Knee Replacement: Surgery Details & Recovery

Knee replacement is a common and highly effective surgical procedure for individuals suffering from chronic knee pain, stiffness, or limited mobility due to arthritis or injury. Whether it’s a total knee replacement or the more advanced robotic knee replacement, the goal is the same to restore function, relieve pain, and improve quality of life. With proper care and rehabilitation, most patients return to normal activities within months.

This guide covers everything you need to know about knee replacement surgery, including what it involves, the pros and cons, knee replacement recovery time, and tips for post-surgery exercises.

Understanding Knee Replacement

Knee replacement also known as knee arthroplasty is a procedure where a damaged or diseased knee joint is surgically replaced with artificial components. It’s often recommended when non-surgical treatments like medications, physical therapy, and lifestyle changes fail to relieve chronic knee pain.

The most common reason for knee replacement surgery is osteoarthritis, a condition that causes cartilage wear and joint inflammation. Other causes include rheumatoid arthritis, post-traumatic arthritis, and knee deformities.
There are several types of knee replacements:

• Total Knee Replacement (TKR): Involves replacing all surfaces of the knee joint.
• Partial Knee Replacement: Only the damaged part of the joint is replaced.
• Robotic Assisted Total Knee Arthroplasty: Uses robotic technology to increase surgical precision.

What Happens During Knee Replacement Surgery?

Knee replacement surgery is typically performed under spinal or general anesthesia. The procedure involves:

• Making an incision over the knee to access the joint.
• Removing damaged cartilage and bone surfaces.
• Reshaping the joint and placing metal and plastic implants.
• Ensuring the new joint moves smoothly before closing the incision.

The entire procedure usually lasts 1–2 hours. Patients often begin moving their knee the same day or within 24 hours post-surgery, depending on their condition and the surgical approach.

Robotic knee replacement is becoming increasingly popular due to its enhanced accuracy. In Robotic Assisted Total Knee Arthroplasty, the surgeon uses a robotic system for real-time guidance, which improves implant placement and can potentially lead to faster recovery and better outcomes.

Disadvantages of Knee Replacement Surgery

While knee replacement is generally safe and effective, it’s important to understand the risks and disadvantages of knee replacement surgery before deciding to proceed:

• Infection: As with any surgery, there’s a risk of infection, especially if proper aftercare isn’t followed.
• Blood clots: Clots can develop in the legs post-surgery and may lead to serious complications if not treated.
• Implant issues: Over time, artificial joints can wear out or become loose, sometimes requiring revision surgery.
• Limited range of motion: Some patients may not regain full knee flexibility.
• Persistent pain: While rare, some individuals continue to experience discomfort even after surgery.
• Recovery time: Full recovery can take several months, and success heavily depends on commitment to rehabilitation.

It’s essential to discuss these factors with the Best Orthopedic Doctor in Bangalore to determine whether you’re a suitable candidate for the procedure.

Knee Replacement Recovery Time

Knee replacement recovery time varies from person to person but generally follows a pattern:

• First few days: Hospital stay of 1–3 days. Patients start walking with assistance and begin gentle movements.
• Weeks 1–6: Gradual increase in mobility. Physical therapy is crucial during this phase to regain strength and flexibility.
• Months 2–3: Many patients resume light activities, including walking, climbing stairs, and light housework.
• By 6 months: Most people return to a normal routine, although high-impact activities like running should be avoided.
• Full recovery: Usually achieved within 6–12 months, depending on age, health, and commitment to rehabilitation.

Following your surgeon’s advice and sticking to a rehabilitation plan are key to a successful outcome.

Knee Replacement Exercises

After surgery, knee replacement exercises are vital to ensure a strong, flexible, and functional joint. Here are some commonly recommended ones:

• Ankle pumps – Promote blood flow and prevent clots.
• Quad sets – Strengthen thigh muscles.
• Straight leg raises – Improve leg strength without bending the knee.
• Heel slides – Enhance knee flexibility and bending range.
• Stationary cycling – Great for joint mobility once initial healing has occurred.

Patients usually work with a physical therapist for the first few months. Performing these exercises regularly speeds up recovery and reduces the risk of complications.

Robotic Knee Replacement: A Technological Leap

Robotic knee replacement has gained popularity for its precision and customization. In Robotic Assisted Total Knee Arthroplasty, the surgeon uses a robotic arm to guide the placement of the implant based on a detailed 3D model of the patient’s knee.

Benefits include:

• Increased accuracy in bone removal and implant alignment.
• Less soft tissue damage, leading to quicker recovery.
• Improved joint function and more natural knee movement post-surgery.
• Fewer complications and better long-term outcomes.

If you’re considering knee surgery, ask your orthopedic specialist if you’re a candidate for robotic-assisted surgery.

When to Consider Knee Replacement

Surgery isn’t the first step. However, knee replacement may be recommended if you experience:

• Severe knee pain that limits daily activities.
• Chronic inflammation and swelling that doesn’t improve with rest or medication.
• Knee stiffness that prevents normal bending and straightening.
• No relief from other treatments like physical therapy or injections.

Discussing symptoms with the Best Orthopedic Doctor in Bangalore can help determine if surgery is the right next step.

Frequently Asked Questions

What is the average knee replacement recovery time?

Most people recover within 6 to 12 weeks for basic daily activities, but full recovery—including regaining full strength and flexibility—can take up to 6 months or more, depending on age, health, and rehab consistency.

Are there any disadvantages of knee replacement surgery?

Yes. Some potential disadvantages include infection, blood clots, limited range of motion, and in rare cases, persistent pain. Implants may also wear out over time, sometimes requiring revision surgery. However, most patients experience significant pain relief and improved mobility.

What is robotic knee replacement and how is it different?

Robotic knee replacement uses a robotic system to assist the surgeon during the procedure, allowing for more precise implant positioning and less soft tissue damage. This often results in faster recovery and better long-term joint function compared to traditional surgery.
