Intermediate Knee Post-Fracture Rehabilitation — Program Overview

This 18-week, intermediate-level program is for people recovering from a knee fracture who have completed initial healing and early rehab, and whose surgeon or clinician has cleared them to progress. It is designed for those ready to build strength, balance, and confidence in the knee. The goal is to steadily restore knee function, quadriceps strength, and safe movement through progressive resistance, balance training, and other supervised therapies, using a rower and balance pad alongside clinic-based modalities.

Before You Start

Only begin this program with your clinician's approval. This plan is not appropriate if you have unstable fracture fixation, an open or healing wound, severe osteoporosis, or a very recent fracture—your care team will confirm these are resolved or safe to work around. Stop and call your clinician if you feel sharp or worsening pain, notice new swelling, have a knee that gives way or locks, feel numbness, or develop redness or drainage at an incision. Avoid overloading the knee and keep your spine in a neutral position during exercise.

Weekly Structure

The plan runs 18 weeks at five sessions per week, about 30 minutes each, using a rower and balance pad plus clinic equipment and modalities as directed. Early weeks focus on protection, pain control, and gentle quadriceps activation. Middle weeks build mobility, strength, and balance. Later weeks emphasize progressive resistance, proprioception, and function. Your clinician decides when you move to the next phase based on the progression criteria and your response.

What a Typical Session Looks Like

Sessions follow a warm-up, main work, and cool-down pattern. Warm up briefly with gentle range-of-motion and easy rower work as tolerated. The main work may include progressive resistance exercise, quadriceps strengthening, balance and proprioception drills on the balance pad, and modalities such as electrical stimulation, blood flow restriction, or aquatic therapy as your clinician prescribes. Cool down with light movement and stretching. Keep the spine neutral and avoid overloading the knee throughout.

Tracking Progress

Your clinician uses the phased progression criteria—such as quadriceps activation, knee range of motion, swelling, and strength—to decide when you advance. Outcome measures like the Lysholm, IKDC, KOOS, Single Leg Hop Test, Quadriceps Index, and patellofemoral pain scale are collected periodically to track your recovery objectively. These guide adjustments; they are not targets you need to hit alone, and your clinician interprets the results with you.

Recovery and Self-Care

Expect some soreness after activity, but avoid pushing through sharp or escalating pain. Follow your clinician's guidance on rest, swelling control, and activity pacing. Watch for red flags such as sudden increased swelling, a knee that gives way, locking, fever, or wound changes, and report these promptly. Keep movements controlled, maintain a neutral spine, and avoid overloading the healing knee between sessions.

Frequently asked questions

Can I skip sessions if my knee feels fine?

Try to stay consistent, but talk to your clinician before skipping or doubling up, since steady pacing supports healing. Feeling good is encouraging, but progression should still follow your clinician's plan.

What if the rower or balance pad causes discomfort?

Ease off or stop that activity and let your clinician know so they can adjust the exercise. Discomfort that builds or persists is a signal to modify, not push through.

How do I know when I'm ready for the next phase?

Your clinician confirms readiness using the progression criteria, such as range of motion, strength, and swelling, rather than time alone. Keep attending reviews so these checkpoints can be measured safely.
