Program Overview Intermediate Knee Post-Fracture Rehabilitation (21 Weeks)

This program is for people recovering from a knee fracture who have moved past the earliest healing stage and are ready to build strength, balance, and function. Over 21 weeks, twice a week for about 30 minutes, you'll work toward walking, climbing stairs, and moving through daily life with more confidence. The goal is a steady, safe return to activity—not speed. Your clinician will adjust the pace to your body, and progress depends on meeting milestones, not just the calendar.

Before You Start

Only begin or continue this program under your clinician's supervision. Do not exercise if you have active inflammation, an open or healing wound that has reopened, an unstable fracture fixation, or a known risk of blood clots—your clinician must clear these first. Always warm up before activity. Stop right away and contact your clinician if pain keeps increasing, swelling rises, the knee gives way, or you notice calf pain, warmth, or shortness of breath.

Weekly Structure

The plan runs 21 weeks with two sessions per week, about 30 minutes each, using a pull-up bar and foam roller. It moves through four broad phases—protection and pain control, early mobilization, strengthening, and advanced rehabilitation—each building on the last. You advance when you meet the milestones for your current phase, not simply when weeks pass. Sessions blend strengthening, closed-chain functional work, balance, and eventually agility, with aquatic therapy used early if available.

What a Typical Session Looks Like

Start with a warm-up to prepare the knee and improve blood flow. The main work includes progressive resisted exercises for the quadriceps and hamstrings, closed kinetic chain movements for functional strength, and balance training—using the pull-up bar for safe support during single-leg stance and the foam roller for gentle mobility and control work. Cool down with easy movement and light stretching. Keep the pattern consistent each session so your body adapts gradually.

Tracking Progress

Your clinician uses the phase progression criteria—things like knee extension, swelling, strength grades, balance time, and hop symmetry—to decide when you're ready to move forward. These are checked alongside formal outcome measures: the IKDC, Lysholm, Tegner, Single Leg Hop Test, Quadriceps Index, and KOOS. Together they show whether strength, function, and confidence are improving, and help your clinician adjust the plan if progress stalls.

Recovery and Self-Care

Expect some soreness after new activity, but pain that steadily worsens is a signal to ease off. Rest the knee when it feels swollen or irritated, and follow your clinician's guidance on ice and activity. Watch for red flags: increasing swelling, a knee that gives way, calf pain or warmth, chest pain, or shortness of breath—seek care promptly if these occur. Do not push through sharp pain or use this guide to manage medications on your own.

Recovery phases

Week 1Protection and Pain Control

Quadriceps activation with <20% extension lag on straight leg raise,Joint effusion < 30ml compared to contralateral knee,Patellar mobility 2/4 planes (superior-inferior, medial-lateral),Weight-bearing tolerance at 25% body weight with assistive device,Full passive knee extension equal to contralateral side,MCL/LCL medial-lateral joint opening <5mm at 0 degrees flexion

→ Advance to: Phase 2 - Early Mobilization

Week 4Early Mobilization

Frequently asked questions

How hard should I push during exercise?
Aim for controlled effort where you can keep good form and pain stays manageable, easing off if it climbs. Your clinician sets the right level for your phase—progress comes from consistency, not from pushing through pain.
What if I miss sessions or progress slowly?
Missing an occasional session is fine; just resume where you left off and keep the warm-up. Progress is judged by milestones, so a slower pace simply means more time in your current phase—your clinician will guide the next step.
Can I skip ahead to harder exercises?
No—each phase builds joint protection and strength that later drills depend on. Advancing before you meet the criteria raises the risk of setbacks, so let your clinician confirm you're ready to move forward.
