Patellofemoral pain refers to pain under and around your kneecap. Patellofemoral pain often comes from strained tendons and irritation or softening of the cartilage that lines the underside of the kneecap. Common symptoms include a dull aching pain underneath the kneecap while walking up or down stairs, squatting, kneeling, and sitting with your knees bent for a long period of time. Non-surgical treatment consists of rest, ice, compression, and elevation (RICE protocol); with emphasis on reduction of inflammation, improved flexibility and strengthening of the muscle groups responsible for patellar tracking. Surgery may be indicated if conservative treatment fails, and may include a cartilage debridement or treatment of patellar instability when applicable.
