Total Knee Replacement Rehab Protocol & Recovery Timeline

This protocol outlines The Stone Clinic's rehabilitation framework after robotic-assisted, cementless total knee replacement using the Stryker MAKO Robotic-Arm Assisted Orthopaedic System. The recovery estimates on this page are specific to Kevin R. Stone, MD's robotic-assisted total knee replacement program; recovery times may be longer with traditional forms of knee replacement.

Total knee replacement recovery begins right away at The Stone Clinic. Early rehab focuses on walking, controlling swelling, regaining full extension, restoring motion, and rebuilding strength so patients can return to the activities they love.

Robotic total knee replacement recovery timeline at a glance

The protocol below is organized by recovery phase, from early protection and range of motion through endurance, strength, and return-to-activity training.

• Weeks 1-2: Max protection phase
• Weeks 2-4: Moderate protection phase
• Weeks 4-12: Endurance phase
• Weeks 12-16: Strength phase

These timelines are approximate. Progression through rehab depends on the patient’s clinical presentation and meeting the goals and criteria for each phase.

Total knee replacement recovery time: what to expect after surgery

Dr. Stone's team explains what patients can expect in the first days and weeks after knee replacement surgery, including early walking, swelling control, extension, and range-of-motion goals.

Important guidelines before starting total knee replacement rehab

The following guidelines apply to The Stone Clinic’s total knee replacement rehabilitation protocol.

• Patients are weight-bearing as tolerated with use of crutches, walker, or cane for approximately 2 weeks.
• Early emphasis is on regaining full extension.
• Avoid direct palpation of the scar for 4 weeks.
• All timelines and recommendations are subject to change, as each individual case is different.

Total knee replacement recovery weeks 1-2: Max protection phase

The first two weeks focus on walking, swelling control, regaining full extension, early motion, and beginning the return to normal gait.

Weight-bearing

• Weight-bearing as tolerated with crutches.
• Slowly wean from crutches based on symptoms and gait quality.

Range of motion

• 0-90 degrees.

Manual therapy

• Patellofemoral mobilization.
• Soft tissue mobilization to lower limb musculature.
• Avoid direct palpation of surgical portals.

Recommended exercises

• Knee hangs.
• Quad sets.
• Gluteal sets.
• Terminal knee extension.
• Multi-directional straight leg raises.

Goals for progression

• Minimal pain.
• Minimal swelling.
• Wean from crutches.
• Normal gait.
• Normal extension and 100 degrees of flexion compared to the other knee.
• Able to tolerate stationary bike.

Total knee replacement rehab weeks 2-4: Moderate protection phase

This phase continues the transition toward full weight-bearing, improved range of motion, cycling, gait training, and controlled strengthening.

Weight-bearing

• Full weight-bearing as tolerated.

Range of motion

• 0-100/120 degrees.

Manual therapy

• Patellofemoral mobilization.
• Soft tissue mobilization to lower limb musculature.
• Avoid direct palpation of surgical portals.

Recommended exercises

• Knee range-of-motion exercises.
• Calf raises.
• Straight leg raises.
• Bodyweight mini squats.
• Step-ups.
• Stationary cycling program as range of motion allows.
• Gait training.

Total knee replacement recovery weeks 4-12: Endurance phase

The endurance phase builds walking tolerance, functional strength, and controlled movement while continuing to restore range of motion.

Weight-bearing

• Full weight-bearing.

Range of motion

• Unrestricted as symptoms allow.
• Begin active range of motion as tolerated, less than 120 degrees.

Manual therapy

• Patellofemoral mobilization.
• Soft tissue mobilization to lower limb musculature.
• Initiate gentle scar mobilization if portals are closed.

Recommended exercises

• Progress to higher-volume, lower-load functional exercises, including double-leg and single-leg squats, step-ups, and step-downs.

Goals for progression

• Passive flexion range of motion 130+ degrees.
• Able to squat to 90 degrees without pain.
• Able to ascend and descend stairs pain-free.
• Pass Stone Fitness Test I at approximately 12 weeks.

Total knee replacement rehab weeks 12-16: Strength phase

The strength phase increases load and prepares the patient for longer walking, light hiking, and the activities or sports they want to return to.

Weight-bearing

• Full weight-bearing as tolerated.
• Slowly increase tolerance to longer walking and light hiking distances.

Range of motion

• Unrestricted as symptoms allow.

Manual therapy

• Continue soft tissue and scar mobilization as needed.
• Manual therapy may be used as a means of recovery.

Recommended exercises

• Higher-load, lower-volume strength training.
• Progressive closed-chain resistance training for all lower extremity muscle groups.
• Activity and sport-specific power and agility exercises.

Goals for progression

• Full range of motion.
• Independent in-home exercise program.
• Able to participate in desired sport or activity unrestricted.
• Patient-specific goal.

Why robotic-assisted total knee replacement recovery may be faster

This recovery pathway is tied to Dr. Stone’s robotic-assisted total knee replacement program. Using the Stryker MAKO system, Dr. Stone creates a personalized surgical plan and uses a computerized 3-D model of the patient’s knee to guide highly accurate implant placement.

The procedure is designed to support faster recovery and higher-level activity through robotic-driven accuracy, an outpatient surgery pathway, immediate physical therapy, and whole-body fitness training. At The Stone Clinic, the goal is to relieve pain, restore motion, and help patients return to the activities they love—often including running, skiing, hiking, swimming, and tennis.
