Ultrasound-Guided Versus Landmark-Guided Injection in Knee Osteoarthritis: A Comparative Study of Pain Trajectory, Functional Recovery, and Treatment Durability
Background: Intra-articular injections are a mainstay of conservative management in knee osteoarthritis (OA). Accuracy of needle placement affects clinical outcomes, and ultrasound (US) guidance has been proposed as superior to conventional landmark-guided injection. Objective: To compare pain trajectory, functional re...
