligament (MPFL) reconstruction and simultaneous growth modulation, in patients with patellar instability and genu valgum. A total of seven patients (eight knees) with MPFL reconstruction and medial transphyseal screw insertion for genu valgum correction were assessed using full-length radiographs. Genu valgum corrected from 13.1° to 3.7° at mean 11.7 months, without compromising patellar stability. One patient each had 6° overcorrection and 5° rebound valgus. Guided growth using transphyseal screw during MPFL reconstruction could achieve deformity correction without interference with MPFL graft placement.
