Osteochondritis dissecans (OCD) is a condition in which a portion of articular cartilage separates from the bone together with the underlying subchondral bone. Its classical localization is the medial femoral condyle. We presented a 14-year-old boy who had OCD lesions in both the medial femoral condyle and patella in the same knee joint. He presented with complaints of pain, swelling, and locking following sports activities. Magnetic resonance imaging showed completely detached loose bodies causing instability. Arthroscopic treatment was performed including in situ fixation of the condylar lesion and debridement of patellar lesions. At six-month follow-up, he had full range of motion of the knee joint, with some pain in the patellar grind test.

Background: Functional recovery and return to sports after fixation of osteochondritis dissecans (OCD) lesions of the knee with osteochondral autologous transplantation (OAT) have not been well investigated.
Purpose: To retrospectively evaluate the functional recovery and clinical outcomes after internal fixation with OAT for knee OCD.
Study Design: Case series; Level of evidence, 4.

Purpose: Malalignment of the lower extremity can affect one, two or all three anatomic planes. We hypothesized an influence between the malalignment of the coronal and axial planes.
Methods: A total of 356 lower extremities of 226 patients were included.

Purpose: The medial collateral ligament (MCL), and posterior oblique ligament (POL) are the primary valgus stabilisers of the knee, and clinical examinations in grading valgus instability can be inherently subjective. Stress radiography of medial-sided knee injuries provides objective diagnosis and was analysed in this study. We hypothesised that (1) medial joint space opening would increase cutting the superficial MCL (sMCL), POL and anterior cruciate ligament (ACL); (2) isolated deep MCL (dMCL) injury would not increase medial joint space opening; (3) medial joint space opening would increase at higher flexion angles.

Introduction Implant technology for total hip arthroplasty (THA) was developed to improve hip function and patient satisfaction. Actis (DePuy Synthes, Warsaw, IN, USA) is a short fit-and-fill titanium stem, with a medial-collared and triple-taper (MCTT) geometry, that is fully coated with hydroxyapatite (HA). We evaluated the radiographic and clinical outcomes of the Actis Total Hip System during a mean follow-up of five years.

Background: Vitamin E-diffused highly cross-linked polyethylene (HXLPE/Vit E) is a relatively advanced material used in total hip arthroplasty (THA) but whether it shows superiority is unclear.
Objective: This meta-analysis was performed to investigate the effect of HXLPE/Vit E liners in THA.
Methods: Medline/PubMed, Embase and Cochrane Library databases were searched to retrieve studies assessing the efficacy of HXLPE/Vit E liners in THA with the design of a randomized, controlled trial.
