Program Overview This is a 22-week, intermediate-level rehabilitation guide for someone recovering from a knee fracture that involved the surrounding ligaments. It uses simple equipment—a suspension trainer and a balance board—across two short sessions each week. The plan follows a stepwise path from protecting the healing knee toward building strength and balance, with clinician checkpoints along the way.

Who This Program Is For and Its Goal This program suits people whose fracture is healing and who have been cleared to begin guided exercise, including those with involvement of the knee's stabilizing ligaments. The goal is to gradually restore knee movement, muscle control, strength, and balance so you can return to everyday activities and, over time, more demanding ones. Progress depends on meeting checkpoints, not just the calendar, so your pace may differ from someone else's.

Before You Start Please have your clinician confirm you are ready for this level of activity. Do not begin if you have severe pain, any signs of infection, or knee movement limits that haven't been assessed. Your therapist should also review the ligament and meniscus tests noted in your plan. This guide supports—but does not replace—supervised care, especially in the early weeks.

Safety Notes and When to Stop Exercise should feel challenging but not sharp or escalating. Stop and call your clinician if you notice severe or worsening pain, new swelling, warmth, redness, fever, a knee that gives way, or pain that lingers well after sessions. Keep your spine in a comfortable neutral position during exercises, and avoid overloading the knee. Never push through infection-type symptoms; these need prompt medical review.

Weekly Structure You will do two sessions per week, each about 20 minutes, for 22 weeks. Each session uses the suspension trainer and balance board as your main tools. Plan your sessions on non-consecutive days so your knee has recovery time between them.

How the 22-Week Plan Is Organized The plan moves through four broad phases: protection and pain control, early motion, controlled motion, and strengthening. Early on, the focus is gentle muscle activation and quieting pain; later it shifts toward fuller movement, weight-bearing, and balance work. Your therapist may add supportive treatments like muscle stimulation, a motion machine, water therapy, or ultrasound as appropriate. Each phase has checkpoints you meet before advancing.

What a Typical Session Looks Like Expect each session to follow a steady rhythm: warm up, do the main exercises, then cool down. The suspension trainer supports controlled movements, and the balance board challenges your stability when you're ready. Keep movements smooth and within a comfortable range.

Warm-Up, Main Work, Cool-Down Start with gentle movement to warm the knee, such as easy range-of-motion and light activation. The main work uses the suspension trainer for supported strengthening and the balance board for stability—your therapist adjusts difficulty as you progress. Cool down with calm stretching and easy motion. Throughout, keep your spine neutral and avoid sudden overload on the knee.

Tracking Progress Your therapist will record how you're doing using standard knee questionnaires, range-of-motion measurements, strength testing, and a single-leg hop test for symmetry. These give an objective picture of recovery and help catch problems early. Between visits, note your pain levels, swelling, and how exercises felt so you can share patterns at your next session.

How Progression Criteria and Outcome Measures Work Together You move to the next phase by meeting specific checkpoints—for example, showing muscle activation, reaching certain pain-free movement, or demonstrating strength and balance—rather than by time alone. Outcome measures such as the Lysholm, IKDC, KOOS, and strength and hop tests confirm that gains are real and guide adjustments. If a checkpoint isn't met, your therapist may keep you in the current phase longer.

Recovery and Self-Care Rest between sessions, keep swelling in check, and protect sleep and general activity. Follow your clinician's advice on pain relief and any supportive treatments; this guide does not prescribe medicines or dosages. Gentle activity and pacing help recovery, but respect signals from your knee rather than pushing through discomfort.

Pain Management Cautions and Red Flags Avoid overloading: back off if pain rises during or after exercise. Seek prompt care for severe pain, fever, spreading redness or warmth, new significant swelling, or a knee that feels unstable or locks. These could signal a problem that needs assessment. When in doubt, pause the program and contact your clinician rather than continuing.

Recovery phases

Frequently asked questions

How much pain is acceptable during exercise?
Mild, manageable discomfort that settles quickly is generally acceptable, but sharp or rising pain is a signal to ease off. Check with your clinician if you're unsure whether what you feel is safe.
Can I move to the next phase sooner if I feel good?
Advancing depends on meeting the checkpoints, not just feeling ready. Your therapist confirms progress with testing so you don't move ahead before the knee is prepared.
What if I miss sessions or have a setback?
Missing a session isn't a crisis; resume when you can and tell your therapist. If pain or swelling flares, pause and get guidance before pushing forward again.
