When the knee is severely damaged or hurt due to arthritis or injury, it becomes difficult to perform even simple activities, such as walking or climbing stairs. When the patient’s activities in their day to day life start getting hampered and if nonsurgical treatments like medication, exercises, icing, heating, knee supplements, and using walking supports are no longer helpful, then we opt for surgical interventions in the form of either a Total Knee Replacement or a Partial Knee Replacement.
Total Knee Replacement:Depending on the condition of articular cartilage of the knee cap, some bone and cartilage from the ends of the thigh bone and shin bone may be removed. It is resurfaced by metal (cobalt chrome alloy) on the thigh bone side and a metal plate on which sits a plastic insert (ultra-high-density polyethylene) on the shin bone side. The knee cap is replaced with plastic. These implants are attached to the bone with special bone cement.
Minimally Invasive Muscle Sparing Knee Replacements:
- Traditional – In this surgery, the knee is opened by an incision, with a cut through the quadriceps tendon. The incision is around 8-10 inches.
- Minimally Invasive Muscle Sparing Approach – With medical advances in Total Knee Replacements, there is more emphasis on causing minimal tissue trauma during surgery.
The main advantages of this muscle-sparing approach are: –
- Lesser post-operative pain,
- Shorter hospital stays (Average 2-3 days),
- Less blood loss,
- Quick rehabilitation and very early return to function. (Almost three times faster),
- Higher patient confidence.
