Concurrent arthroscopic meniscal repair during open-wedge high tibial osteotomy is not clinically beneficial for medial meniscus posterior root tears

Purpose This prospective study aimed to investigate the clinical benefits of meniscal repair during open-wedge high tibial osteotomies (OWHTOs) in patients with medial meniscus posterior root tears (MMPRTs) and to identify potential risk factors for meniscal healing. Methods Ninety patients with deg...

Description
Summary:Purpose This prospective study aimed to investigate the clinical benefits of meniscal repair during open-wedge high tibial osteotomies (OWHTOs) in patients with medial meniscus posterior root tears (MMPRTs) and to identify potential risk factors for meniscal healing. Methods Ninety patients with degenerative MMPRTs were included in the final cohort and randomized into three groups. The patients in Group A ( n  = 30) underwent OWHTO and arthroscopic all-inside meniscal repair concurrently, those in Group B ( n  = 34) underwent OWHTO only, and those in Group C ( n  = 26) underwent arthroscopic partial meniscectomy. Clinical and radiological outcomes were recorded, and meniscal healing was evaluated during second-look arthroscopy. Logistic regression analysis was performed to identify risk factors for meniscal healing. Results After a minimum follow-up of 24 months, no significant differences between Groups A and B regarding the final Lysholm ( p  = 0.689) or Hospital for Special Surgery (HSS) scores ( p  = 0.256) were observed. There were significant differences among the three groups regarding the hip–knee–ankle angle (HKA), weight-bearing line (WBL) ratio, medial proximal tibial angle (MPTA), and joint line convergence angle (JLCA) ( p
