Knee Replacement Surgery

1. What is Knee Replacement Surgery?

Knee replacement, also called knee arthroplasty, is a surgical procedure in which damaged joint surfaces are replaced with specially designed artificial components. It is commonly performed when severe knee damage causes persistent pain and significant difficulty with movement.

2. When is Knee Replacement Recommended?

Knee replacement may be recommended for patients with:

• Severe osteoarthritis
• Rheumatoid or inflammatory arthritis
• Significant knee joint damage
• Persistent pain despite non-surgical treatment
• Difficulty walking or performing daily activities
• Severe stiffness or deformity

The decision is based on symptoms, examination findings, imaging and response to conservative treatment.

3. What Symptoms May Indicate the Need for Surgery?

Patients may experience:

• Persistent or severe knee pain
• Difficulty walking or climbing stairs
• Knee stiffness
• Swelling
• Reduced range of movement
• Knee deformity
• Pain affecting sleep or daily activities

4. What Does the Procedure Involve?

The general treatment process includes:

Orthopaedic evaluation → X-rays and preoperative assessment → Surgical planning → Anaesthesia → Removal of damaged joint surfaces → Implant placement → Postoperative monitoring → Physiotherapy and rehabilitation

The artificial components are designed to restore smooth joint movement and stability.

5. What Types of Knee Replacement Are Available?

Depending on the extent of joint damage, the procedure may include:

• Total Knee Replacement (TKR/TKA) – replacement of the main damaged joint surfaces
• Partial Knee Replacement – replacement of only the affected compartment in selected patients
• Revision Knee Replacement – replacement or correction of a previous knee implant

The orthopaedic surgeon recommends the most appropriate procedure after evaluation.

6. How Long Does Surgery and Recovery Take?

Knee replacement surgery commonly takes approximately 1–3 hours.

Typical recovery may include:

• Hospital stay: approximately 3–7 days
• Early walking and physiotherapy: usually begins soon after surgery
• Initial recovery: several weeks
• Continued improvement: may continue for several months

Recovery depends on age, fitness, the condition of the knee and adherence to rehabilitation.

7. What Are the Expected Benefits and Outcomes?

Successful knee replacement may help:

• Significantly reduce knee pain
• Improve walking and mobility
• Improve joint stability
• Make daily activities easier
• Improve quality of life

Implant longevity varies depending on patient factors, activity level and implant type.

8. What Are the Risks or Considerations?

Potential risks include:

• Infection
• Blood clots
• Bleeding
• Persistent pain or stiffness
• Implant loosening or wear over time
• Nerve or blood-vessel injury
• Need for revision surgery in the future

A structured rehabilitation programme is important for recovery.
