Movement pattern biofeedback training after total knee arthroplasty: a randomized controlled trial.

Objective: Habitual movement compensations, such as decreased surgical peak knee extension moments (pKEM), persist years after total knee arthroplasty (TKA), are linked to poorer recovery, and may influence contralateral osteoarthritis (OA) progression. The purpose of this randomized clinical trial was to determine if a movement training program (MOVE) improves movement quality and recovery after TKA compared to a standardized rehabilitation program without movement training (CONTROL).

Methods: One hundred thirty-eight individuals were randomized to either MOVE or CONTROL groups after TKA.

The Impact of Patient Resiliency on Successful Same-Day Discharge and Postoperative Outcomes in Primary Total Hip and Knee Arthroplasty.

Background: Total hip (THA) and knee arthroplasty (TKA) rates in the outpatient setting continue to increase in the United States. Patient resiliency is one facet surgeons may consider when determining whether a patient would make a suitable candidate for same-day discharge (SDD). This study examined the relationship between resilience and success of SDD in patients undergoing primary THA and TKA.

Re-revision Extensor Mechanism Reconstruction Because of Nonunion and Tendon Failure After Total Knee Arthroplasty.

Extensor mechanism (EM) disruption after total knee arthroplasty (TKA) is devastating, especially in cases of re-rupture. A 67-year-old man with diabetes had patellar tendon rupture after revision TKA and then had migration of the bone block after Achilles tendon allograft with bone block (ATBB) augmentation with cerclage. A third reconstruction was performed with open reduction and internal fixation and high-strength braided suture augmentation.

Roles of collagen cross-links and osteon collagen/lamellar morphotypes in equine third metacarpals in tension and compression tests.

Many bones experience bending, placing one side in net compression and the other in net tension. Because bone mechanical properties are relatively reduced in tension compared with compression, adaptations are needed to reduce fracture risk. Several toughening mechanisms exist in bone, yet little is known of the influences of secondary osteon collagen/lamellar 'morphotypes' and potential interplay with intermolecular collagen cross-links (CCLs) in prevalent/predominant tension- and compression-loaded regions.

Antiphospholipid Syndrome Increases Postoperative Complications After Total Hip and Knee Arthroplasty.

Background: Antiphospholipid syndrome (APS) is a systemic autoimmune condition that predisposes patients to venous thromboembolism (VTE). Although many studies have explored risk factors for VTE after joint reconstructive procedures, the impact of APS is still unclear.

Materials And Methods: A retrospective cohort study was conducted using TriNetX, a health care database that includes 442,494 patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA).
