Program Overview This is a 15-week, intermediate-level rehabilitation guide for someone recovering from a knee fracture. It combines supervised strengthening, balance, and mobility work to help you rebuild function safely and steadily.
Who This Program Is For and Its Goal This program is for people past the early healing stage of a knee fracture who can bear weight and want to regain strength, balance, and confident movement. The goal is to progressively restore knee function through structured exercise while protecting the healing bone and joint. It works best when guided by your physical therapist, who can tailor each step to your body.
Before You Start Clear this program with your treating clinician first. If you have active inflammation—new swelling, heat, or sharp pain—pause and check in before continuing, since exercise during a flare can set you back. Make sure your equipment is set up safely and that someone can help you with balance work if needed.
Safety Notes Keep your spine in a neutral, comfortable position during all exercises, especially on the cable machine and balance board. Stop any activity if pain increases, and always finish with a cool-down. Never push through sharp pain, new swelling, locking, or a knee that gives way. Contact your clinician promptly if these occur, or if you notice warmth, redness, fever, or worsening symptoms.
Weekly Structure You'll do two sessions per week, about 20 minutes each, across 15 weeks. The plan moves through four phases—protection, early mobility, strengthening, and advanced function—with your clinician deciding when you're ready for the next phase based on how you're progressing.
How the 15-Week Plan Is Organized Each session is short and focused, so consistency matters more than volume. Early weeks emphasize gentle motion and muscle activation; middle weeks build strength with closed-chain and open-chain exercises plus cable-machine work; later weeks add balance-board and sport-specific challenges. Your therapist may include electrical stimulation, hands-on joint and soft-tissue work, or low-load strengthening with blood-flow restriction—all supervised—depending on your needs.
What a Typical Session Looks Like Expect a predictable rhythm: warm-up, main exercises, then cool-down. This helps your knee adapt safely and keeps each 20-minute session efficient.
Warm-Up, Main Work, Cool-Down Start with gentle motion and easy muscle-setting to wake up the knee. Main work may include squats, leg press, quad sets, and hamstring curls, plus cable-machine resistance, balance-board practice, and supervised modalities your therapist selects. Cool down with light movement and stretching to settle the knee. Your therapist adjusts specific exercises and effort to your phase and tolerance.
Tracking Progress Your therapist will record how you feel, your knee motion, swelling, and strength, along with balance and function. Standard questionnaires and strength tests help show change over time. Bring any home notes about pain or difficulty to each visit so your plan stays accurate.
How Progression Criteria Are Used You move to the next phase when you meet the goals your clinician sets—such as comfortable motion, controlled swelling, and adequate strength and balance—not simply because time has passed. Outcome measures like strength ratios, balance tests, and knee questionnaires track your trajectory and guide safe advancement.
Recovery and Self-Care Rest, elevation, and gentle movement between sessions support healing. Follow your clinician's guidance on activity and avoid adding new exercises on your own. Keep cool-downs consistent, stay hydrated, and pace yourself—steady progress beats pushing hard.
Pain Management Cautions and Red Flags Mild soreness that settles is common; sharp or rising pain is not. Avoid medications or supplements without asking your clinician. Seek prompt care for sudden severe pain, marked new swelling, inability to bear weight, fever, or a knee that locks or gives way.
