This article is a summary of a symposium on knee stiffness in primary and revision total knee arthroplasties presented at the 2024 American Association of Hip and Knee Surgeons annual meeting. The purpose of this article was to provide an overview of the genetics of arthrofibrosis, preoperative and perioperative risk factors associated with arthrofibrosis, ways to optimize modifiable risk factors, and early and late treatment options for stiffness and when it fails to improve with initial interventions. LEVEL OF EVIDENCE: V.

Introduction: the presence of implants that occupy the femoral canal is frequent in patients undergoing ipsilateral total knee replacement (TKR). The use of electronic alignment and robotic assistance make intramedullary alignment unnecessary and could be adequate in situations with an occupied femoral canal (OFC).
Material And Methods: we present a prospective cohort of 25 patients who underwent robotic alignment TKR and had prior ipsilateral surgery in the femur that resulted in occupied femoral canal.

Introduction: The management of bleeding and coagulation after total knee arthroplasty (TKA) has long been recognised as a significant challenge for orthopaedic surgeons. Despite the notable success of empirical anticoagulation in preventing venous thromboembolism (VTE) following TKA, the increased risk of postoperative bleeding has also raised extensive concern. Ecchymosis, as one of the most common manifestations indicating postoperative bleeding, holds the potential to indicate the balance of bleeding and hypercoagulation.

Background: Several studies have investigated the risk of complex regional pain syndrome (CRPS) and its prevention with vitamin C. However, evidence regarding the effectiveness of vitamin C for prevention of CRPS development or recurrence after total knee arthroplasty (TKA) is lacking.
Methods: This retrospective single-center observational cohort study, which utilized propensity-score matching (PSM), was conducted from January 2017 to December 2021.

Background: Total knee arthroplasty (TKA) is a surgical procedure that induces intense acute postoperative pain, but the mechanisms that amplify post-TKA pain remain incompletely understood. Endocannabinoids, such as 2-arachidonoylglycerol (2-AG), are endogenous lipids that can produce antinociceptive effects. However, hydrolysis of 2-AG by monoacylglycerol lipase (MAGL) generates arachidonic acid, the precursor to a host of eicosanoids that enhance pain.
