An artificial implant is used to replace a sick, worn-out, or injured knee joint in knee replacement surgery, also known as knee arthroplasty. It is frequently done to treat severe cases of arthritis or injuries in order to reduce discomfort and restore function.
When Does Someone Need a Knee Replacement? (Signs)
When conservative treatments such as medicines, injections, and physical therapy fail, surgery may be considered. Symptoms include:
- Excruciating knee pain, even at night or even at rest.
- Reduced mobility and stiffness (difficulty walking, climbing stairs).
- Prolonged edema and inflammation.
- Knee deformity (look of knock-kneed or bow-legged).
- Reaction to steroids, NSAIDs, or viscosupplementation was unsuccessful.
Typical Conditions That Lead to Knee Replacement:
- The most prevalent cause of wear-and-tear arthritis is osteoarthritis.
- Rheumatoid arthritis (damage to autoimmune joints).
- post-traumatic arthritis, which develops following ligament damage or fractures.
- Avascular necrosis: bone death brought on by inadequate blood flow.
Different Knee Replacement Surgery Types
1. TKR, or total knee replacement
- The knee joint is completely replaced with metal and plastic components.
- Most prevalent kind of advanced arthritis.
2. Unicompartmental partial knee replacement
- The knee's medial/lateral side is the only injured portion that is replaced.
- Faster recuperation, but only for small-scale injuries.
3. Kneecap replacement (patellofemoral arthroplasty)
- The only parts replaced are the groove and kneecap.
- Used when the front of the knee is the only area affected by arthritis.
4. Knee replacement revision
- If an implant fails (due to wear, infection, or loosening), this is done.
