Program Overview This 19-week intermediate rehabilitation program is designed for people recovering from knee tendon repair surgery who have completed initial healing and are ready for structured strengthening.

Who This Program Is For and Its Goal This plan suits patients recovering from knee tendon repair who have their surgeon's clearance to begin intermediate rehabilitation. The goal is to restore full, pain-free knee motion, rebuild quadriceps and hamstring strength, retrain balance and proprioception, and prepare you for daily activities and higher-level movement. Progress is guided by regular assessment rather than by time alone, and a supervising clinician should adjust the plan to your individual needs.

Before You Start Please review these safety considerations with your clinician before beginning any session.

Safety Notes and When to Stop Always warm up before exercise, and stop immediately if pain increases or new symptoms appear. This program is not appropriate if you have or are at risk of compartment syndrome, a serious condition involving pressure and swelling within the leg; your clinician must assess this carefully. Stop and contact your care team if you notice severe or worsening swelling, a tight or tense leg, unusual pain, numbness, or changes in sensation. Use the back brace and ankle weights only as directed by your therapist.

Weekly Structure Here is how the 19 weeks are organized across five weekly sessions of about 60 minutes each.

How the 19-Week Plan Is Organized You will train five sessions per week, roughly 60 minutes each, over 19 weeks, with your back brace and ankle weights supporting safe strengthening. The program moves through four phases: protection, early motion, strengthening, and advanced strengthening. Early phases prioritize swelling control and gentle motion, often using aquatic therapy and blood flow restriction training; later phases add balance work, electrical stimulation for the quadriceps, and isokinetic strength testing. Your clinician decides when you are ready to advance.

What a Typical Session Looks Like Each session follows a consistent warm-up, main work, and cool-down pattern.

Session Pattern Begin with a gentle warm-up to raise blood flow and prepare the knee. The main work combines your prescribed strengthening with ankle weights and back brace support, plus modalities such as blood flow restriction training or neuromuscular electrical stimulation as your therapist directs. Balance and proprioception drills on unstable surfaces are introduced as you advance. Finish with a cool-down of gentle motion and stretching. Never skip the warm-up, and adjust intensity based on how your knee responds.

Tracking Progress Your clinician will use structured tests and questionnaires to measure your recovery over time.

How Progression Criteria and Outcome Measures Are Used You move to the next phase only when you meet the criteria your clinician sets, such as controlled swelling, good knee motion, and strength close to your other leg. Outcome measures like the Lysholm Knee Scoring Scale, IKDC form, hop tests, and quadriceps strength testing help track your progress objectively. These tools guide decisions but do not replace your clinician's judgment, so never advance phases on your own.

Recovery and Self-Care Rest, elevation, and listening to your body are part of the program.

Pain Management, Rest, and Red Flags Keep pain controlled; if pain rises during activity, ease off and tell your clinician rather than pushing through. Follow your care team's guidance on medication and do not self-adjust doses. Prioritize sleep and lighter days after harder sessions. Seek urgent care for severe swelling, a tight or tense leg, chest pain, shortness of breath, or calf pain and redness, as these may signal serious complications such as compartment syndrome or blood clots.

Recovery phases

Week 1Phase 1: Protection Phase

Knee effusion minimal to none (stroke test grade 0-1),Pain controlled below 3/10 at rest with weight-bearing as tolerated,Quadriceps activation achieving full terminal extension against gravity,MCL/LCL tenderness significantly reduced, no valgus/varus laxity >5mm,Meniscus repair protection: no flexion beyond 90 degrees for first 4 weeks,Patellar mobility restored with superior/inferior glide >50%

→ Advance to: Phase 2: Early Motion Phase

Week 3Phase 2: Early Motion Phase

Knee ROM: flexion 90-110 degrees, extension 0 degrees,Quadriceps strength: able to perform straight leg raise without lag,Weight-bearing progressed to full weight-bearing with crutches,Cartilage protection: low-impact activities only, no running or jumping,PCL reconstruction: posterior tibial sag <5mm with posterior drawer test,ACL reconstruction: Lachman test grade 0-1, no pivot shift

→ Advance to: Phase 3: Strengthening Phase

Week 7Phase 3: Strengthening Phase

Knee ROM: flexion 125-135 degrees, full extension,Single leg stance balance >30 seconds without compensation,Quadriceps strength >60% of contralateral side (isokinetic at 60°/sec),Hamstring strength >70% of contralateral side,Meniscus: cleared for progressive loading, no mechanical symptoms,Patellar tendon repair: cleared for progressive loading protocol

→ Advance to: Phase 4: Advanced Strengthening

Week 10Phase 4: Advanced Strengthening

Knee ROM: full ROM equal to contralateral side,Quadriceps strength >75% of contralateral side (isokinetic at 180°/sec),Hop test >75% limb symmetry index,LCL/PLC stability: no latera l compartment gapping >3mm,Proprioception: knee joint position sense within 5 degrees of contralateral,Cartilage: tolerating progressive loading without inflammation

→ Advance to: Phase 5: Return to Activity

Week 13Phase 5: Return to Activity

Frequently asked questions

Can I skip the warm-up if I'm short on time?
No. The warm-up prepares your repaired tendon and knee for loading, and skipping it raises your risk of strain or setback. Keep it brief if needed, but always include it.
How will I know when to move to the next phase?
Your clinician uses specific strength, motion, and stability checks plus outcome measures to decide. Progress is based on meeting those criteria, not simply on how many weeks have passed.
Is it normal to feel some discomfort during exercise?
Mild discomfort that settles with rest can be expected, but increasing or sharp pain is a signal to stop and check in with your clinician. Never push through worsening pain.
