Program Overview This is a 14-week advanced rehabilitation plan for recovery after knee tendon repair surgery. It combines supervised strengthening, balance work, aquatic therapy, and sport-specific drills to help you return to demanding activity safely. You will work four sessions per week, about 45 minutes each, guided by your rehabilitation team.
Who This Program Is For and Its Goal This program is for people recovering from knee tendon repair who have been cleared by their clinician and are ready for an advanced, structured progression. The goal is to restore full knee motion, rebuild quadriceps and hamstring strength, improve balance and control, and gradually reintroduce sport-specific movement. Progress is based on your own milestones, not calendar dates alone.
Before You Start Your clinician must clear you before beginning each phase. Some of the listed equipment, such as the ankle brace, kettlebell, therapy putty, and tennis ball, should only be used once your therapist confirms they are appropriate for you. Follow your surgical and rehabilitation team's instructions at all times.
Safety Notes and When to Stop Do not proceed if you have a recent fracture, any sign of infection (increased redness, warmth, swelling, or fever), or if your range of motion has not been assessed by your clinician. Always warm up before activity. Stop and call your clinician if pain increases during or after exercise, swelling worsens, or you notice new instability, locking, or giving way.
Weekly Structure You will complete four sessions per week for 14 weeks, each lasting about 45 minutes. Sessions are grouped into phases: early protection and motion, then strengthening, then more advanced power, balance, and agility work. Your therapist will decide when you move from one phase to the next based on your progress, not simply the week number.
How the 14-Week Plan Is Organized The plan moves from gentle protection and gaining motion early on, through building strength in the middle weeks, toward balance, agility, and sport-specific control later. Equipment like the ankle brace, therapy putty, tennis ball, and kettlebell is introduced gradually under supervision. Aquatic therapy may support early weight bearing, while resistance machines and testing tools are added as you advance.
What a Typical Session Looks Like Each session follows a predictable pattern so you know what to expect. Your therapist will adjust the details to your current phase and your response to previous sessions. Consistency and good technique matter more than pushing hard, especially early in recovery.
Warm-Up, Main Work, and Cool-Down Begin with a warm-up such as easy cycling or gentle movement to prepare the knee. The main work may include progressive resistance exercises like leg press, squats, and hamstring curls, plus balance work on unstable surfaces, aquatic therapy, or agility drills depending on your phase. Cool down with gentle stretching and use the tennis ball or therapy putty for light foot and hand work as directed by your therapist.
Tracking Progress Your rehabilitation team will track your range of motion, strength, swelling, and pain alongside formal outcome measures. These include the Lysholm scale, IKDC form, KOOS, single-leg hop test, strength ratios, and Tegner activity scale. Tracking helps show whether you are ready to advance or need more time in a phase.
Using Progression Criteria and Outcome Measures You move to the next phase only when you meet the goals for your current phase, such as controlled pain, improving range of motion, and no increased swelling. Outcome measures give an objective picture of your strength and function over time. Together they help your therapist make safe, individualized decisions rather than rushing ahead.
Recovery and Self-Care Rest, sleep, and good nutrition support healing. Follow your clinician's guidance on ice, elevation, and activity between sessions. Keep to your prescribed exercises but avoid adding extra load or new activities without checking with your therapist, since doing too much too soon can set your recovery back.
Pain Management and Red Flags Some mild discomfort with activity can be expected, but stop if pain increases or swelling returns. Do not ignore signs of infection, sudden severe pain, a pop or giving way, calf swelling, or chest pain and shortness of breath. Report any of these to your clinician promptly. Medication questions should go to your prescribing clinician.
