Knee Replacement Surgery Kenya
Knee replacement , also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability.
What is a total knee replacement?
Knee replacement, also called arthroplasty, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury. In this procedure, the knee is replaced with an artificial joint. It requires a major surgery and hospitalization.
Partial knee replacement?
The surgeon replaces the damaged portions of the knee with plastic and metal parts.
Knee Replacement surgery Kenya Procedure
• |The orthopedic surgeon makes a cut down the front of your knee to expose your kneecap. This is then moved to the side so the surgeon can get to the knee joint behind it.
• The damaged ends of your thigh bone and shin bone (tibia) are carefully cut away. The ends are correctly measured and shaped to fit the appropriately sized prosthetic replacement. A dummy joint is positioned to test that the joint is working properly. Adjustments are made, the bone ends are cleaned, and the final prosthesis is fitted.
• The end of femur is replaced by a curved piece of metal, and the end of your tibia is replaced by a flat metal plate. They are fixed using special bone ‘cement’, or are treated to encourage bone to fuse with the replacement parts.
• The back of the knee cap may also be replaced, depending on the reasons for replacement.
• The wound is closed with either stitches or clips and a dressing is applied to the wound.
Total knee replacement protocol
How many years does knee replacement last?
If you have your total joint replaced today, you have a 90-95% chance that your joint will last 10 years, and an 80-85% that it will last 20 years.
When can you drive after knee replacement surgery?
Most surgeons allow patients to drive at 4 to 6 weeks after surgery, and sometimes sooner if the operative leg is the left leg. There is some literature that states that your reaction time will not be back to normal prior to 6 weeks.
Activities after Knee Replacement Surgery
The exercises that you perform after surgery help strengthen your knee and improve flexibility so that you can quickly get back on your feet. It’s important to commit to a rehab plan and work with your surgeon and physical therapist to set goals.
How long does it take to recover from a total knee replacement?
It can take up to 3 months for you to return to most activities, and likely 6 months to one year to fully recover to maximal strength and endurance following a TKR. This depends on your condition before surgery, additional medical problems, and your expectations.
Knee replacement surgery Kenya complications
Knee replacement complications can be caused by the surgery or a faulty implant. Complications can include implant failure, infection and fracture.
knee replacement Surgery Kenya infection
A small percentage of patients undergoing hip or knee replacement (roughly about 1 in 100) may develop an infection after the operation.
Knee replacement infection amputation
In certain situations, when other treatment options have been exhausted, patients with a failed total knee replacement may become candidates for above-the-knee amputation.
Surgical alternatives to knee replacement Surgery Kenya:
Arthroscopic washout and debridement
Autologous chondrocyte therapy (ACT)
Non Surgical Knee replacement Alternatives
Most doctors recommend non-surgical (conservative) treatments before considering a knee replacement. These include:
• Diet – Losing weight will reduce the strain on your knee.
• Exercise – Even though this may be difficult because of the pain, there’s usually some form of non-impact exercise (for example swimming or cycling) that you can start gently and which will improve the strength and flexibility of your knee.
• drugs – Painkillers can reduce the pain in your joint, while non-steroidal anti-inflammatory drugs (NSAIDs) may help if your knee is swollen
