In knee osteoarthritis rehab, which sequence best describes progression from initial management to functional improvements?

• A. Start with pain and swelling control, then ROM/flexibility, then functional training, then isotonic strengthening
• B. Start with ROM and flexibility
• C. Isotonic strengthening after ROM, then functional training
• D. Focus only on modalities

Answer: (C)

The main idea here is that knee OA rehab should move from restoring the joint’s movement to building the muscles around the knee, then practicing real-life tasks to make gains functional.

Restoring range of motion addresses stiffness and tight soft tissues, creating a tissue environment that can safely handle load. Once motion is adequate, introducing isotonic strengthening targets the muscles supporting the knee, especially the quadriceps and hip stabilizers. Strength gains help control the patellofemoral joint, reduce joint load during everyday activities, and improve functional capacity. Finally, functional training translates those physical gains into actual daily activities—walking, stairs, sit-to-stand, balance tasks—so improvements carry over to real life.

Pain and swelling management is important early to enable motion, but on its own it doesn’t produce lasting functional improvements without moving into strengthening and then task-specific practice. The sequence that starts with ROM, then progresses to strengthening, and finally to functional training best supports safe, meaningful improvements in function.
