Program Overview — Knee Post-Fracture Rehabilitation, Beginner (4 Weeks)
This guide is for people recovering from a knee fracture who are new to structured rehabilitation. Over four weeks you will work gently toward less swelling, better knee bending and straightening, stronger thigh muscles, and more confident walking, with the goal of building a safe foundation you can progress from with your clinician's guidance.
Before You Start
Always warm up before activity and cool down afterward, and stop if pain increases. Because severe osteoporosis is listed as a contraindication, this program must be cleared and supervised by your clinician, since some loading and manual techniques may not be safe for you. Stop and call your clinician if you have sudden sharp or worsening pain, new swelling, a knee that gives way, numbness, calf pain or swelling, or signs of infection such as warmth, redness, or fever.
Weekly Structure
You will do four sessions each week, about forty-five minutes each, using a tennis ball, knee brace, and TRX straps. The plan moves through four gentle phases: week one protects the knee, week two adds early movement, week three builds controlled loading, and week four begins early strengthening. Expect slow, steady changes rather than big jumps, and let your clinician confirm when you are ready to move ahead.
What a Typical Session Looks Like
Each session follows warm-up, main work, then cool-down. Your warm-up might include easy range-of-motion and walking practice with your brace and assistive device. Main work may include gentle quadriceps activation, straight leg raises, soft tissue work with the tennis ball, patellar mobilization, and supported TRX exercises such as assisted squats or balance holds. Cool-down includes stretching and ice or cold compression as advised. Electrical stimulation and manual therapy are applied by your clinician or as directed.
Tracking Progress
Your clinician uses phase-specific criteria, such as swelling close to the other knee, comfortable knee bending ranges, visible thigh muscle activation, and steady balance, to decide when you move to the next phase. Outcome measures including the Lysholm, IKDC, KOS-ADLS, pain scale, knee range-of-motion measurement, and single leg stance test are repeated over time to show trends and guide your plan, not to set strict cutoffs on your own.
Recovery and Self-Care
Use ice or cold compression as advised to help with pain and swelling, and rest when your knee feels irritated. Follow your brace and walking-aid instructions, and avoid pushing through pain that worsens during or after sessions. Do not adjust medications yourself. Red flags to report promptly include increasing pain or swelling, knee instability, calf pain or swelling, numbness, or signs of infection.
Recovery phases
Knee joint swelling reduced to <2cm circumference difference from contralateral side,Passive knee flexion range of motion 0-45 degrees achieved without pain,Quadriceps activation visible with voluntary contraction,Knee is able to tolerate light weight-bearing as tolerated with assistive device,MCL/LCL medial-lateral knee stability maintained with grade I stress test,Patellar mobility within normal limits (glides superiorly, inferiorly, medially, laterally)
→ Advance to: Week 2-3
Knee flexion range of motion 0-75 degrees achieved,Full knee extension range of motion (0 degrees) achieved,Able to perform straight leg raise without knee lag,PCL tibial insertion site tolerance for posterior stress progressing,Meniscus healing status allows for limited weight-bearing flexion activities,Cartilage fracture site tolerance for controlled loading
→ Advance to: Week 3-4
Knee flexion range of motion 0-90 degrees with comfortable weight-bearing,Quadriceps strength 3/5 or better on manual muscle testing,Hamstrings and quadriceps co-contraction achieving knee joint stability,ACL graft/fixation site tolerance for progressive loading exercises,LCL lateral knee structures tolerance for varus stress in neutral extension,Patellofemoral joint tolerance for closed chain knee extension to 45 degrees
→ Advance to: Week 4+
Knee range of motion 0-110 degrees flexion,Weight-bearing progressed to full with normal gait pattern,Quadriceps strength 3+/5 with ability to perform mini squat to 30 degrees,Meniscus status permits controlled pivoting activities in limited range,Cartilage surface tolerance for low-impact loading activities,Knee joint proprioception demonstrating balance on affected leg for 10 seconds with eyes closed
