Iraqi women weighing 100kg undergoes rare knee replacement in Delhi hospital


IANS New Delhi
An Iraqi woman weighing 100 kg underwent a successful rare bilateral total knee replacement in Delhi's Vimhans Nayati Super Specialty Hospital, the authorities said on Wednesday.
The 65-year-old woman from Baghdad who had a BMI (body mass index) of 44.5 was suffering from difficulty in walking and severe back pain.
According to the hospital authorities, she was diagnosed with advanced osteoarthritis (Stage 4), wherein patients experience pain and discomfort in moving their joints, preventing or hampering daily activities.
"Due to bad deformity of knee joints, joint laxity and weak bones, the patient was suffering painful knees for the past 15-20 years. In this case, excess weight exerted extra pressure on her hips and knees, causing faster deterioration of the joint cartilage. She could not walk or stand for more than five minutes," said Dr Rajeev Kumar Sharma, Chairman, Institute of Orthopaedics, Sports Medicine and Arthroplasty, Vimhans Nayati Super Specialty.
The medical experts noted that with each BMI unit increase, the chances of rapid cartilage loss rise by 11 per cent. The patient also had comorbid symptoms such as diabetes and hypertension. As the high BMI makes the procedure strenuous for anaesthesia and surgery, it was done in multiple sessions.
"Since the patient was in the Class 3 (high-risk) obese category, her obesity made it a rare case. With such high BMI, total knee arthroplasty is almost impossible for the patient to endure any safe surgical procedure in routine circumstances. Besides, weak bones made the fixation of implants unmanageable," Dr Sharma added.
To ensure the benefits of this surgery last longer, backed by an improved range of motion, the medical experts used a mobile-bearing joint that can last up to 20-25 years.
"Besides, the patient's badly-stretched knee joint ligaments needed a special technique for fixing them and balancing the knee joints. We have restored the joint anatomy and limb alignment. Now, both her legs are straight with full movement of knee joints, ensuring she walks easily,"
