Program Overview This is a structured, five-week intermediate rehabilitation guide designed for people recovering from knee tendon repair surgery. It blends hands-on techniques, guided exercise, and supportive therapies to help you rebuild strength, motion, and confidence safely.

Who This Program Is For And Its Goal This program suits patients past the initial healing stage of a knee tendon repair who are ready for more active work, with a clinician's approval. The goal is to restore knee movement, activate and strengthen the surrounding muscles, improve balance, and return you toward everyday activities without overloading the healing tissue.

Before You Start Please review this guide with your supervising clinician before beginning. Your therapist should confirm you are past the acute phase, help set your starting level, and check that each activity suits your knee at this stage.

Safety Notes Do not start if your knee is in an acute inflammation flare or you have severe pain. These are signs to pause and check in with your clinician. Stop and call your care team if you notice sharp or worsening pain, sudden swelling, a knee that gives way, numbness, or a feeling that something is wrong. Never push through pain to finish a set, and keep your spine neutral during all exercises.

Weekly Structure Each week includes four sessions of about sixty minutes. Sessions are organized into a warm-up, main strengthening and movement work, and a cool-down. Equipment is simple: therapy putty and a tennis ball, plus access to the listed modalities under supervision.

How The Plan Is Organized The five weeks move through four broad phases: protection and early management, early motion and muscle activation, progressive strengthening, and advanced strength with functional training. Each phase builds on the last, and you only advance when you meet the stated criteria. Expect the later weeks to feel more challenging than the first.

What A Typical Session Looks Like Each session follows a predictable pattern so you know what to expect. Your clinician may adjust the mix based on how your knee responds that day, but the overall flow of prep, main work, and recovery stays consistent.

Warm-Up, Main Work, Cool-Down Begin with gentle movement to warm the knee and prepare the muscles. Main work may include aquatic therapy for early motion with less joint load, guided quadriceps activation, soft tissue work, and strengthening using therapy putty and a tennis ball for controlled drills. Cool-down includes gentle stretching and settling to calm the knee afterward; always finish with a cool-down as noted.

Tracking Progress Your clinician will track how your knee moves, how strong it feels, and how it handles daily tasks. Simple measures and standardized questionnaires help show whether you are ready to move to the next phase, so bring any changes in symptoms to each visit.

How Progression Criteria Are Used You advance to the next phase only when you meet the listed goals, such as reaching specific knee motion, showing a strong muscle contraction, or keeping swelling low. Outcome measures like the KOOS, Lysholm, and balance or hop tests give a fuller picture of recovery and guide timing of harder activities. These targets are decided with your clinician, not on your own.

Recovery And Self-Care Rest, good sleep, and gentle movement between sessions support healing. Follow your clinician's guidance on activity and avoid overloading the healing tendon. Keep the knee moving gently and use ice or elevation as advised for comfort.

Pain Management Cautions And Red Flags Use caution with pain: mild, settling discomfort may be acceptable, but sharp or rising pain is not. Do not push through severe pain or obvious swelling. Seek prompt advice for a hot, very swollen knee, new giving-way, fever, or pain that keeps worsening despite rest, and never add medication on your own without asking your care team.

Recovery phases

Week 1Protection & Acute Management

Full knee extension achieved with minimal extensor lag,Patellar mobility maintained with superior/inferior glides,Quadriceps contraction with visible quadriceps tendon activation,Knee swelling reduced to <2cm quadriceps circumference difference,MCL/LCL pain-free with valgus/varus stress testing grade I or less,Weight bearing as tolerated with crutch assistance

→ Advance to: Week 2: Early Motion & Neuromuscular Activation

Week 2Early Motion & Neuromuscular Activation

Knee flexion progressed to 90 degrees without posterior knee pain,Hamstring co-contraction achieving >70% quadriceps activation,Meniscus protection with avoidance of deep flexion angles >90 degrees,Patellofemoral tracking normalized without lateral deviation,ACL/PCL protection with avoidance of anterior/posterior tibial translation,Isometric quadriceps hold >10 seconds at 60 degrees knee flexion

→ Advance to: Week 3: Strengthening & Progressive Loading

Week 3Strengthening & Progressive Loading

Knee flexion 0-110 degrees with patellar tendon graft protection,Closed chain exercises to 45 degrees knee flexion for ACL/PCL protection,Quadriceps strength >50% contralateral side with no extensor mechanism compensation,MCL/LCL healing confirmed with valgus/varus stress at 0 and 30 degrees,Meniscus healing sufficient for controlled pivoting activities avoided,Cartilage protection with low-impact exercises avoiding high compressive forces

→ Advance to: Week 4: Advanced Strengthening & Functional Training

Week 4Advanced Strengthening & Functional Training

Frequently asked questions

How hard should I push during exercises?
Push only to a level your clinician approves, keeping pain mild and settling, and stop if it sharpens. Never work through severe pain or a knee that feels unstable.
What if my knee swells after a session?
Some mild swelling can happen, but rising swelling is a signal to ease back and tell your clinician. Use rest and elevation as advised and let them decide whether to adjust your program.
Can I skip ahead to harder exercises?
No, it is safer to progress only when you meet the phase criteria with your clinician's guidance. Rushing can overload the healing tendon and set your recovery back.
