Best Metal on Poly Surgery in Indore
Metal-on-polyethylene (Metal-on-Poly) is one of the most commonly used bearing surfaces in joint replacement surgeries, particularly in hip and knee replacements. This implant combination consists of a metal femoral component that articulates against a polyethylene liner, providing a balance between durability and reduced wear. Metal-on-Poly implants are widely used due to their longevity, cost-effectiveness, and biocompatibility.
Causes for Metal-on-Poly Implant Usage
The choice of Metal on Poly implants is influenced by:
- Wear Resistance: Polyethylene liners reduce friction and prolong implant life.
- Lower Risk of Metal Ion Release: Unlike metal-on-metal implants, Metal on Poly reduces ion-related complications.
- Affordability: Compared to ceramic-on-ceramic or advanced polyethylene materials, these implants are cost-effective.
- Proven Track Record: Metal-on-Poly has decades of successful clinical outcomes in joint replacement.
Common Conditions Leading to Metal-on-Poly Implant Use
- Osteoarthritis
- Rheumatoid arthritis
- Avascular necrosis
- Post-traumatic arthritis
- Hip dysplasia
- Failed previous joint replacements requiring revision surgery
Symptoms Indicating the Need for a Metal on Poly Implant
- Persistent joint pain and stiffness
- Reduced range of motion
- Joint instability or deformity
- Difficulty walking or bearing weight
- Swelling and inflammation in the affected joint
Treatment Options: Metal on Poly Joint Replacements
Non-Surgical Approaches
- Physical Therapy: Strengthens muscles to support joint stability.
- Medications: Anti-inflammatory drugs and pain relievers to manage symptoms.
- Lifestyle Modifications: Weight management, exercise, and joint-friendly activities.
- Injections: Corticosteroid or hyaluronic acid injections for temporary relief.
Surgical Treatment: Metal-on-Poly Implantation
- Total Hip Replacement (THR): A metal femoral head articulates with a polyethylene acetabular liner.
- Total Knee Replacement (TKR): Metal femoral and tibial components with a polyethylene insert.
- Partial Joint Replacement: When only one compartment of the joint is affected.
- Revision Joint Replacement: If the previous implant fails, Metal on Poly may be used as a revision option.
Recovery and Post-Surgery Care
- Hospital Stay: 2-5 days depending on the procedure.
- Physical Therapy: Essential for regaining mobility.
- Pain Management: Medications and cold therapy.
- Weight-Bearing Guidelines: Gradual resumption of activities with the help of assistive devices.
- Full Recovery Timeline: 3-6 months with dedicated rehabilitation.
