Beginner Knee Post-Fracture Rehabilitation Program: 16-Week Guide
This program is for adults recovering from a knee fracture who are new to structured rehabilitation and have been cleared by their treating clinician to begin guided exercise. Its goal is to help you regain knee movement, rebuild thigh and leg strength, improve balance, and return to everyday activities safely over 16 weeks. You will work at your own pace, with progress judged by how your knee responds rather than by a calendar alone.
Before You Start
Do not begin if you have an open or re-opened wound, active inflammation, severe pain, or knee movement that has not yet been assessed by your clinician. Stop and contact your care team if pain increases during or after exercise, swelling rises, you feel a new catch or locking, or you cannot bear weight. Warm up before every session, keep your spine in a neutral position, and use the ankle and back braces as advised for support during standing and balance work.
Weekly Structure
Plan for two sessions per week, about 20 minutes each, across 16 weeks, using an ankle brace, back brace, suspension trainer, tennis ball, and balance pad. Early weeks focus on protecting the healing knee, reducing swelling, and gentle movement. Middle weeks add controlled motion and light strengthening, and later weeks build strength, balance, and confidence with everyday tasks. Your clinician decides when you move to the next stage based on your knee's response.
What a Typical Session Looks Like
Start with a gentle warm-up of easy knee bending, sitting knee extensions, and ankle pumps. The main work may include supported squats or leg presses with the suspension trainer, seated knee extensions, gentle balance holds on the balance pad with the back brace on, and light tennis-ball rolling for soft-tissue comfort. Cool down with slow movement and calf and hamstring stretches, then apply cold compression as directed. Keep each part short and comfortable.
Tracking Progress
Your clinician uses simple checkpoints, such as how fully you can straighten and bend your knee, swelling, tenderness, and strength, to decide when to advance. You will also complete outcome measures like the KOOS and Lysholm questionnaires, range-of-motion measurements, a single-leg hop test when appropriate, and strength testing. These track changes over time; they guide decisions but do not replace your clinician's judgment. Never progress on your own if a checkpoint has not been met.
Recovery and Self-Care
Some soreness after exercise can be normal, but increasing pain, rising swelling, warmth, or redness are reasons to ease off and check in with your clinician. Rest the knee when it feels irritated, keep using cold compression as advised, and avoid pushing through sharp pain. Seek prompt care for wound problems, fever, sudden severe pain, new locking or giving way, or calf swelling and pain.
