Chennai, India, December 23, 2005 --(PR.com
)-- A 56-year-old marine engineer from the United Kingdom has recently undergone a "mobile bearing unicondylar" knee replacement surgery in a private hospital here, through a minimally invasive approach by making an incision of only three inches.
Dr A K Venkatachalan, consultant orthopaedic surgeon at the private Venkateswara Hospital, who performed the surgery, told reporters that unicondylar knee replacement was ideally suited for middle-aged women with partial knee arthritis.
"Men with a similar problem will benefit from a high tibial osteotomy. This is the first such surgery in Tamil Nadu," he claimed.
Explaining the procedure, the surgeon said unicondylar knee replacement substituted the inner or outer worn half of the joint with prosthesis.
"The bony resection is restricted to the affected half alone, sparing the unaffected half and the patella, unlike in a total knee replacement."
The pre-requisite for such surgeries was that the inner half alone must be worn out and the anterior cruciate ligament should be intact, he said adding that the technique of insertion was demanding but the rewards to the patient were numerous like shorter stay in the hospital, quicker recovery, small incision, no blood transfusion and less cost.
"Those who had undergone such surgeries can squat, kneel and climb stairs very soon as the knee feels more natural as sensations carried by the ligaments are intact," the surgeon explained.
The engineer, Cliff Arkley, hailing from Sussex, was discharged a fortnight ago. (Our Correspondent)
