PRIMARY TOTAL KNEE REPLACEMENT
Total knee replacement known as the knee arthroplasty is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and any disability. It is most commonly performed for osteoarthritis, rheumatoid arthritis and psoriasis arthritis.
The surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped that will ensure pain-free mobility to the individual.
COMPUTER AIDED HIP & KNEE NAVIGATION SURGERIES
Accuracy of component placement is essential in improving the function & longevity of joint replacement surgery along with a preplan that is customized for the patient. We use computer navigation systems designed to improve the accuracy of component placement to optimize outcomes.
PARTIAL/UNICONDYLAR KNEE REPLACEMENTS
Total Knee Replacement is not necessarily the only solution for all types and stages of painful arthritis. Sometimes, only one compartment is predominantly affected. These situations are best suited for joint-conserving procedures like Unicondylar replacement. Since all the ligaments are preserved and the procedure is minimally invasive, the recovery is rapid and functions near normal.
OSTEOTOMIES (Realignment of bone)
Joint preservation surgery is meant to realign the knee and to take pressure off the damaged side. The weight-bearing part of the knee is shifted from degenerative or worn tissue onto the healthier tissue. In the recent times as the incidence of arthritis in young patients is growing enormously, this is a preferred alternative for young active patients who suffer from arthritis and osteoarthritis instead of opting for a knee replacement surgery.
OXINIUM (CERAMIC) KNEES
An Oxinium-knee reduces the wear by significantly enabling the employment of the knee replacement procedure for relatively younger patients, who may not get advised a conventional knee replacement due to potential early failure.
PRIMARY TOTAL HIP REPLACEMENTS
Conventional Total Hip Replacement (THR) is a very successful procedure for the treatment of arthritis of the hip – a condition causing considerable pain and loss of movement. The joint is made up of the head of the femur (the ball), which fits into the acetabulum (the socket). Total hip replacement surgery replaces the upper end of the thighbone (femur) with a metal or ceramic ball and resurfaces the hip socket in the pelvic bone with a metal shell and plastic/ceramic liner.
REVISION KNEE REPLACEMENTS
Conventional joint replacement is a very successful procedure for the treatment of arthritis however the main complication with any joint replacement is the gradual wear which eventually reaches a point where the replacement joint no longer functions properly. A Revision Total Knee Replacement is a procedure in which we remove previously implanted artificial knee joint, or prosthesis, and replace it with a new prosthesis.
REVISION HIP REPLACEMENTS
Revision hip replacement surgery is a procedure to replace a worn-out hip replacement implant which could be due to various reasons. By far the most common cause of a hip replacement wearing out is called aseptic loosening. While the others include infection, breaking of the prosthesis or the bone around the prosthesis, and other complications. Depending on the cause of the implant failing, revision hip replacement can be sought.

frequently asked questions
What is Total Knee Replacement?
A total knee replacement is a surgical procedure for replacing the knee joint. This joint is composed of three parts – lower end of the femur (thigh bone), the upper end of the tibia (shin bone) and patella (knee cap). During the surgical procedure, diseased surfaces of the knee joint are removed and replaced with smooth artificial surfaces.
When do we consider Joint Replacements?
Total knee replacements are usually performed for severe arthritic conditions that hinder not only work and recreation but also the ordinary activities of daily living, especially walking.
Consider Joint Replacements if -
- you are on regular medication
- X-rays show advanced arthritis
Getting ready for your operation
- Keep your weight in check
- Check for dental hygiene
- Rule out infections
- Keep yourself fit as it will speed your recovery and reduce the risk of complications
This is done to assess you for surgery :
- Fresh x-rays and blood tests will be taken
- Questionnaire about your current health and past medical, surgical and medication history
- Bring all your current medication and prescriptions by your doctor
- If you suffer from high BP, then the same will be monitored regularly
- If you are diabetic, please bring a record of your blood sugar readings
- If you are on Warfarin, Aspirin or other blood thinners, please let us know as this will impact surgical decisions
- Smokers must stop it prior to surgery to lessen the likelihood of a postoperative chest infection
- You might require iron tablets to build up your bodies iron stores ready for surgery
Admission to Hospital
Usually, you are admitted in the hospital a day before the surgery :
- The anesthetist will talk to you and assess the most suitable form of anesthesia
- Our anesthetist may recommend a pre-medication to be given some hours before surgery
- A period of fasting i.e. nothing to eat or drink for some hours before surgery is necessary to reduce the risk of vomiting
- A shower is mandatory before surgery post which the side of surgery will be marked
After your Surgery
- You will be kept under observation and monitored until you have recovered from the effects of the anesthetic
- There will be an intravenous infusion (drip in your arm) and drain tubes coming out of your thigh for 24 hours or so. These prevent excess postoperative blood collections
- Nausea and sickness are common side-effects of the general anesthetic and painkillers
- You will be given oxygen through a mask for a few hours
A combined multimodal approach is used for effective pain management which resulted in pain free recovery and early ambulation.
After your Operation
- Physiotherapists will demonstrate leg exercises that you will need to do once you feel better enough to sit onto the side of the bed/ stand using a frame
- You will have to begin walking with the help of a walker and attempt knee bending exercises
- Practice walking daily as soon as you are able to start using elbow crutches
- You are ready for discharge depending on your fitness
Post Discharge – At Home
- It is important you continue with your exercises
- The success of the operation has a lot to do with how well you do your exercises as that will strengthen your muscles
- Wound stitches or staples are removed around the fourteenth day after surgery
- Look for warning signs - If you notice any swelling, increased pain, drainage from the incision site, redness around the incision, or fever, you should report this immediately to your doctor
Prevention of Infection
If at any time (even years after your surgery) you develop a bacterial infection such as a sore throat or significant chest, urinary infection or cellulitis (redness and swelling of the limb) you should inform us or your nearest doctor of your knee replacement. Antibiotics should be administered promptly to prevent the occasional complication of distant infection localizing in the joint area. This also applies even if you have a tooth extraction.
Do’s and Don’ts:
- Perform all the exercises as instructed by your physiotherapist
- Take regular short walks
- Keep walking with your walking aids until 2 to 3 weeks after your operation
- Gradually progress to 1 walking stick held in the opposite hand to your new knee
- Avoid pressure on the wound until it has fully healed and keep the wound dry until the skin has fully healed
- Report to us immediately if you have any unusual pain, swelling, notice a discharge from your wound or any pain or swelling in your calves
- Take regular painkillers for as long as you need to
- Eat a balanced diet with plenty of fresh fruit and vegetables
- Twist the operated leg in or out whilst sitting or standing for at least 3 months
- Cross your legs, knees or ankles for at least 3 months
- Sit on low chairs, stools or toilets
- Do attempt any heavy lifts, or housework and gardening that involve heavy lifting
- Discard any walking aids until advised to do so
