BACKGROUND: Hindfoot arthritis or significant deformity involving the ankle and subtalar joint (STJ) is a disabling condition with few salvage options. Many surgeons note a decreased STJ fusion rate compared with ankle union when a retrograde nail construct is used. The purpose of this study was to report the STJ fusion rate of tibiotalocalcaneal (TTC) arthrodesis with retrograde nail. METHODS: A chart and radiographic review was performed. TTC fusions performed in patients with osteoarthritis, posttraumatic arthritis, or deformity correction with retrograde nail fixation were included...

Hip dislocation is an important orthopedic emergency usually seen in young patients who have experienced high-energy trauma, often resulting in significant long-term morbidity. Rapid identification and reduction is critical, as prolonged dislocation increases the risk of developing avascular necrosis of the femoral head, and posttraumatic osteoarthritis is a common complication, even in the absence of associated fractures. Identification and timely management of hip dislocation are highly dependent on imaging, both at presentation and after attempted reduction...

BACKGROUND: Cryotherapy is routinely administered after sports injuries of synovial joints. Although positive clinical effects on periarticular swelling and pain have been described, the effects on the cell biological activities of cartilage and synovial cells remain largely unknown so far. HYPOTHESIS: Local hypothermia alleviates synovial reactions and prevents chondrocyte death as well as cartilage destructive processes after blunt cartilage trauma. STUDY DESIGN: Controlled laboratory study...

BACKGROUND: The study objective was to examine the effect of time and fracture severity on the undiluted synovial fluid (SF) microenvironment during the acute phase following intra-articular fracture (IAF) of the human ankle. METHODS: Ankle SF from 54 patients with an acute IAF was analyzed for concentrations of 10 cytokines, 5 matrix metalloproteinases, 2 products of cartilage catabolism, and combined products of heme metabolism. All analytes were correlated with time from fracture and further analyzed for an effect of 3 time subgroups (0-2 days, 3-9 days, and ≥10 days) corresponding to timepoints for clinical ankle fracture interventions...

BACKGROUND: Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. HYPOTHESES: (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repaired ACL correlate with the total cartilage lesion area 1 year after ACL surgery, and (2) side-to-side differences in anterior-posterior (AP) knee laxity correlate with the total cartilage lesion area 1 year postoperatively...

Arthritis of the hand can result from inflammatory arthritis, osteoarthritis (OA), or be posttraumatic and can cause pain and debilitation. Arthroplasty serves as 1 surgical option in the surgical management of arthritis and aims to create a pain-free joint with preservation of motion. Although implant arthroplasty of the proximal interphalangeal (PIP), metacarpophalangeal (MCP), and trapeziometacarpal (TMC) joints predictably produce pain relief and high satisfaction, it has historically suffered from high rates of complications...

OBJECTIVE AND DESIGN: To investigate whether endogenous damage-associated molecular patterns (DAMPs) or alarmins originated from mitochondria or nucleus stimulates inflammatory response in articular chondrocytes to cause chondrolysis which leads to cartilage degradation featured in posttraumatic osteoarthritis (PTOA). MATERIALS: Primary cultures of bovine or human chondrocytes isolated from cartilage of weight-bearing joints. TREATMENT: Chondrocytes were subjected to mitochondrial DAMPs (MTDs) or HMGB1, a nuclear DAMP (NuD), with or without the presence of an N-terminal 29 kDa fibronectin fragment (Fn-f) or proinflammatory cytokines (IL-1β and TNF-α)...

BACKGROUND: Total hip arthroplasty (THA) is now an increasingly common procedure for people sustaining acetabular fractures. The incidence of acetabular fractures among the elderly population is increasing, and contemporary treatment aims to avoid the risks of prolonged incumbency associated with poor bone stock for fixation or inability to comply with limited weightbearing in this patient group. The concept of acute hip arthroplasty as a treatment for acetabular fracture is, therefore, becoming more topical and relevant...

BACKGROUND: Traumatic injuries to the tarsometatarsal or Lisfranc joints can be complex problems associated with long-term morbidity. Currently there is no clear consensus regarding optimal fixation methods. The purpose of this study was to evaluate the association between time from injury to treatment and treatment method with outcome. It is hypothesized that patients who underwent open reduction internal fixation (ORIF) more acutely would have higher return to duty rates. METHODS: This study is a retrospective review of 171 low-energy closed tarsometatarsal dislocations and fracture dislocations in patients identified using a Department of Defense trauma registry...
