Objective: We retrospectively investigated the preoperative and postoperative sports and physical activities (SPA) of elderly patients with medial compartment knee osteoarthritis who underwent opening-wedge high tibial osteotomy (OWHTO).
Methods: Fifty-six patients (62 knees) with medial compartment knee osteoarthritis were included in the study. The patients comprised 45 women and 11 men with a mean age at surgery of 71.6 years (range, 65-81 years). The mean follow-up period was 51±7 months. Patients who performed SPA to maintain their health for at least 30 min per session more than once a week were defined as SPA cases. The preoperative and postoperative ratios of SPA cases, the time to resuming or starting postoperative SPA, and the frequency of performing postoperative SPA were investigated. Clinical results were assessed using the Lysholm score.
Results: Fifteen patients (26.7%) performed SPA before OWHTO and 14 (25.0%) performed SPA after OWHTO (P=0.21). The mean time to resuming or starting SPA after surgery was 14.1±10.0 months, and the frequency of postoperative SPA sessions was 4.2±2.1 per week. The mean Lysholm score significantly improved from 60.8±8.9 preoperatively to 92.5±2.5 postoperatively (P<0.0001).
Conclusion: The ratio of patients who performed SPA after OWHTO was still <30% , and it took a comparatively long time for patients to resume or start SPA after surgery.

Editorial Commentary: The Free Floating Disc Shaped Polycarbonate-Urethane Meniscal Implant Has High Reoperation Rates at 24 Months Follow-up.

A free-floating disc shaped polycarbonate-urethane ultra-high molecular weight polyethylene fiber reinforced medial compartment implant is designed for symptomatic postmedial meniscectomy syndrome. Because it is not sutured into place, an intact 2mm meniscus rim with intact anterior and posterior meniscal horns are required. In a recent 24-month follow-up study, only 64% of the original implants were retained.

Proximal tibiofibular joint detachment (PTFJD) is a fibular untethering procedure during lateral closing-wedge high tibial osteotomy (LCWHTO) for varus knee osteoarthritis. However, the PTFJD procedure is technically demanding, and confirmation of clear joint separation is not straightforward. The aim of this study was to compare the degree of completion and safety of PTFJD versus tibial-sided osteotomy (TSO); this latter procedure is our novel technique for fibular untethering during LCWHTO.

: Despite its advantages, lateral close-wedge high tibial osteotomy (LCWHTO) requires proximal tibiofibular joint detachment (PTFJD) or fibular shaft osteotomy for gap closing. These fibula untethering procedures are technically demanding and not free from the risk of neurovascular injuries. Our novel fibula untethering technique, tibial-sided osteotomy (TSO) near the proximal tibiofibular joint (PTFJ), aims to reduce technical demands and the risk of injury to the peroneal nerve and popliteal neurovascular structures.

Popliteal cysts (PCs) are occasionally accompanied by knee osteoarthritis (OA) and varus malalignment. However, whether concomitant arthroscopic excision of PCs with medial open-wedge high tibial osteotomy (MOWHTO) improves the osteoarthritic environment remains unclear. Therefore, this study assessed serial changes in C-size, medial meniscus extrusion (MME), and cartilage status for up to 2 years following an MOWHTO.

This retrospective study aimed to evaluate the difference in the temporomandibular joint (TMJ) space volume between the deviated (Dev) and non-deviated (NDev) side following transoral vertical ramus osteotomy (TOVRO) in patients with mandibular prognathism combined with asymmetry using reconstructed 3-dimensional images. Sixty joints from 30 patients who underwent TOVRO between January 2018 and December 2021 were included. Computed tomography (CT) or cone-beam CT was performed before surgery (T0), and 6 (T1) and 12 months postoperatively (T2).
