Total Knee Replacement
Side effects are symptoms that occur after every operation and are a normal part of the recovery from the operation. The main side effects of knee replacement surgery are:
- Knee pain
- Swelling of the knee and bruising around the knee
- Stiffness of the knee
Complications are uncommon problems that occur during or after the operation. Most people having hip surgery aren't affected.
The general complications for all operations are:
- A reaction to the anaesthetic
- Infection of the wound or joint
- Excessive blood loss
- A blood clot, usually in a vein of the leg (known as a deep vein thrombosis or DVT)
Complications that are specific for total knee replacement surgery include:
- Ongoing knee pain: The main reason for having a knee replacement is persistent knee pain. A knee replacement is usually a very effective method of relieving knee pain. It is important to know however that a small number of patients have ongoing knee pain after their operation. Between 6- 17% of patients having a knee replacement will have ongoing pain after their operation.
- Stiffness. Stiffness of the knee after surgery can occur and it is important to work hard on your rehab exercises to minimise this problem.
- Wearing out of the replaced knee: Although you have a new knee after your procedure it still undergoes wear and tear due to your everyday activities. 94% - 97% of knee replacements will last at least 12 years
- Nerve damage: Nerves can be injured during the operation. The chance of getting nerve injury is very low.
- Dislocation: Very rarely after your operation your knee can become unstable and actually dislocate or pop out of place.
- Fracture: After your knee replacement there is a small chance that the bones around the metal can break.
