Which statement best describes the primary considerations guiding physical therapy management after total knee arthroplasty?

• A. Early ROM and extension goals; progressive weight bearing as prescribed; quad activation and motor control; wound care and infection surveillance; gradual progression to functional tasks and sports-specific activities per protocol; avoidance of high-impact activities until cleared.
• B. Focus only on stretching and flexibility with no strength training.
• C. Delay wound care until infection signs appear.
• D. Maintain non-weight-bearing status indefinitely.

Answer: (A)

Rehabilitation after total knee arthroplasty focuses on restoring motion and strength while protecting the healing joint and prosthesis. Achieving full or near-full extension early is critical to prevent knee stiffness and contracture, while gradually increasing knee flexion supports tissue healing and functional reaching tasks. Weight bearing is advanced according to the surgical protocol to allow safe gait training and functional loading without risking implant stability or bone integrity. Strengthening the quadriceps and retraining motor control are essential because quad weakness can limit stability and walking efficiency after surgery. Wound care and infection surveillance are paramount, given the surgical incision and implanted hardware; monitoring for redness, drainage, fever, or increasing pain helps catch issues before they threaten the prosthesis. After initial recovery, the plan progresses from basic functional tasks to more complex activities and eventually sports-specific tasks only when the patient demonstrates adequate strength, ROM, and tolerance, with clearance from the surgeon. High-impact activities are avoided until explicit confirmation to protect the implant from excessive loads and potential complications. This integrated approach, combining ROM targets, graded weight bearing, muscle reeducation, infection monitoring, and staged functional progression, best describes the typical postoperative physical therapy management after knee replacement.
