Program Overview This is a 16-week, intermediate-level rehabilitation guide for someone recovering from a knee fracture. It uses progressive resistance training, balance work, electrical stimulation, aquatic therapy, and a gradual plyometric program to rebuild strength, mobility, and confidence in your knee.
Who This Program Is For and Its Goal This program is for people whose knee fracture is healing and who have been cleared to move into intermediate rehabilitation. The goal is to restore knee motion, rebuild quadriceps and hamstring strength, improve balance on unstable surfaces, and safely return to more demanding activity like hopping and jumping, all under clinician supervision.
Before You Start Before beginning, have your clinician confirm your fracture is stable, your swelling is under control, and you are safe to bear weight. Warm up before every session, stop if pain increases, and cool down afterward. Use your knee brace as directed by your care team.
Safety Notes and When to Stop Do not exercise if you have signs of acute inflammation (new warmth, swelling, or sharp pain) or any infection (fever, redness, or drainage near the knee). Stop and call your clinician if pain worsens during or after exercise, swelling increases, your knee gives way, or you develop new numbness or fever.
Weekly Structure You will do five sessions per week, about 20 minutes each, for 16 weeks. Early weeks focus on protection and gentle motion; middle weeks build mobility and strength; later weeks add balance and controlled plyometrics. Equipment includes a balance board, barbell, dip station, suspension trainer, and brace.
How the 16-Week Plan Is Organized The plan moves through phases: early protection, early mobility, then progressive strengthening and balance, finishing with plyometric progression. Your clinician advances you between phases based on meeting specific movement and strength checks rather than the calendar alone, so your pace may vary. Water therapy can support early weight bearing.
What a Typical Session Looks Like Each 20-minute session follows a warm-up, main work, and cool-down pattern. Warm up with easy motion and gentle muscle activation. Main work uses closed-chain resistance (squats, step work, suspension-trainer holds), balance-board work, and electrical stimulation as directed. Cool down with gentle stretching and easy movement.
Warm-Up, Main Work, and Cool-Down Pattern Warm up with relaxed cycling or light knee-bending and thigh squeezes. Main work alternates strength exercises such as closed-chain squats or dip-station-supported movements, balance-board challenges, and suspension-trainer control drills, with quadriceps stimulation if prescribed. Cool down with slow stretches and easy walking to settle the knee.
Tracking Progress Your clinician will track swelling, knee range of motion, strength, and balance at intervals. You will also complete questionnaires like the IKDC, KOOS, Lysholm scale, and patellofemoral pain scale, plus strength and hop testing, to measure change over time and guide decisions.
How Progression Criteria Are Used You move to the next phase when you meet the movement and strength checks for your current phase, such as reaching a range-of-motion target, having minimal swelling, and showing adequate muscle control. Outcome measures add the bigger picture of how your knee feels and functions, so progression is based on both.
Recovery and Self-Care Rest, ice, and elevation as advised help manage swelling after sessions. Keep to your brace and weight-bearing instructions, stay active within your limits, and prioritize sleep and good nutrition. Report any change in symptoms to your clinician rather than pushing through.
Pain Management Cautions and Red Flags Mild soreness that settles with rest is common, but stop if pain steadily increases, swelling rises, or the knee feels unstable. Do not take new medications without advice from your care team. Seek prompt care for fever, spreading redness, calf pain, or sudden loss of function.
