Advanced Knee Tendon Repair Rehabilitation Program: 18-Week Guide

This program is for people recovering from knee tendon repair surgery who have been cleared by their surgeon and physical therapist to begin an advanced strengthening plan. The goal is to rebuild quadriceps and hamstring strength, restore full knee motion, and return you safely to demanding activities over 18 weeks, using equipment like barbells, resistance bands, and a rower under clinician supervision.

Before You Start

Only begin after your surgeon and physical therapist confirm your repair is ready for loading. This plan is not appropriate if you have severe osteoporosis or a risk of deep vein thrombosis (blood clots), as these raise the danger of loading and immobilization; your clinician must clear you first. Always warm up before and cool down after sessions. Stop immediately and call your clinician if pain increases, swelling worsens, or you notice calf pain, warmth, or shortness of breath.

Weekly Structure

Plan on four sessions per week, about 60 minutes each, for 18 weeks. Early weeks focus on protection and gentle motion, then build toward strengthening and advanced loading. The plan moves through four phases: protection and acute management, early motion, strengthening (around week 8), and advanced strengthening (around week 12). Expect equipment like the rower, resistance bands, and barbells to appear progressively as you advance.

What a Typical Session Looks Like

Each session follows a warm-up, main work, and cool-down pattern. Warm up on the rower at an easy pace, then do band work for the hips and knee. Main work includes progressive resistance exercises with bands and barbells, plus balance and functional drills as you advance. Cool down with gentle stretching and, where prescribed, cryotherapy with compression to manage swelling.

Tracking Progress

Your clinician uses the phase criteria to decide when you are ready to advance—for example, reaching near-full knee motion or strength close to your other leg. Outcome measures like the KOOS, IKDC, Lysholm scale, Single Leg Hop Test, and quadriceps symmetry testing help track your recovery over time. These guide decisions alongside your clinician's exam; do not advance phases on your own.

Recovery and Self-Care

Some soreness is expected, but stop if pain increases during or after exercise. Use ice with compression as advised to manage swelling, and get adequate rest between sessions. Red flags needing prompt clinician contact include sudden swelling, calf pain or warmth, chest pain, or shortness of breath. Never push through sharp pain or joint giving-way.

Recovery phases

Week 1Phase 1: Protection and Acute Management

Knee effusion minimized to <1 inch (2.5cm) above patella compared to contralateral knee,Quadriceps activation achieving volitional contraction with superior patellar glide,MCL/LCL protection: brace locked at 0-30 degrees flexion, no varus/valgus stress,ACL/PCL graft protection: weight bearing as tolerated with crutches, no open-chain hamstring loading,Patellar mobility: superior-inferior glides achievable without pain,Meniscus repair protection: no flexion beyond 90 degrees for first 4 weeks

→ Advance to: Phase 2: Early Motion

Week 4Phase 2: Early Motion

Full knee extension equal to contralateral side (0 degrees),Knee flexion to 90 degrees without pain at patellar tendon or quadriceps tendon repair site,MCL/LCL healing: valgus/varus stress test stable at 0 and 30 degrees,Quadriceps strength: manual muscle test grade 3/5 in terminal extension,Patellar mobility: full medial-lateral and superior-inferior glides,Cartilage protection: low-impact modalities only, no deep flexion squats

→ Advance to: Phase 3: Strengthening

Week 8Phase 3: Strengthening

Knee flexion 0-125 degrees with patellofemoral tracking asymptomatic,ACL/PCL stability: Lachman test grade 1 or less, posterior drawer <5mm,MCL/LCL stability: valgus/varus at 0 and 30 degrees within 5mm of contralateral,Quadriceps strength: isokinetic at 60 deg/sec >60% of contralateral,Meniscus status: no mechanical symptoms with weight-bearing flexion,Patellar tendon/quadriceps tendon: full weight-bearing without assistive device

→ Advance to: Phase 4: Advanced Strengthening

Week 12Phase 4: Advanced Strengthening

Full range of motion 0-135 degrees equal to contralateral knee,Quadriceps strength: isokinetic at 180 deg/sec >75% of contralateral limb,Hamstring strength: bilateral symmetry >80% for ACL/PCL dynamic stability,Cartilage loading tolerance: progressive loading without swelling, squat to 70 degrees,Single-leg stance balance: >30 seconds eyes closed on affected limb,Functional movement pattern: proper mechanics on step-up/down without valgus collapse

→ Advance to: Phase 5: Return to Activity

Week 15Phase 5: Return to Activity

Quadriceps strength: isokinetic >85% limb symmetry index,Plyometric readiness: double-leg jump with symmetric landing mechanics,Agility testing: 45-degree cuts and pivot without instability symptoms,MCL/LCL functional stability: lateral lunges without pain or giving way,Patellofemoral stability: squat depth >90 degrees without crepitus or anterior knee pain,Cardiovascular endurance: treadmill running at 6mph without knee swelling

→ Advance to: Return to Sport Clearance

Week 18Final Progression and Discharge

Quadriceps limb symmetry index >90% for ACL/PCL reconstructed knee,All knee ligaments: stable on Lachman, posterior drawer, valgus/varus stress tests,Functional assessment: single-leg hop for distance >90% of contralateral,Patient-reported outcome: KOOS or IKDC subjective score >80 points,No activity-limiting knee effusion 24 hours post-exercise,Return to sport testing: running, cutting, jumping at full intensity without compensation

Pain management

Cryotherapy: ice pack application 15-20 minutes every 2-3 hours for acute pain and post-exercise swelling
NSAID medication as prescribed for inflammation management around graft and tendon repair sites
Neuromuscular electrical stimulation (NMES) to quadriceps for pain modulation and muscle activation
Soft tissue mobilization: patellar mobilizations and IT band releases for posterior knee and lateral compartment
Positioning and elevation: prone lying with knee supported in extension for posterior capsule and PCL management

Frequently asked questions

Can I skip the warm-up if I am short on time?

No—always warm up before loading the knee, since cold tissues are more vulnerable to strain. Your clinician can help you shorten the warm-up safely if needed.

How do I know when to move to the next phase?

Progression depends on meeting the phase criteria and your clinician's assessment, not on the calendar alone. Your therapist will confirm readiness using strength, motion, and outcome measures.

Is it normal to have some swelling after sessions?

Mild swelling that settles with ice and rest can be expected, but increasing or persistent swelling should be reported to your clinician before continuing.
