Patients with posttraumatic ankle osteoarthritis (OA) typically present with asymmetric involvement of the tibiotalar joint, resulting in valgus or varus deformity of the ankle and hindfoot. Without appropriate treatment, patients with asymmetric ankle OA typically develop full end-stage ankle OA. Ankles with valgus deformities suffer from a lateral joint overload with subsequent lateral tibiotalar joint degeneration, which causes further lateral load shift. In these cases patients may benefit from joint-preserving realignment surgery to unload the degenerated lateral area and normalize joint biomechanics. This article describes the authors' algorithm for the treatment of patients with asymmetric valgus ankle OA.

An alternative fixation for all mild and moderate hallux valgus cases enabling intraoperative readjustment.
J Orthop Surg Res
January 2025
Department of Orthopaedics and Traumatology, Adana City Training and Research Hospital, University of Health Sciences, Adana, Turkey.
Background: The development of a cost-effective and easily applicable fixation method to address all components of hallux valgus (HV) surgery is of great importance to the field. This study aims to assess the clinical efficacy of an alternative fixation method that combines the advantages aspects of commonly used distal osteotomy techniques and evaluate its level of applicability in the treatment of mild and moderate HV cases.
Methods: The retrospectively designed study was conducted at Adana City Training and Research Hospital, Adana, Türkiye.

The past several decades have seen significant advancements in joint replacement surgery for rheumatoid arthritis (RA). Joint replacement procedures have become vital options for patients with severe joint damage and functional impairment. There has been an increased emphasis on personalized surgical strategies that tailor joint replacement decisions based on a patient's unique clinical characteristics and the extent of joint damage.

Foot Ankle Int
January 2025
Department of Orthopedics and Rehabilitation, Carver College of Medicine, University of Iowa, Iowa City, IA, USA.
Background: To provide improved treatment for hallux valgus (HV), we sought to understand more about the pathophysiologic connection between flatfoot deformity and HV by comparing coronal plane alignment of the medial column of the foot for patients with isolated HV, isolated flatfoot, and combined HV-flatfoot vs controls.
Methods: This study retrospectively assessed a consecutive series of 33 patients with combined symptomatic and radiographic HV and flatfoot, 33 isolated symptomatic HV, 33 isolated symptomatic flatfoot, and 33 controls. The medial column alignment was assessed in the coronal plane using 3-dimensional weightbearing computed tomography (WBCT); rotation was measured for the navicular, medial cuneiform, and first metatarsal (M1).
Effects of functional strength training on pain, function, and lower extremity biomechanics in patients with patellofemoral pain syndrome: a randomized clinical trial.
J Orthop Surg Res
January 2025
Institute of Sport, Exercise & Health, Tianjin University of Sport, Tianjin, China.
Background: Patellofemoral pain syndrome (PFPS) is a common disorder affecting the lower extremity. This study aimed to compare the effects of functional strength training (FST) and standard strength training (SST) in PFPS patients.
Methods: Forty college students (aged 18-30 years) with PFPS and no exercise habits were randomized into FST group (n = 20) and SST group (n = 20).
