Knee replacement surgery, a common and highly effective procedure, offers immense relief from chronic pain and significantly improves mobility for those suffering from severe knee issues.

However, the recovery journey is a crucial phase that requires preparation, patience, and adherence to medical advice.

Wondering what to expect during your recovery from knee replacement surgery?

Through this blog, Mykare health will guide you on all you need to know about recovery from knee replacement surgery.

Immediate Post-Surgery Period (Days 1–7)

• The first week after knee replacement surgery is marked by intensive care and initial rehabilitation. The body is in the early stages of healing, and patients typically remain in the hospital for a few days for monitoring. Pain management begins immediately after the surgery.

• Most hospitals use a combination of methods, including intravenous painkillers, oral medications, and sometimes patient-controlled analgesia (PCA) pumps. The aim is to maintain comfort while minimizing side effects. Expect some level of discomfort as the body adjusts to the new joint.

• Patients are usually encouraged to start moving their legs on the first or second day after surgery to prevent blood clots and promote circulation. Guided by a physical therapist, exercises such as ankle pumps, leg raises, and gentle knee flexion exercises are introduced.

Transition to Home (Weeks 1–4)

• Once discharged from the hospital, most patients enter the home recovery phase. During this period, the focus shifts to continuing rehabilitation, pain control, and adjusting to daily life at home.

• Swelling and discomfort are common as the knee continues to heal. Pain management may transition to oral medications such as acetaminophen or NSAIDs, and applying ice packs several times a day is highly recommended. Keeping the leg elevated whenever resting can help reduce swelling.

• Setting up a home environment that supports recovery is essential. Clear pathways, sturdy furniture for support, and safety aids like grab bars in the bathroom help minimize the risk of falls. A raised toilet seat, shower chair, and slip-resistant mats can also make daily activities safer.

• Adhering to a structured physical therapy plan is key to regaining strength and flexibility. Your physical therapist will provide exercises designed to increase the knee’s range of motion and strengthen surrounding muscles.

The First Few Months: Regaining Strength and Independence (Weeks 5–12)

• Recovery during the second and third months focuses on building strength and transitioning to greater independence. By now, patients typically notice a reduction in swelling and improved movement, though some stiffness may still occur.

• Therapists may introduce more intensive exercises, such as partial squats, step-ups, and stationary cycling, to build strength and improve balance. Patients may be encouraged to practice walking without a cane or walker and increase their activity levels gradually.

• Some common issues during this stage include muscle weakness, scar tissue formation, and occasional discomfort. Regular stretching and targeted exercises can help minimize stiffness and improve joint mobility. Additionally, some patients might find massage or warm baths beneficial for sore muscles.

• By this stage, the need for pain medication should lessen. Discuss any concerns about pain management with your doctor, especially if pain or stiffness persists longer than expected. Transitioning to non-pharmaceutical pain relief methods, such as heat therapy or acupuncture, can also be beneficial.

• Though physical recovery is a significant part of the process, emotional well-being should not be overlooked. The prolonged recovery period can lead to feelings of frustration or even depression. Connecting with friends, joining support groups, or seeking counseling can provide emotional support and help maintain a positive mindset.

Key Improvements

Increased walking distance without assistance. Ability to perform more complex daily tasks, such as light cooking or light household chores.

Long-term Recovery (3–12 Months)

• Recovery continues beyond the initial three months, with some patients taking up to a year to fully recover. During this phase, the goal is to enhance knee function, increase stamina, and return to more vigorous activities.

• By six months, many patients are able to resume most of their daily routines, including activities like driving, light exercise, and even returning to work (if their job is not physically demanding). However, high-impact sports or activities that involve sudden movements should be avoided or approached cautiously to protect the new joint.

• Routine follow-up appointments with your orthopedic surgeon are important to monitor the healing process, check for signs of implant wear, and address any concerns. Imaging tests, like X-rays, may be performed to ensure the knee joint is positioned correctly and functioning as intended.

• Maintaining a healthy diet rich in nutrients that support bone and joint health is beneficial. Foods high in calcium, vitamin D, protein, and omega-3 fatty acids can support recovery and overall well-being.

Recommended Foods

• Leafy greens, dairy products, and fortified cereals for calcium and vitamin D.

• Lean meats, fish, and legumes for protein.

• Fatty fish like salmon for omega-3s.

Staying hydrated and limiting alcohol or tobacco use is also essential, as these substances can impede the healing process.

Safe Activities

• Walking, swimming, cycling, and low-impact exercises.

• Light hiking and gentle yoga (with guidance).

Activities to Avoid

• Running, jumping, and contact sports.

• Any high-stress activities involving the knee.

Signs of Possible Complications

• Persistent swelling or redness around the knee.

• Drainage or discharge from the incision site.

• Fever or chills, indicating potential infection.

• Sudden and severe pain or stiffness, which could indicate implant issues.

If any of these symptoms arise, it’s crucial to contact your healthcare provider immediately.

Tips for a Successful Recovery

• Adhere to Your Physical Therapy Schedule: Consistent effort is essential for regaining full mobility.

• Keep Moving, but Rest Appropriately: Balance activity with adequate rest to avoid overexertion.

• Follow Medical Advice: Strictly adhere to your surgeon’s and physical therapist’s recommendations.

• Listen to Your Body: Pay attention to how your knee responds to activity and rest.

• Stay Positive: Recovery can be a slow process; maintaining a positive mindset helps keep motivation high.
