Program Overview This is a 22-week, twice-weekly rehabilitation program for people recovering from knee tendon repair surgery, including repairs involving the ligaments around the knee. Sessions run about 60 minutes and use a balance board and foam roller. The program blends gentle strengthening, kneecap mobility work, balance training, and cardiovascular conditioning to help you return to everyday activity safely. It is written for an intermediate level, meaning you have already started basic healing and are ready to build strength and control gradually.
Who This Program Is For and Its Goal This guide is for adults who are past the earliest healing stage after knee tendon repair and have been cleared by their surgeon or therapist to begin a supervised intermediate program. The goal is to restore knee movement, rebuild thigh and hip strength, improve balance, and safely increase activity tolerance over 22 weeks. It is not a substitute for hands-on care, and your clinical team should confirm it fits your specific repair.
Before You Start Please review this plan with your surgeon and physical therapist before beginning. Do not start if you have severe osteoporosis or if your surgical team has told you the repair is not yet stable (unstable fixation). These are important safety exclusions. Your clinician will confirm your healing stage and adjust any exercise that does not suit your repair. Always warm up before activity, and stop if pain increases rather than pushing through it.
Safety Notes and When to Stop Stop exercising and contact your clinician if you notice sharp or worsening knee pain, new swelling, a feeling of instability or "giving way," numbness, or warmth and redness around the knee. These can be warning signs that need review. Never push through pain that climbs during a session. If a movement causes more than mild discomfort, ease off and tell your therapy team. Follow any weight-bearing or movement limits your surgeon has set.
Weekly Structure You will do two sessions per week, each about 60 minutes, across 22 weeks. The plan moves through clear phases: early protection, gentle motion, early strengthening, and fuller strengthening. Each phase builds on the last, and you only advance when you meet the goals your clinician checks. A balance board and foam roller are the main tools, alongside a stationary bike or elliptical for conditioning. Expect the work to feel gradual, not rushed.
How the 22 Weeks Are Organized Think of the program in four broad phases. The first weeks focus on protecting the repair and gentle muscle activation. Around the next stage you work on regaining knee motion. Then comes early strengthening for the thigh and hip muscles. Later weeks build fuller strength, balance, and loading tolerance. Each session includes warm-up, main exercises, and cool-down. Your therapist decides when you are ready to move to the next phase based on how you are healing.
What a Typical Session Looks Like A typical session starts with a warm-up to prepare the knee and leg, moves into the main strengthening, balance, and mobility work, and finishes with a cool-down. The balance board is used for controlled balance challenges, and the foam roller helps with gentle soft-tissue work and mobility around the thigh and hip. Stationary biking or elliptical work adds cardiovascular conditioning. Your therapist will tailor the exact exercises to your stage and comfort.
Warm-Up, Main Work, and Cool-Down Begin with light biking or easy movement to warm the leg. The main work includes closed-chain strengthening such as controlled leg presses or shallow squats as cleared, kneecap mobility and taping as directed, balance-board training, and progressive hip and hamstring strengthening. Use the foam roller gently for surrounding muscles, not directly over the repair. Cool down with slow stretching and easy range-of-motion movement. Keep everything controlled and pain-free.
Tracking Progress Your clinician will track your progress using standard knee questionnaires and physical tests, including the IKDC, Lysholm, and KOOS forms, a single-leg hop test, strength-ratio testing, and knee range-of-motion measurements. These give a clear picture of how your knee is recovering beyond how it feels day to day. Regular tracking helps your team spot problems early and celebrate real gains. Keep your own notes on pain and function to share at visits.
Using Progression Criteria and Outcome Measures You move between phases only when your clinician confirms you meet that phase's goals, such as reaching certain knee motion, strength, or balance milestones. These checks keep progression safe and matched to your healing. Outcome measures like the KOOS and hop test show how your function compares over time. Do not advance on your own; let your therapy team interpret the results and adjust the plan. Slow, verified progress protects your repair.
Recovery and Self-Care Recovery happens between sessions too. Get enough rest, keep swelling controlled as advised, and stay generally active within your limits. Use ice or elevation only as your clinician recommends. Keep doing your home exercises as prescribed, and avoid sudden increases in activity. Good sleep and steady pacing help your knee tolerate the strengthening work. Tell your team about any new symptoms rather than working around them.
Pain Management Cautions and Red Flags Mild, settling discomfort during exercise can be normal, but pain that rises and stays up is a signal to back off. Do not use this guide to make medication decisions; ask your clinician or pharmacist about pain relief. Red flags include sudden severe pain, marked new swelling, fever, calf pain or swelling, or the knee giving way. If any of these occur, stop and seek medical advice promptly.
