For a knee hyperextension, recovery from a bone bruise typically takes 6 to 12 weeks, but severe cases can occasionally take up to several months to fully heal on an MRI. Because hyperextension forcefully impacts the front of the knee joint, these injuries frequently occur on the outer side of the knee bone (lateral femoral condyle or tibial plateau) and are often accompanied by ligament sprains.
Expected Recovery Timeline
Weeks 1–3 (Acute Phase): Focus is on reducing swelling and protecting the joint. You will likely need a knee brace or crutches to limit weight-bearing activities.
Weeks 4–6 (Sub-Acute Phase): Swelling decreases and walking becomes easier. Low-impact rehabilitation begins, focusing on restoring a normal range of motion.
Weeks 7–12 (Strengthening Phase): Gentle progressive resistance training begins to rebuild the quadriceps and hamstrings.
Months 3+ (Return to Sport): High-impact activities, pivoting, and running are reintroduced only after a doctor clears you and your strength is fully restored.
