Program Overview This is an 11-week, beginner-level rehabilitation guide for recovery after knee tendon repair. It combines guided strengthening, balance work, and hands-on therapy techniques. Sessions are designed to be performed under the supervision of your physical therapist or surgeon, who will adjust the plan to your individual healing.

Who This Program Is For and Its Goal This program is for people recovering from knee tendon repair surgery who are cleared by their surgeon to begin structured rehabilitation. The goal is to safely rebuild quadriceps, hamstring, and hip strength, restore knee motion, and improve balance so you can return to everyday activities with confidence. Progress is gradual and guided by your clinician.

Before You Start Please review this guide with your physical therapist or surgeon before beginning. They will confirm your starting point, check your brace settings, and supervise techniques like electrical stimulation, blood flow restriction, and manual therapy. Do not begin if you have an active infection or a recent fracture near the knee, as these require medical clearance first.

Safety Notes and When to Stop Follow your clinician's brace and weight-bearing instructions closely. Stop an exercise and contact your care team if you notice increasing swelling, warmth or redness, fever, new or worsening pain, numbness, or a knee that gives way. Avoid overloading the knee and keep your spine neutral during exercises. Never push through sharp pain—discomfort should ease, and your therapist will guide safe limits.

Weekly Structure Plan for four sessions each week, about 45 minutes each, across all 11 weeks. Your therapist will set the pace and may combine supervised visits with home sessions. Equipment includes a knee brace, weight vest, pull-up bar, therapy putty, and resistance bands, used only as your clinician directs.

How the Plan Is Organized The 11 weeks move through phases: early protection, then early motion, and onward to gradual strengthening and balance. In plain terms, you start gently protecting the repair, then add controlled movement, then build strength and stability. Your therapist decides when to advance based on how your knee responds, not the calendar alone.

What a Typical Session Looks Like Each session follows a simple pattern your therapist will tailor: warm-up, main strengthening and balance work, then cool-down. You will use the listed equipment under supervision, and techniques like electrical stimulation or blood flow restriction will be applied only by your clinician. Finish every session with a cool-down as advised.

Warm-Up, Main Work, and Cool-Down Warm-ups may include gentle movement and low-resistance band work to prepare the knee. Main work focuses on quadriceps, hamstring, and hip abductor strengthening, plus balance on unstable surfaces, using putty, bands, the weight vest, or the pull-up bar as appropriate. Cool-down includes gentle stretching and settling, always following your therapist's guidance to avoid overloading.

Tracking Progress Your therapist will track your progress using standardized measures like the IKDC, Lysholm, and KOOS questionnaires, strength testing, single-leg hop distance, and knee range-of-motion measurements. These help show improvement objectively and guide safe decisions. Keep a simple log of symptoms and exercises between visits to share with your care team.

How Progression Criteria Work You move to the next phase only when your clinician confirms specific readiness signals, such as controlled pain, improving motion, stable knee ligaments, and visible muscle activation. Outcome measures add context but do not replace clinical judgment. This staged approach protects the repair while encouraging steady, safe gains.

Recovery and Self-Care Rest, good sleep, and gentle activity between sessions support healing. Avoid overloading the knee and follow your brace schedule. Keep incisions clean and watch for signs of infection. Your therapist may use manual therapy, such as patellar mobilizations and soft tissue work, to help motion and comfort—these are performed by your clinician.

Pain Management and Red Flags Discuss any pain or medication questions with your clinician; this guide does not provide medication advice. Rest when swelling increases, and avoid pushing through sharp pain. Seek prompt care for fever, spreading redness, wound drainage, sudden severe pain, or a knee that gives way. Your care team will help you adjust safely.

Frequently asked questions

Will I be in a brace the whole time?
Yes, early on your knee brace is used to protect the repair, and your clinician will gradually adjust or wean it as you meet milestones. Follow their specific brace and weight-bearing instructions.
Can I do these exercises at home?
Many exercises can be done at home once your therapist teaches safe technique and sets your limits. Some techniques, like electrical stimulation, blood flow restriction, and manual therapy, are supervised in clinic.
What if my knee swells after a session?
Mild swelling that settles with rest and elevation can be normal early on, but increasing or persistent swelling means you should ease off and tell your clinician. They will adjust your program to keep healing on track.
