Program Overview This is a gentle, structured rehabilitation guide after knee tendon repair surgery. It uses simple equipment—a tennis ball, balance pad, and cable machine—across a 7-week plan. The aim is to help you rebuild strength, motion, and confidence safely, with your clinician guiding the pace.

Who This Is For and the Goal This program suits adults recovering from knee tendon repair who are cleared to begin guided rehab. It is also helpful for people who are new to exercise-based recovery. The overall goal is to restore knee movement, quadriceps and hamstring strength, balance, and daily function without reinjuring the repair.

Before You Start Please review this plan with your physical therapist or surgeon before starting. It is a guide, not a replacement for in-person care. Your clinician will confirm your starting point and adjust exercises to your body.

Safety Notes and When to Stop Do not start if you have active inflammation, severe pain, or a recent fracture. Stop and call your clinician if you notice sharp or worsening pain, sudden swelling, heat or redness, fever, new numbness, or a feeling that the knee "gave way." Use your brace and crutches exactly as instructed until you are cleared to progress. Listen to your body and never push through pain.

Weekly Structure Four sessions per week, about 45 minutes each, across 7 weeks. We build gradually: early weeks focus on protecting the repair and gentle motion, middle weeks add controlled strengthening and balance, and later weeks progress toward more advanced strength and function. Each phase has clear checkpoints before moving on.

How the 7 Weeks Are Organized The plan moves through phases—protection and pain control, controlled motion, strengthening, then advanced strengthening. You will typically spend a few sessions per phase, meeting the checkpoints before progressing. Expect a mix of range-of-motion work, strengthening with the cable machine and tennis ball, balance work on the pad, and pool-based sessions if available. Everything is adjusted to your comfort and clinician's advice.

What a Typical Session Looks Like Each session follows a steady rhythm: warm-up, main exercises, then cool-down. The main work pairs motion, strength, and balance tasks using your equipment. Your therapist may include aquatic therapy and blood flow restriction training where suitable and supervised.

Warm-Up, Main Work, Cool-Down Begin with gentle warm-up such as easy knee bending and light cycling or walking as cleared. Main work may include quadriceps and hamstring resistance on the cable machine, patellar mobilization with a tennis ball, balance drills on the pad, and controlled motion exercises. Cool-down with slow stretching and quiet breathing. Always warm up before and cool down after to reduce irritation.

Tracking Progress Use your clinical checkpoints and outcome measures—such as the Lysholm Knee Score, IKDC form, single leg hop distance, quadriceps strength comparison, KOS-ADLS, and Tegner scale—to see how you are improving. These are tools your clinician uses, not self-diagnostic cutoffs.

How Progression Works Your clinician uses phase checkpoints and outcome measures to decide when to advance. Meeting a checkpoint means your knee tolerates the current load without extra pain or swelling. Progress is gradual, not a race. If a checkpoint is not met, you simply spend more time in that phase; your therapist adjusts exercises to keep you moving safely.

Recovery and Self-Care Rest, ice if advised, and elevate as needed. Keep to your brace and walking aids until cleared. Stay hydrated, eat well, and sleep enough to support healing. Follow your clinician's guidance on activity and avoid overloading the knee.

Pain Management Cautions and Red Flags Mild soreness that settles with rest is common. Do not use this program to push through severe pain. Avoid unapproved medications or supplements—ask your clinician. Seek urgent care for worsening swelling, fever, chest pain, or calf pain and swelling, which can signal serious problems.

Frequently asked questions

How much soreness is normal after sessions?
Mild soreness that eases within a day is generally acceptable, but sharp or lasting pain is not. Report any increase in pain or swelling to your clinician.
Can I skip the brace or crutches early?
No—use them as instructed until your clinician clears you. Progressing too soon can stress the repair.
Do I need all the equipment to benefit?
Most exercises can be adapted, but the cable machine and balance pad help build strength and control. Ask your therapist for safe substitutes if needed.
