I was suffering from severe arthritis
in both knees since several years, and Dr. Anuj Agrawal did bilateral knee replacement for my knees. I
was extremely satisfied by the outcome of the surgery. Contrary to my expectations, I didn’t have any
significant pain just 3 days after surgery, and could walk without support at 2 weeks. I have a low
sitting at my office, and have no problem in sitting cross-legged on the floor after surgery. I highly
recommend Dr. Anuj for knee replacement surgery based on my experience. 
I underwent bilateral knee replacement
in a single sitting for my knee pain at Max Hospital, Patparganj. My surgeon DrAnuj Agrawal took good
personal care of me, right from the time of admission till discharge. I was apprehensive that a
bilateral surgery would be very painful with a prolonged rehabilitation period. However, I was
painfree within 2 weeks of surgery and could get back to work within 6 weeks. I recommend DrAnuj
Agrawal for his expertise in joint replacements.
I had arthritis of both my hips due to
a condition called avascular necrosis. I used to walk with severe limp, and could not sit properly due
to the condition of my hips. Dr. Anuj Agrawal did uncemented hip replacements for both my hips, at an
interval of 6 weeks. I could walk without support just 2 weeks after the second surgery and could even
ride a scooter at 1 month. I have become completely painless now, and am quite happy by the outcome of
the surgery. I would highly recommend Dr. Anuj Agrawal for hip replacements.
The hip joint is a ball-and-socket joint, and has a great deal of inherent mobility. The hip is even more important for mobility than the knee. Any disease involving the hip joint leads to immense difficulty in walking, and results in severe disability. Once the destruction of the hip joint occurs, like in knees, Hip Replacement surgery remains the only option. Dr. Anuj Agrawal is the best hip replacement surgeon in Delhi NCR. Hip Replacement surgery has been in vogue for over 50 years, much before knee replacements became popular, and has consistently given pain free mobility to millions of patients worldwide. Consult with best hip replacement surgeon in Delhi NCR.
Unlike knees, primary osteoarthritis of the hips is not commonly seen in Asian populations. But, hip joints might develop secondary osteoarthritis following osteonecrosis (AVN), infections (including tuberculosis), trauma (ball and socket fractures) and childhood hip diseases such as developmental dysplasia (DDH), Perthe’s disease, etc. Inflammatory arthritis including ankylosing spondylitis and rheumatoid arthritis also commonly involve the hip joint. Fractures of the hip are common in elderly due to weakened bones (osteoporosis) and predisposition to falls. Traditional fixation of these fractures with screws or nails is not successful in all cases, and partial or total hip replacement is commonly required in these.
Total hip replacement (THR) involves replacement of both the ball (femur) and socket (acetabulum) of the hip joint. The femoral component is a modular one, consisting of a stem (made of metal such as cobalt-chrome or titanium) and head-neck (made of metal or ceramic). The acetabular component can be made of ceramic, metal or plastic (UHMWPE). The components are fixed to the parent bone by either bone cement (cemented hips) or by natural bone ingrowth/ongrowth over special porous or roughened surfaces (uncemented hips). Uncemented hips are costlier than cemented hips, and are supposed to have longer survivorship.
Diseases of the hip are commonly seen in young people, and hence, hip replacements should have high survivorship over 30 to 40 years. This has been achieved with the newer high-performance bearing materials like ceramic, oxinium and highly cross-linked poly. Hence, unlike knee replacements, hip replacements can even be done in adolescents, if required.
If only the ball (femur head) of the hip is affected, as commonly seen after hip fractures, only the femur head can be replaced in a partial hip replacement or hemiarthroplasty, and the native cup (acetabulum) is left untouched. The advantages of hemiarthroplasty over total hip arthroplasty are decreased surgical duration, morbidity and costs. However, the long term survivorship of hemiarthroplasty is limited (10-20 years), after which the native acetabulum wears out, and then it has to be converted into a total hip replacement. Hence, hemiarthroplasty is applicable only for elderly, low-demand patients, and total hip arthroplasty is the preferred surgery for younger patients (even if the acetabulum is healthy).
