Program Overview This is a 14-week, four-days-a-week rehabilitation plan for someone healing from a knee fracture who is ready to move into intermediate-level training. Each session runs about 60 minutes and uses ankle weights, therapy putty, and clinician-guided tools like electrical muscle stimulation, continuous passive motion, water therapy, manual therapy, and blood-flow-restriction training. The plan gradually rebuilds motion, strength, and confidence in your knee under professional supervision.

Who This Program Is For and Its Goal This program suits people recovering from a knee fracture who have completed early protection and basic motion work and now want to restore full function. Your overall goal is to regain knee bending and straightening, rebuild quadriceps and hamstring strength, and return to daily activities and higher-level movement safely. Progress is measured across 14 weeks in four phases, so you move forward only when your knee shows it is ready.

Before You Start Before beginning, have your physical therapist or physician confirm you are cleared for this level of activity and review the plan with you. Make sure your equipment fits well, that you understand how to use the ankle weights and putty correctly, and that you know your personal precautions. Ask questions about anything unclear, and never push into severe pain.

Safety Notes and When to Stop Your plan lists severe pain as a contraindication, so do not exercise through sharp or severe pain. Avoid overloading the knee, keep your spine in a neutral position during exercises, and stop if pain increases. Call your clinician if you notice sudden swelling, new instability, numbness, or pain that keeps worsening. These are signs to pause and get checked before continuing.

Weekly Structure You will train four times per week for 14 weeks, with each session lasting about 60 minutes. Sessions combine clinician-led treatments and your own exercises using ankle weights and putty. The weeks are grouped into phases that move from protection, to early motion, to strengthening and higher-level function, with each phase building on the last only when you meet the readiness signs.

How the 14-Week Plan Is Organized The plan moves through phases in plain steps. Early weeks focus on protecting the healing fracture while gently restoring motion. Middle weeks add controlled motion, muscle activation, and low-impact loading. Later weeks build strength and functional control. You advance only when your pain, swelling, motion, and strength meet the goals your clinician checks, not simply because a calendar week has passed.

What a Typical Session Looks Like Each session follows a warm-up, main work, and cool-down pattern. Warm-up may include gentle motion and stimulation or water-based movement. Main work uses ankle weights and putty for strengthening plus any clinician-applied techniques. Cool-down includes gentle stretching, soft tissue work, and settling the knee, with swelling and pain checked before you finish.

Warm-Up, Main Work, and Cool-Down With Your Equipment Warm-up loosens the knee with gentle bending and straightening, possibly using continuous passive motion or water therapy early on. Main work uses ankle weights for controlled leg strengthening and putty for grip and lower-leg muscle work, alongside clinician-guided electrical stimulation, manual therapy, or blood-flow-restriction training as appropriate. Cool-down uses light stretching and soft tissue work, and you recheck pain and swelling.

Tracking Progress Your clinician tracks your pain, swelling, knee motion, and muscle strength at each phase. You will also complete standard questionnaires and physical tests, such as strength and hopping measures, at set points. These records show whether you are ready to advance and help catch problems early, so keep noting how your knee feels day to day.

How Progression Criteria and Outcome Measures Work You move to the next phase only when you meet the readiness signs for your current phase, such as controlled pain and swelling, improving knee motion, and adequate muscle activation. Your clinician uses these criteria plus outcome measures to decide when to advance. The scored questionnaires and strength and hop tests give an objective picture of recovery over the 14 weeks.

Recovery and Self-Care Between sessions, rest the knee as needed and keep swelling down with elevation and your clinician's advice. Follow your home exercise guidance, stay consistent, and avoid sudden increases in activity. Good sleep, steady pacing, and listening to your body support healing. Report any change in symptoms so your program can be adjusted.

Pain Management Cautions and Red Flags Keep pain manageable and stop if it increases during exercise. Do not push through severe pain, and avoid overloading the knee or straining your spine. Seek prompt clinician advice for worsening swelling, new giving-way, fever, calf pain, or numbness. These may signal a problem that needs review before you continue training.

Frequently asked questions

How much pain is acceptable during exercise?
Mild discomfort that settles quickly with rest is generally acceptable, but stop if pain increases or becomes severe. Always follow your clinician's guidance on what is safe for your knee.
Do I need supervision for the electrical stimulation and blood-flow-restriction training?
Yes, these tools should be set up and monitored by a trained clinician, not used on your own. Ask your therapist to show you which parts of your program you can safely do independently.
What if I miss sessions or my knee flares up?
Missing occasional sessions is usually fine, but a flare with more pain or swelling means pausing and checking with your clinician. Do not try to catch up by overloading the knee.
