Posttraumatic arthritis (PTA) is a form of joint degeneration that occurs after physical trauma to a synovial joint. Development of PTA is multifactorial and results from mechanical damage at the time of trauma, a cell-mediated inflammatory response, and abnormal articulation due to persistent malalignment or joint instability. Although some risk factors may be unavoidable, preventing the development of PTA of the knee after intra-articular fracture (IAF) requires restoring anatomic articulation and alignment. Reconstruction with total knee arthroplasty is the treatment of choice for PTA and may be a useful primary treatment for IAF in some.

Background: Posttraumatic osteoarthritis (PTOA) is directly associated with early acute articular cartilage injury. Inhibition of cartilage destruction immediately following joint damage can effectively slow or prevent PTOA progression. Therefore, we sought to determine intervention targets and therapeutic strategies in the acute stage of cartilage injury.

Background: For complete disruption of the posterolateral corner (PLC) structures, operative treatment is most commonly advocated, as nonoperative treatment has higher rates of persistent lateral laxity and posttraumatic arthritis. Some studies have shown that acute direct repair results in revision rates upwards of 37% to 40% compared with 6% to 9% for initial reconstruction. In a recent study assessing the outcomes of acute repair of PLC avulsion injuries with 2 to 7 years of follow-up, patients with adequate tissue were shown to have a much lower failure rate than previously documented.

ACL injuries commonly lead to post-traumatic osteoarthritis (PTOA), but the underlying mechanism is not well-understood. One theorized mechanism is pathological bone remodelling following an ACL tear, for which high-resolution peripheral quantitative computed tomography (HR-pQCT) is uniquely positioned to investigate in vivo in humans. In this study, we longitudinally investigate the one-year changes in periarticular bone density and microarchitecture in the human knee following an ACL tear and reconstructive surgery using data sampled from an on-going observational cohort study.

Introduction: Destruction of the metacarpophalangeal joint can result in disabling pain and stiffness. Several therapeutic options are available, including pyrocarbon interposition implants. The primary endpoint of this study was assessment of clinical and radiographic outcomes in 34 patients treated with HAPY® pyrocarbon interposition implants (Tornier, Grenoble, France) with a minimum follow-up of 3 years.

Objective: To assess the diagnostic performance of a single Knee injury and Osteoarthritis Outcome Score (KOOS) item in evaluating the presence of knee crepitus.
Design: All 184 participants aged 18-40 years with a symptomatic knee, 9-36 months following anterior cruciate ligament reconstruction (ACLR) who were prospectively enrolled in a post-traumatic knee osteoarthritis trial (ACTRN12620001164987) were included. Participants completed the KOOS and underwent physical examination for knee crepitus at baseline.
