Double-Row Root Repair with Bridging Centralization Using Double Nonsliding Anchors for Medial Meniscus Posterior Root Tear.

Medial meniscal posterior root tears disrupt the "hoop" function of the meniscus and may lead to knee osteoarthritis. Although root repair could be a key to osteoarthritis prevention, this surgery does not necessarily guarantee an optimal result even when combined with meniscal centralization and high tibial osteotomy. To address this issue, we made five modifications to the original combined approach, namely two anchors to fix the root, instead of one; bridging centralization instead of single centralization; release of the meniscotibial capsule vs no release; release of valgus stress before knot tying vs no release; and prohibiting postoperative cross-legged sitting and sitting on heels.

Derotational Hybrid Closed-Wedge High Tibial Osteotomy for Knee Osteoarthritis With Patellar Subluxation Caused by Tibial Torsional Deformity.

Patellar subluxation and recurrent dislocation are commonly treated with medial patellofemoral ligament reconstruction, and patients with predisposing factors for these problems often require additional bony realignment procedures. However, these procedures mainly address problems in the axial plane, and patients with medial-compartmental knee osteoarthritis may require further realignment in the coronal plane. In this Technical Note article, we introduce our technique for derotational hybrid closed-wedge high tibial osteotomy.

Femoral-varus tibial-valgus osteotomy (FVTVO) for neutrally-aligned knee osteoarthritis with severe joint line obliquity enables return to sports activities: A case series study.

Background: Re-alignment surgeries for uni-compartmental knee osteoarthritis, such as high tibial osteotomy (HTO) for varus knees or distal femoral osteotomy (DFO) for valgus knees, are recognized as standard strategies. However, the treatment strategy has not been established for patients with a neutrally-aligned osteoarthritic knee with severe joint line obliquity (JLO) owing to the combination of a valgus femur and a varus tibia; i.e.
