Background: Surgical treatment of knee osteoarthritis (KOA) complicated by extra-articular deformity has always been controversial regardless of whether it is simultaneous or staged. Simultaneous total knee arthroplasty (TKA) combined with supracondylar osteotomy without plate for treatment of KOA complicated by femoral varus deformity has not been reported in the literature.
Case Summary: A 53-year-old Chinese woman complained of left knee pain for 6 years that worsened for 4 mo during her visit on April 3, 2020, accompanied by instability in walking, which seriously affected quality of life. According to her medical history and preoperative imaging, the patient was diagnosed with left KOA with varus deformity. We used the angular center of rotation principle for osteotomy of the femur deformity and placed a poststabilized femur prosthesis into the knee joint. At the same time, a 13 mm × 130 mm femur extension rod was used instead of a steel plate to fix the end of the femur osteotomy, reducing the possible complications caused by steel plate implantation and reducing the economic burden on patients. The operation successfully solved two major problems of KOA and varus deformity, and the clinical and imaging evaluation of postoperative follow-up were satisfactory.
Conclusion: TKA and supracondylar femoral osteotomy can be used for simultaneous KOA treatment and deformity correction.

Serial Quantitative Evaluation of Load Redistribution and Osteotomy Gap After Medial Open-Wedge High Tibial Osteotomy.

The goal of medial open-wedge high tibial osteotomy (MOW-HTO) is to redistribute load by realigning the lower limb. This surgery is indicated for mild to moderate medial compartment osteoarthritis with varus deformity in cases unresponsive to conservative treatment. Procedures for accompanying cartilage lesions, such as multiple drilling on the medial femoral condyle (MFC), are often performed simultaneously, potentially affecting bone metabolism along with load redistribution and union progression.

Introduction: Evaluating the mechanical-anatomical alignment and angles of the knee joint is crucial for athletes. We aimed to analyse the relationship between lower extremity bone alignment and the importance of the Q angle (QA) in male athletes.
Methods: We included 38 male professional football athletes without any alignment or varus-valgus deformity who actively played football in various football clubs in Istanbul.
Distal Humerus Physeal Separation: Diagnostic Challenges and Implications.

Distal humerus physeal separation is an uncommon and often misdiagnosed injury in infants and young children, frequently resulting in delayed treatment. We report three cases of distal humerus physeal separation that presented with different clinical scenarios with different management approaches. The first case describes a nine-month-old girl who was initially treated for presumed elbow cellulitis before presentation to our centre six weeks later.

Purpose: Tibial valgus osteotomy has shown to be a successful and cost-effective procedure. The advent of image processing and three-dimensional (3D) printing is an interesting tool for achieving more accurate and reproducible results. The aim of our study was to compare the accuracy of the conventional technique and the use of customized guides in the correction of tibial deformities in tibial varus patients, the surgical and clinical benefits, and the impact of treatment in the outpatient setting.

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.
