Who need a Knee Replacement?
People who experience severe knee pain that limits their activities, have knees that are often swollen and not responding to medications or rest, have deformed knees, have knees that are stiff and difficult to bend or straighten, and do not get satisfactory relief from pain killers and other conservative methods may be candidates for knee replacement surgery. However, it is important to consult with a qualified healthcare provider to determine if knee replacement is the appropriate treatment option for an individual’s specific condition.

Knee Surgery Procedure
During knee replacement surgery, the worn and damaged surface of bone and cartilage from the lower end of the femur (thigh bone) and upper end of the tibia (shin bone) are removed and shaped to accept the prosthetic implants. This is typically done through a midline incision on the front of the knee. The joint is exposed after separating the muscle and cutting through the capsule.

This is typically done through a midline incision on the front of the knee. The joint is exposed after separating the muscle and cutting through the capsule.
The surfaces are replaced with metal and plastic implants that closely
mimic the natural knee motion and function. The soft tissues around the knee
are carefully balanced to correct the alignment of the joint and optimize the
function of the knee.
After the procedure, the incision is closed and the patient is moved to a recovery room. The patient may spend a few days in the hospital to recover, depending on their individual needs and the type of knee replacement surgery they underwent. Physical therapy is typically started soon after the procedure to help the patient regain strength and mobility in their knee.
After total knee replacement surgery, there are several important points to keep in mind:
1. Walking and limited post-operative exercises are important and should be performed as instructed by your physiotherapist. These exercises are usually prescribed to help regain strength and mobility in your knee and should be continued for life.
2. Balance rest and activity, especially early in your recovery. It is important to avoid overexerting yourself, while still maintaining some level of activity to promote healing.
3. Follow instructions to prevent blood clots. Your healthcare team will likely provide you with instructions on how to prevent blood clots, such as performing leg exercises and wearing compression stockings.
4. Know the signs of infection, such as fever, increasing redness or warmth around the knee incision, and discharge or bleeding from the wound. If you experience any of these symptoms, contact your healthcare provider immediately.
5. Be careful and avoid falls. Your balance may be affected after surgery, so it’s important to take precautions to prevent falls.
6. Carefully adhere to restrictions. After surgery, you will likely be advised to avoid high-impact activities like running or jumping, and extreme knee bending or squatting. These restrictions help prevent wear or early loosening of the implants.
7. Follow up with your healthcare provider as instructed. Regular check-ups are important to monitor your progress and address any concerns that may arise.
