Program Overview This is a 23-week, twice-weekly, 30-minute intermediate rehabilitation program for adults recovering from a knee fracture. It combines progressive strengthening, water-based exercise, electrical stimulation for the thigh muscle, balance work, and safe low-load strengthening. Sessions use a barbell, a knee brace, and therapy putty. The plan moves in gentle phases, guided by your clinician, so you build strength, motion, and confidence at a pace your knee can tolerate.

Who This Program Is For and Its Goal This program suits people past the early healing stage of a knee fracture who have some weight-bearing clearance and want to rebuild thigh and hip strength, knee motion, and balance. The goal is to restore comfortable daily function and steady, measurable strength gains without overloading the healing bone and joint. Your clinician confirms you meet the starting criteria before you begin and oversees your progress throughout.

Before You Start Do not begin without your clinician's approval. Your therapist should check swelling, knee motion, ligament stability, and bone healing, and fit your knee brace properly. Confirm your weight-bearing status, review any wound care, and clarify safe barbell loads. Ask how to use the therapy putty and electrical stimulation device correctly. Ensure you can warm up safely and that your home setup allows clear space and stable support.

Safety Notes and When to Stop Do not exercise if you have severe pain, signs of infection (increasing redness, warmth, swelling, fever), possible blood clot symptoms (calf pain, swelling, chest pain, breathlessness), or a wound that is opening. Stop immediately and call your clinician if pain sharply increases, the knee gives way, swelling rises quickly, or you feel faint. Maintain a neutral spine, avoid overloading, and always warm up first. Skip blood flow restriction training if you have vascular or clotting concerns unless specifically cleared.

Weekly Structure You train twice a week for 30 minutes across 23 weeks. The plan moves through phases — protection and acute care, early mobility, protected strengthening, and progressive loading — with later weeks building on these gains. Each phase has readiness checkpoints, and your clinician decides when you advance. Shorter, consistent sessions beat long, tiring ones, so keep the pace steady and leave time to cool down.

How the 23-Week Plan Is Organized Sessions total 30 minutes, twice weekly, using the barbell, knee brace, and therapy putty. Early weeks emphasize swelling control, gentle motion, water therapy, and electrical stimulation to wake up the thigh muscle. Middle weeks add protected strengthening and balance. Later weeks progress to heavier loading, balance challenges, and optional low-load strengthening with blood flow restriction. Your clinician adjusts the pace based on how your knee responds and on the phase checkpoints.

What a Typical Session Looks Like Expect a short warm-up, a main block of strengthening and balance work, and a cool-down. Your therapist sets the details. The structure stays consistent so you can focus on smooth, controlled movement and steady breathing. Bring your brace to every session and wear supportive footwear. Report how your knee feels afterward, since that feedback guides the next session.

Warm-Up, Main Work, and Cool-Down Warm up with gentle knee bending, easy walking, and light putty squeezing to prepare muscles. The main work includes progressive barbell exercises for thigh, hamstring, and hip muscles, balance drills like single-leg stance or wobble-board work, and electrical stimulation for the thigh as directed. Cool down with gentle stretching, slow walking, and easy range-of-motion movements. Keep your spine neutral and avoid overloading, especially on the barbell work.

Tracking Progress Your clinician records swelling, knee motion, pain, and strength at each phase checkpoint, and may use outcome measures like the Lysholm, IKDC, KOOS, Tegner scale, single-leg hop distance, and quadriceps limb symmetry. These show whether you are ready to progress. Track your own symptoms and session notes between visits so adjustments can be made early and safely.

How Progression Criteria Are Used Phase checkpoints — such as controlled swelling, specific knee motion ranges, muscle activation, ligament stability, and pain-free loading — guide when you advance. These are clinical judgments, not fixed cutoffs, so your therapist interprets them alongside your outcome scores and how you feel. Meeting a checkpoint doesn't automatically mean moving on; your clinician confirms readiness. Outcome measures help compare your injured and healthy legs over time.

Recovery and Self-Care Rest between sessions, elevate the knee if it swells, and follow your brace and wound-care instructions. Stay active within comfort, keep hydrated, and prioritize sleep, which supports healing. Use ice or other comfort measures only as your clinician advises. Report changes promptly rather than pushing through. Consistency with your home exercises, when prescribed, matters as much as the supervised sessions.

Pain Management Cautions and Red Flags Mild, temporary soreness after exercise can be normal, but sharp or escalating pain is not. Do not mask worsening pain to complete a session. Seek urgent care for chest pain, breathlessness, calf swelling, fever, spreading redness, or a wound that opens. Otherwise, contact your clinician if swelling persists, the knee feels unstable, or you cannot tolerate your prescribed activity.

Frequently asked questions

How much soreness is normal after a session?
Mild soreness that settles within a day or so is common, but sharp or lasting pain is a signal to ease off and tell your clinician. Your therapist will help you find a safe level of effort.
Can I skip the knee brace during exercise?
Only if your clinician says it is safe, since the brace protects healing tissue during loading. Ask before changing how or when you wear it.
Why include electrical stimulation if I can already move my knee?
Electrical stimulation helps wake up and strengthen the thigh muscle, especially early on, which supports better movement and loading. Your therapist sets how it is used alongside your exercises.
