Intermediate Knee Post-Fracture Rehabilitation Program (15 Weeks) This is a 15-week, therapist-guided program for people recovering from a knee fracture who are ready to move from early protection into more active strengthening and balance work. It combines progressive exercise, hands-on therapy, muscle stimulation, and balance training, with your knee brace, hand exerciser, and dumbbells. The plan runs three sessions per week at about 60 minutes each.
Who This Program Is For and Its Goal This program is for adults healing from a knee fracture who have orthopedic clearance to begin intermediate rehabilitation. Its goal is to restore knee motion, rebuild thigh and hip strength, improve balance and confidence on the leg, and help you return to daily activities and higher-level movement safely. Your clinician will tailor every exercise to your stage of healing and adjust the pace to how your knee responds.
Before You Start Start only after your orthopedic clinician confirms your fracture is stable enough for this level of activity and that your brace and weight-bearing instructions are current. Your physical therapist should assess your knee motion, swelling, strength, and walking status before you begin, and review your brace settings. Never change brace use or weight-bearing on your own—follow your care team's directions at each visit.
Safety Notes and When to Stop Do not start or continue if you have an active infection, an unstable fracture fixation, signs of compartment syndrome, or severe osteoporosis, as these require medical review first. Always warm up before activity and cool down afterward. Stop and call your clinician right away if you have sudden severe pain, new or worsening swelling, fever, calf pain or tightness, numbness, or a knee that feels unstable or gives way.
Weekly Structure Plan for three sessions each week, roughly 60 minutes each, across 15 weeks. Your brace is worn as directed, the hand exerciser supports grip and upper-body work, and dumbbells add resistance as your strength allows. The program moves through early protection and pain control, then early motion, then progressive strengthening, balance, and return-to-activity work as you meet your milestones.
How the 15-Week Plan Is Organized The plan is divided into phases that build on each other. Early weeks focus on protecting the healing bone, controlling pain and swelling, and gently restoring motion. Middle weeks add active movement and strengthening. Later weeks emphasize strength, balance, and proprioception. You advance when you meet your clinician's milestones, not simply because a certain number of weeks has passed, so progress at your own safe pace.
What a Typical Session Looks Like Each session follows a warm-up, main work, and cool-down pattern. Your therapist may include hands-on joint and kneecap mobilization and, where appropriate, muscle stimulation to help your thigh muscle activate. Balance and proprioception work, such as single-leg stance and wobble board tasks, is added when you are ready. Aquatic therapy may be used early when indicated to support weight-bearing and motion.
Warm-Up, Main Work, and Cool-Down Begin with a gentle warm-up to prepare the knee and leg. The main work includes therapeutic exercise such as open-chain knee extension and flexion, closed-chain leg press, and squat progressions, using dumbbells for added resistance as appropriate. Balance and proprioception drills come next. Finish with a cool-down to settle the knee. Your therapist sets the exact exercises, repetitions, and resistance based on your assessment.
Tracking Progress Your therapist will record your pain, swelling, knee motion, strength, and walking status at intervals, along with your brace and weight-bearing stage. Standard outcome measures may include the KOOS, IKDC, and Lysholm questionnaires, the Single Leg Hop Test, the Timed Up and Go, and a quadriceps strength index. These track how your function changes over the 15 weeks and help guide your program.
How Progression Criteria Are Used You move between phases when you meet the milestones your clinician sets—such as controlled pain, reduced swelling, improved knee extension, adequate motion, and safe weight-bearing—rather than by calendar alone. Outcome measures add an objective picture of your strength and function over time. If a milestone is not yet met, your therapist adjusts the exercise rather than pushing ahead unsafely.
Recovery and Self-Care Rest, elevate, and ice the knee as advised after sessions, especially if it feels swollen or sore. Keep using your brace and assistive device exactly as instructed, and stay consistent with your home exercises between visits. Eat well, stay hydrated, and protect sleep to support healing. Report changes in pain, swelling, or function to your therapist so your plan can be adjusted.
Pain Management Cautions and Red Flags Some mild soreness with activity can be expected, but sharp or escalating pain, new swelling, warmth, redness, fever, calf pain or tightness, chest pain, or shortness of breath are reasons to stop and contact your clinician promptly. Do not push through pain or change your brace, weight-bearing, or medications on your own. Follow your care team's guidance for pain relief and activity limits.
