The process known as hip replacement surgery, or total hip arthroplasty, involves replacing a diseased or injured hip joint with an artificial implant. It is frequently done for people with severe arthritis or injuries to reduce pain and regain movement.
Signs That Point to the Need for Hip Replacement
When conservative therapies (medication, physical therapy, injections) are unsuccessful, hip replacement is recommended. Symptoms include:
- Chronic hip discomfort that becomes worse when you move and doesn't go away while you're at rest.
- Walking, bending, and ascending stairs might be challenging due to stiffness and decreased range of motion.
- Joint deformity (visible changes are a sign of advanced arthritis).
- Nonsurgical treatments that didn't work (painkillers, therapy no longer assist).
Common Disorders That Cause Hip Replacement:
- The most prevalent cause of wear-and-tear arthritis is osteoarthritis.
- Rheumatoid arthritis (damage to autoimmune joints).
- Avascular necrosis, or the hip bone's loss of blood flow.
- Hip fractures (due to osteoporosis or trauma).
- Congenital hip conditions, such as hip dysplasia.
Types of Hip Replacement Surgery
1. Total Hip Replacement (THR)
- The ball (femoral head) and socket (acetabulum) are replaced with artificial components.
- Materials used:
- Metal-on-plastic (most common, durable).
- Ceramic-on-ceramic (long-lasting, less wear).
- Metal-on-metal (rare due to risk of complications).
2. Partial Hip Replacement (Hemiarthroplasty)
- Only the femoral head is replaced (common after hip fractures in elderly patients).
3. Minimally Invasive Hip Replacement
- Smaller incisions, less muscle damage, faster recovery.
4. Robotic-Assisted Hip Replacement
- Enhanced precision for implant positioning.
When to Consider Hip Replacement?
- Pain interferes with daily life (sleep, walking, sitting).
- Mobility is severely limited.
- Non-surgical treatments no longer work.
