Knee Post-Fracture Beginner Rehab Program — Overview This is a 4-week, beginner-level rehabilitation guide for people recovering from a knee fracture. It combines gentle range-of-motion work, strengthening for the thigh muscles, balance training, and practice with everyday movements. You will use a foam roller, an elliptical machine, and a balance pad, and each session takes about 20 minutes, twice a week.

Who This Program Is For and Its Goal This program is for adults who have had a knee fracture and are early in recovery, with clearance from their treating clinician to begin guided exercise. The goal is to gradually restore knee movement, rebuild thigh and hamstring strength, improve balance, and return to safe walking and stair use. Progress is steady and cautious rather than fast.

Before You Start Check with your doctor or physical therapist before starting, and confirm your fracture is stable enough for this level of activity. Have your equipment ready, wear supportive shoes, and exercise on a clear, non-slip surface. A therapist should supervise your first sessions if possible, especially if you use walking aids or have had surgery.

Safety Notes and When to Stop This program is not suitable if you have compartment syndrome, severe osteoporosis, or an unstable fracture fixation — your clinician will tell you if any of these apply. Stop and call your clinician if you get sharp or worsening knee pain, new swelling, numbness, a feeling of instability, calf pain, or pain that does not settle with rest. Warm up before every session and avoid overloading the knee.

Weekly Structure You will do two sessions each week for four weeks, about 20 minutes per session, using a foam roller, elliptical, and balance pad. Week 1 focuses on gentle motion and pain control; week 2 adds more active movement; week 3 builds controlled loading and better walking; week 4 adds early strengthening and balance. Your therapist decides when you move to the next phase.

How the Plan Progresses Each week has a theme that builds on the last. Early weeks emphasize protecting the healing knee while keeping it moving; later weeks add strength and balance as your knee tolerates more. You only advance when you meet the readiness signs for your current phase — for example, good muscle activation, reduced swelling, and comfortable range of motion — rather than by the calendar alone.

What a Typical Session Looks Like Every session follows the same simple pattern: a warm-up, the main exercises, and a cool-down. The main work includes passive and active-assisted range-of-motion exercises, quadriceps and hamstring strengthening, balance practice, and functional training like walking and stairs. Keep the pace comfortable and rest between exercises as needed.

Warm-Up, Main Work, and Cool-Down Begin with a few minutes of easy elliptical pedaling to warm the muscles. Then do your range-of-motion and strengthening exercises, using the foam roller for gentle soft-tissue work where your therapist advises, and the balance pad for weight shifting and single-leg stance practice. Finish with slow, easy movement and gentle stretching as a cool-down to help the knee settle.

Tracking Progress Keep a simple log of your sessions, noting pain levels, how far you can bend and straighten your knee, and how balance and walking feel. Your clinician will use measures such as the KOOS questionnaire, a pain rating scale, knee range-of-motion, single-leg stance time, the Timed Up and Go test, and thigh strength testing to track your recovery objectively.

How Progression Criteria Are Used Your therapist uses the weekly readiness signs — like achieving a full quadriceps contraction, reduced swelling, comfortable range of motion, and good strength — to decide when you move to the next phase. Outcome measures add an objective picture over time. Do not push ahead on your own; let your clinician confirm each step forward.

Recovery and Self-Care Recovery takes time, so be patient and consistent. Rest the knee when it feels irritated, keep up gentle movement, and use ice or elevation as your clinician advises. Stay active within comfort, keep follow-up appointments, and tell your care team about any changes in pain, swelling, or how the knee feels during daily activities.

Pain Management and Red Flags Mild, manageable discomfort during exercise is common, but stop if pain increases sharply or persists afterward. Do not push through swelling or a knee that feels unstable. Seek urgent care for severe pain, sudden large swelling, calf pain or swelling, numbness, or a knee that gives way — these need prompt clinician review rather than continued exercise.

Recovery phases

Week 1Protection and Pain Control

Quadriceps activation with quad sets achieving full quad contraction,Patellar mobility maintained with superior-inferior glides,Tibiofemoral joint swelling reduced to <2cm circumflex difference,MCL/LCL healing phase - no valgus/varus stress,Patellofemoral joint pain <3/10 during passive ROM,Meniscus healing - no deep flexion pain or clicking

→ Advance to: Early Motion Phase

Week 2Early Motion

Passive knee flexion ROM 0-90 degrees achieved,Active knee extension to 0 degrees (full extension),Quadriceps strength MMT 3/5 or greater,Hamstring activation without meniscus pain,Cartilage tolerance to low-load weight bearing,Patellar tendon loading without anterior knee pain

→ Advance to: Progressive Loading Phase

Week 3Progressive Loading

Passive knee flexion ROM 0-115 degrees,Weight bearing tolerance to 50% body weight,ACL/PCL graft or healing tolerance to controlled loading,Medial/lateral knee stability to varus/valgus stress testing,Functional gait pattern without antalgic gait,Cartilage loading progression without increased effusion

→ Advance to: Early Strengthening Phase

Week 4Early Strengthening

Frequently asked questions

How much pain is okay during these exercises?
Mild discomfort that settles quickly with rest is generally acceptable, but sharp or lingering pain is a sign to ease off. Always check with your clinician about what level of discomfort is safe for your knee.
Can I skip sessions or speed up the weeks?
It is better to stay consistent with your two weekly sessions than to rush ahead. Moving to the next phase depends on meeting your readiness signs, not on the calendar, so let your therapist guide the pace.
Do I need my therapist present for every session?
Supervision is most important early on and when you progress to new exercises. Once you are confident and your clinician agrees, you can do sessions at home, checking in regularly to review progress and technique.
