In this study, the effects of medial collateral ligament (MCL) release and the limb correction strategies with pre-existing MCL laxity on tibiofemoral contact force distribution after high tibial osteotomy (HTO) were investigated. The medial and lateral contact forces of the knee were quantified during simulated standing using computational modeling techniques. MCL slackness had a primary influence on contact force distribution of the knee, while there was little effect of simulated limb correction. Anterior and middle bundle release, which involved the partial release of two-thirds of the superficial MCL, was shown to be an optimal surgical method in HTO, achieving balanced contact distribution in simulated weight-bearing standing.

Introduction: Clinical data on osseointegration (OI) for limb replacement indicates a concerning increase in mechanical complications after five years post-implantation. Since adequate bone-implant contact and proper implant alignment are critical factors for successful osseointegration, it is essential to identify the factors influencing these outcomes. This study aimed to assess the effects of residual femur length and implant sizing on bone-implant contact and implant alignment.

Background: Timely recognition and addressing of concomitant cartilage damage at the time of meniscal allograft transplantation (MAT) is critical to warrant future success. However, there remains a scarcity of data comparing outcomes between MAT with and without cartilage procedures.
Purpose: To compare patient-reported outcomes and rates of complications, failures, reoperations, and graft survivorship after MAT with concomitant cartilage procedures (MAT/Cart) and MAT without (MAT/NoCart).

In trampolining, optimizing body orientation during landing reduces injury risk and enhances performance. As trampolinists are subject to motor variability, anticipatory inflight corrections are necessary to regulate their body orientation before landing. We investigated the evolution of a) body orientation and b) limb position (i.
