Health matters: Analysis of 91,772 knee replacement surgeries shows that about 74% of the patients were women; obesity the main culprit, says doctors
Women tend to go weak at the knees, literally. A registry maintained by the Indian Society of Hip and Knee Surgeons (ISHKS) has revealed that women are likely to go undergo a knee replacement surgery more than men. On the other hand, men are more prone to hip problems, according to the records.
Set up in 2007, the registry has so far documented 91,772 knee replacement surgeries in the country. According to its finding, 74% women underwent total knee replacement surgery. High body mass index is the reason for women being more prone to knee replacement surgeries whereas fracture leading to dislocation of the hip bones causes men to undergo surgery.
Dr Anant Pachore, ISHKS's founder president who monitors the registry said, "From October 2006 to March 2015, we had a total 1,00,018 hip and knee replacement cases. In total knee replacement (TKR) surgeries, we found that women were more prone to develop knee problem and the percentage of them undergoing TKR is higher than men."
ISHKS, which is the first Indian registry and a step towards building Indian body of evidence, showed that the average age of people undergoing TKR was 64.31 and BMI was 29.01.
Dr Shubhranshu Mohanty, orthopedic and joint replacement surgeon at KEM Hospital said, "We found that women undergoing TKR had higher BMI as compared to men. The average BMI for women undergoing TKR was 29.32 while in men it was 28.13. BMI, which indicates obesity, is closely linked to arthritis. Higher the BMI, the wear and tear of the cartilage is more. Early and fast wear and tear of the cartilages leads to need for TKR. Post TKR too, ensuring low BMI is important to avoid further complications."
According to the registry, 95% of the TKR had osteoarthritis while rest had rheumatid arthritis. Talking about total hip replacement surgeries, ISHKS found that out of the 8,246 patients undergoing THR, 61% were male. "Fracture due to a fall was the most common reason behind the THR. 45% had dislocation of hip bones, fracture due to the fall," said Dr Pachore.
The society now plans to approach the union health ministry to make it mandatory for all orthopaedic doctors practising joint replacement surgery in the country to contribute to the registry. "Presently we have 112 members regularly contributing to the registry. We need more arthroplastic surgeons to contribute so that we not get an idea about the pattern of the disease but get viable feedbacks on implants based on Indian specific data," said Dr Pachore.
