What is Knee Replacement (Total Knee Arthroplasty)? When is it Necessary?

29/03/2026

Knee pain is one of the most common conditions that significantly reduces quality of life, especially with advancing age. Simple daily activities such as walking, climbing stairs, or even standing up can become difficult. In such cases, total knee replacement is one of the most effective and reliable treatment options.

🧠 What is Knee Replacement?

Total knee replacement is a surgical procedure in which the damaged surfaces of the knee joint are replaced with artificial components.

  • Worn-out cartilage and damaged bone surfaces are removed
  • Artificial components made of metal and polyethylene are implanted
  • The joint is restored to allow smooth and pain-free movement

👉 The primary goal is to relieve pain and restore function

⚠️ When is Knee Replacement Necessary?

Knee replacement is typically recommended in advanced knee osteoarthritis when other treatments are no longer effective.

🔴 Common reasons include:

  • Severe osteoarthritis (degenerative joint disease)
  • Rheumatic diseases
  • Post-traumatic joint damage
  • Long-standing meniscus or ligament injuries

🚨 When should surgery be considered?

Surgery may be recommended if you experience:

✔ Persistent and severe knee pain
✔ Night pain affecting sleep
✔ Significant limitation in walking distance
✔ Difficulty climbing stairs
✔ No improvement with medications or physical therapy

👉 Important: The decision is based on your symptoms, not just X-rays.

🏥 How is the Surgery Performed?

  • The procedure takes approximately 1–2 hours
  • Performed under spinal or general anesthesia
  • Damaged joint surfaces are removed
  • The prosthesis is placed with precise alignment

👉 In selected cases, robot-assisted surgery can improve precision and outcomes.

⏳ Recovery After Surgery

  • Day 1: Standing and walking begin
  • Day 2–3: Discharge from hospital
  • 2–4 weeks: Return to daily activities
  • 6 weeks: Improved mobility
  • 3 months: Significant recovery

👉 The key to success is structured rehabilitation and physiotherapy

🦵 How Long Does a Knee Prosthesis Last?

Modern implants can last:

👉 15–20 years or longer

Longevity depends on:

  • Surgical technique
  • Patient factors
  • Activity level

⚠️ Is Knee Replacement Safe?

Like any surgery, there are some risks:

  • Infection
  • Blood clots
  • Implant loosening

👉 However, with modern techniques, these risks are low and well controlled

✔ Medications
✔ Physical therapy
✔ Injections (PRP, hyaluronic acid)
