Program Overview This is an eight-week, beginner-level rehabilitation guide for recovery after knee tendon repair. It combines supervised movement, strengthening, and supportive therapies to help you regain motion and confidence safely. It is general education, not a personal prescription.

Who This Program Is For and Its Goal This program is for adults starting rehabilitation after knee tendon repair who have been cleared by their surgeon or physical therapist to begin guided exercise. The goal is to protect the repair while gradually restoring knee movement, leg strength, balance, and walking tolerance, using equipment safely at an easy starting level.

Before You Start Confirm with your surgical and rehabilitation team that this plan suits your repair, your stage of healing, and your home or gym setup. A clinician should check your knee, teach the exercises, and adjust effort. Do not start if you have active or worsening inflammation in or around the knee.

Safety Notes and When to Stop Avoid pushing through sharp pain, new swelling, warmth, or redness around the knee, as these can signal irritation. Stop and call your clinician if you notice sudden increased pain, a giving-way feeling, fever, calf swelling, chest pain, or shortness of breath. Warm up before activity and avoid overloading the knee with heavy resistance or deep bending too soon.

Weekly Structure Plan for five short sessions each week, about twenty minutes each, with rest or lighter days as needed. Early weeks emphasize gentle motion and protection; middle weeks add controlled strengthening and balance; later weeks build tolerance with the barbell and elliptical as your clinician allows.

How the Eight-Week Plan Is Organized The plan moves through protection and early mobility, then controlled motion, then gradual strengthening. Sessions use the elliptical for low-impact warm-ups and aerobic work, and the barbell only for light, supervised strength work when appropriate. Your therapist may also use supportive therapies such as CPM, electrical stimulation, ultrasound, water exercise, or blood flow restriction within their clinical judgment.

What a Typical Session Looks Like Each session follows a warm-up, main work, and cool-down pattern. Expect gentle motion first, then targeted strengthening, then easy aerobic work and settling down. Keep the effort comfortable and stop short of strain.

Warm-Up, Main Work, and Cool-Down Begin with easy elliptical pedaling or guided knee bending to warm the joint. Main work may include light barbell-supported strength exercises, balance practice, and approved mobility drills. Cool down with slow walking, gentle stretching as advised, and elevating the knee if swelling tends to increase.

Tracking Progress Keep a simple log of sessions, pain, swelling, and what felt easier over time. Share it with your clinician so they can compare against the progression criteria and outcome measures.

How Progression and Outcome Measures Work Your clinician uses criteria such as comfortable knee bending range, straightening, visible muscle contraction, low swelling, and stable ligaments to decide when to advance. Standard measures like KOOS, Lysholm, hop distance, Timed Up and Go, strength testing, and activity scales track change over time. These guide decisions; they are not targets you must hit alone.

Recovery and Self-Care Recovery after tendon repair takes patience. Prioritize sleep, hydration, and balanced meals, and follow your team's guidance on ice, elevation, and activity between sessions. Keep the knee moving gently unless told otherwise, and avoid long periods of stiffness or sudden increases in load.

Pain Management Cautions and Red Flags Use pain as a guide: mild discomfort that settles is common, but sharp or escalating pain is a signal to ease off. Do not add medication or anti-inflammatory products without asking your clinician, especially with healing tissue. Seek urgent care for fever, spreading redness, calf swelling, or breathing problems.

Recovery phases

Frequently asked questions

Can I skip the elliptical and just do strengthening?
Ask your therapist first, because the elliptical often provides a safe warm-up and low-impact circulation that supports healing. Replacing it entirely may change how your knee tolerates the session.
How hard should the barbell work feel?
Keep it light and controlled, well below maximal effort, and only use loads your clinician approves. The goal early on is movement quality, not heavy lifting.
What if my knee swells after a session?
Mild swelling that settles with rest and elevation can be normal, but increasing or persistent swelling means ease back and check in with your clinician. They may adjust your program or supportive therapies.
