ADVANCES IN JOINT REPLACEMENT SURGERY
 
 
Dr Kaushal Malhan is a Joint Replacement / Resurfacing and sports surgeon at the Wockhardt hospital, Mulund. He specializes in surgery of the knee, hip and shoulder. He did the first mobile bearing uni knee replacement in India and also pioneered and popularized the technique of hip resurfacing in Mumbai. He has been in the forefront in the field of high bending total knee replacements.

MINIMALLY INVASIVE UNICOMPARTMENTAL KNEE REPLACEMENT

Most people are aware of the total knee replacement surgery. This involves replacing the unhealthy surface of the entire knee joint with metal and plastic implants. It is a very successful operation with good long term results. However a large percentage of patients have arthritis limited to one part of the joint alone. Replacing the whole joint in these patients is overkill and unnecessary.

Minimally invasive unicompartmental knee replacement is a good technique. In this operation only that part of the knee which is unhealthy is replaced. The normal surfaces are left alone. This operation has several advantages over total knee replacement surgery.
   • small incision.
   • tissue damage is far less.
   • The knee feels more natural.
   • Range of movement is full and it allows squatting and sitting crosslegged
   • Post operative hospitalization is reduced and return to normal is much faster than total knee replacement       surgery.
   • It costs less

TOTAL KNEE REPLACEMENTS THAT ALLOW FULL KNEE BENDING

A major concern for most patients planning to undergo TOTAL KNEE REPLACEMENT SURGERY is that they will be unable to sit cross-legged on the floor. For most Indian people the ability to sit cross-legged is something they cannot do without. Advanced knee replacement operations (high flexion knees) that allow such activities are available. These involve the use of special surgical technique and implants to safely increase the range of movement without jeopardizing stability and increasing wear.

  BONE CONSERVING HIP REPLACEMENT - HIP RESURFACING

 Modern techniques allow us to replace the diseased human hip with artificial implants which ensure near normal movements and function. Huge advances have been made in terms of the materials, the method of fixation and the structure of these implants. The purpose of all these changes is to increase the longevity, reduce complication rate and improved function after surgery. Resurfacing bone conserving hip replacement with a metal on metal articulation is another step in this direction.

Conventional total hip replacements usually consist of a stemmed femoral component that is fixed into the femoral canal using cement articulating with a polyethylene cup cemented into the pelvis.

PROBLEMS WITH CONVENTIONAL TOTAL HIP REPLACEMENT

 
 
 

 

 

  • Excessive bone loss
  • Increased risk of dislocation
  • Cannot squat or sit on the floor
  • Cannot safely indulge in sporting activities
  • Revision surgery difficult
  • Feels less like a normal natural hip

Alteration in leg length

The bone conserving hip resurfacing involves replacing only the diseased bone surfaces. This involves covering the femoral head with a metal cap and fixing an uncemented metal cup into the pelvis.

ADVANTAGES OF RESURFACING:

  
 
 

 

 

  • Allows the patient to squat and sit on the floor
  • Allows a normal range of movement unlike conventional THR's
  • Sacrifices only the diseased bone and preserves normal bone
  • Promises to last much longer than conventional implants
  • More natural feel after hip replacement
  • Easy to revise if needed
  • Less risk of dislocation
  • Safely allows all sporting activities soon after surgery
  • No leg length alteration
  • Ideal option for patients with osteoarthritis, avascular necrosis, ankylosing spondylitis or any other form of hip arthritis. A new feature also allows its use in hip fracture surgery or cases where the head and neck of femur are both destroyed.
