The article discusses the issue and our own experience of local therapy for osteoarthritis of the ankle joint with injections of linear hyaluronic acid under ultrasound navigation. Since the ankle joint is difficult in terms of surgical treatment in general and endoprosthetics in particular, a course of intra-articular injection of 1% Flexotron Forte hyaluronate, especially in the early stages of dystrophic changes in cartilage, is a promising method for relieving pain, chondroprotection and preserving the biomechanics of the joint, and ultrasound navigation when performing manipulation, it ensures the most accurate introduction of the drug into the joint cavity.

Ankle arthritis is a severely disabling condition. Treatment poses many unique challenges to orthopaedic surgeons because ankle kinematics differs from that seen in the hip or knee joint and the loads transmitted through the ankle are greater during activity. Historically, motion-sacrificing procedures dominated management of ankle arthritis.

These lesions are difficult to treat because of the poor blood supply and poor regenerative capacity of the talar articular cartilage. It is important to provide a comprehensive overview of the clinical presentation, diagnostic tools, and nonsurgical and surgical treatment strategies for osteochondral lesions of the talus.

Background: Patients with transfemoral amputation experience socket-related problems and musculoskeletal overuse injuries, both of which are exacerbated by asymmetric joint loading and alignment. Bone-anchored limbs are a promising alternative to treat chronic socket-related problems by directly attaching the prosthesis to the residual limb through an osseointegrated implant; however, it remains unknown how changes in alignment facilitated through a bone-anchored limb relate to loading asymmetry.
Questions/purposes: What is the association between femur-pelvis alignment and hip loading asymmetry during walking before and 12 months after transfemoral bone-anchored limb implantation?
Methods: Between 2019 and 2022, we performed 66 bone-anchored limb implantation surgeries on 63 individuals with chronic socket-related problems.

Introduction: Accurate joint moment analysis is essential in biomechanics, and the integration of direct collocation with markerless motion capture offers a promising approach for its estimation. However, markerless motion capture can introduce varying degrees of error in tracking trajectories. This study aims to evaluate the effectiveness of the direct collocation method in estimating kinetics when joint trajectory data are impacted by noise.

Runners often reduce their pace during inclined running to maintain a constant metabolic workload, known as iso-efficiency speed (a speed-incline combination with the same metabolic intensity as level running). This study investigates changes in lower extremity (LE) joint work profiles when running on an incline at iso-efficiency speed. Eleven collegiate distance runners completed a treadmill running task under three conditions (0%, 4%, and 8% incline).
