How Long Does It Take to Recover Full Range of Motion After Total Knee Replacement?

Achieving full range of motion post-knee replacement varies among individuals and typically occurs within several weeks to months with diligent rehabilitation efforts. Adherence to prescribed exercises and physical therapy sessions greatly influences the recovery timeline.

Personal Experience

My trail running resumed after six weeks on my right knee, but getting my left knee to the point of running again took two months. Everyone's recovery is different, influenced by factors such as physical condition and post-surgery exercises.

After my total knee replacement (TKR), my range of motion differed in each leg. My right knee bent at 65 degrees, while my left knee bent at 75 degrees. The hardware and scar tissue might have limited my full range of motion. Over time, I realized that these were the movements my knees would accommodate.

Factors Affecting Recovery

It's important to note that recovery times can vary substantially. Some people may attend their first follow-up appointment in two or three weeks, while for others, it takes a few months. Obese and overweight individuals often take longer to recover. My wife, who had a thigh bone replacement, started walking around the house after just ten days. Online, some individuals reported being able to visit the gym after three weeks.

My Personal Timeline

By the time I left the hospital after three days post-surgery, I achieved a flexion of 101° and an extension of 3°. After about a month and a half of physiotherapy, my knee could bend 117°, which was good because the prosthetic allows just 120° of flexion. My physiotherapist provided a lot of encouragement, advice, and understanding, which greatly helped my recovery.

Strategies and Tips for Recovery

It's crucial to address the pain associated with your knee replacement because it can limit your mobility and scar tissue formation, which can hinder your range of motion. Use painkillers, especially before and after physiotherapy, to manage pain and help you regain your strength and mobility. Don't be afraid of the pain; using painkillers can allow you to exercise more effectively.

Avoiding the formation of scar tissue is vital. Exercising helps prevent atrophy and stiffness, which can restrict your mobility. Post-surgery, there is a lot of swelling that makes it harder to regain flexion and extension early on. Ice packs can be helpful in reducing swelling, and using them a few times a day is recommended. Listen to your body but don't give up on your recovery. Everyone heals at a different rate, and recovery experiences can vary.

Finally, it's essential to strike a balance between pushing yourself and pushing too hard. Progress slowly and sensibly, and eventually, you will reach your desired level of recovery. Don't judge yourself or compare your recovery to others, as everyone heals at a different pace and experiences pain differently.
