Knee Tendon Repair Intermediate Program — Program Overview

This 15-week program is for people recovering from knee tendon repair surgery who have completed early protection and are ready for a structured, supervised intermediate phase. The goal is to gradually restore knee motion, strength, balance, and confidence in daily activities and, where appropriate, sport, using foam rollers, a rower, and TRX systems alongside clinical modalities such as CPM, electrical stimulation, patellar mobilization, and blood flow restriction training.

Before You Start

Always begin this program under the guidance of your surgeon and physical therapist, and follow any brace or weight-bearing rules you have been given. Do not start if you have an active infection, and do not push through increasing pain, new swelling, or a hot, red, or draining wound. Stop and call your clinician if pain keeps rising, your knee suddenly gives way, you lose range of motion, or you notice signs of infection such as fever or wound changes.

Weekly Structure

You will train three sessions per week for 30 minutes across 15 weeks, moving through four phases: protection and pain control, early range of motion, progressive strengthening, and advanced strengthening. Each phase introduces more movement and load as you meet your clinician's checkpoints. Equipment includes a foam roller for soft-tissue work, a rower for controlled conditioning, and TRX straps for supported strength and balance work.

What a Typical Session Looks Like

Start with a gentle warm-up such as light foam rolling away from the incision and supported range-of-motion drills. The main work combines your clinician-directed modalities, TRX-supported strength exercises, balance practice, and rower intervals as tolerated, keeping your spine neutral and avoiding sudden knee overload. Cool down with easy stretching and calm breathing, and note how your knee responded so your therapist can adjust the next session.

Tracking Progress

Your therapist uses the phase checkpoints—such as swelling, pain, range of motion, strength, and balance—to decide when you are ready to advance, rather than following the calendar alone. Outcome measures including the IKDC, Lysholm, Tegner, KOOS, Single Leg Hop Test, and Quadriceps Index are repeated at set intervals to show change over time and guide safe progression.

Recovery and Self-Care

Expect some soreness after new exercises, but pain should settle with rest and should not steadily climb. Follow your clinician's guidance on icing, elevation, and activity pacing, keep the incision clean, and avoid heavy loading or twisting early on. Seek urgent care for signs of infection, chest pain, calf pain or swelling, or a knee that becomes hot, locked, or unable to bear weight.

Recovery phases

Week 2Phase 1: Protection and Pain Control

Knee swelling reduced to <2 cm circumference difference from contralateral side,Pain level ≤3/10 at rest and ≤5/10 during CPM or passive motion,Knee flexion passive range of motion 30-45° achieved without valgus/varus stress,Quadriceps contraction visible with supine leg raise despite multiligament involvement,Surgical incision/tendon repair site healing without signs of infection, Tibiofemoral joint line tenderness decreased by 50%

→ Advance to: Phase 2

Week 4Phase 2: Early Range of Motion

Knee flexion passive range of motion 75-90° achieved without posterior tibial translation stress,Knee extension passive range of motion 0° (full extension) or -5° hyperextension achieved,MCL/LCL valgus/varus stress testing shows <5mm gapping (grade I-II),Patellar mobility superior/inferior glide 1-2 quadrants achieved,Meniscal repair protection: no flexion beyond 90° for first 4 weeks if repair performed,Quadriceps lag <10° with straight leg raise

→ Advance to: Phase 3

Week 7Phase 3: Progressive Strengthening

Knee flexion active range of motion 110° achieved,Knee extension active range of motion 0° maintained,Hamstring strength 4/5 on manual muscle testing,Quadriceps strength 3+/5 on manual muscle testing with minimal substitution,Weight-bearing tolerance full weight-bearing with brace locked in extension,Patellar tendon repair: full passive knee flexion without resisted quadriceps activation

→ Advance to: Phase 4

Week 10Phase 4: Advanced Strengthening

Quadriceps strength ≥4/5 on isokinetic dynamometry at 60°/sec,Hamstring strength ≥70% of contralateral side,Single-leg stance balance ≥30 seconds without compensation,Knee flexion strength 80% of contralateral side at 180°/sec,No patellofemoral crepitus with active knee motion,Posterior cruciate ligament load tolerance: prone knee flexion angle tolerance improved

→ Advance to: Phase 5

Week 13Phase 5: Functional Training

→ Advance to: Phase 6

Week 15Phase 6: Return to Activity

Frequently asked questions

Can I skip phases if I feel ready?
No—phase checkpoints protect the healing tendon, so progression is decided with your clinician based on measured criteria rather than how you feel on a good day.
Is it normal for my knee to swell after sessions?
Mild, temporary swelling can happen, but increasing or persistent swelling means you should ease off and check in with your therapist before continuing at the same level.
Can I use the rower every session?
Rower use depends on your phase and knee tolerance, so start with short, controlled intervals and let your therapist adjust the amount based on pain, swelling, and spinal position.
