A myriad of diseases and conditions can cause the knee joint to become damaged. Arthritis is one of the leading causes of knee joint damage. Sometimes arthritis can be severe enough to disable the joint completely. This results in pain and a loss of mobility of the knee joint.
In such cases, medications and arthroscopic repair surgery are the first lines of treatment. If they fail, a total or unicondylar knee replacement surgery can be considered.
Why is a Unicondylar Knee Replacement Surgery Performed?
This surgery aims to relieve the pain and functional disability of the knee joint so that the patient can walk with confidence again.
Imaging tests like X-rays will reveal the extent of damage in the joint. If the entire joint is involved a total knee replacement surgery will be advised. However, if only one condyle of the knee is damaged, a half-knee replacement surgery or a unicondylar knee replacement surgery is performed.
What Happens in a Unicondylar Knee Replacement Surgery?
The patient is operated under general, and the surgery may be an open one or minimally invasive surgery. Although traditional open surgery is more common, minimally invasive surgery has a much better prognosis.
During the operation, the damaged parts of the condyle involved are removed. This includes damaged tissue and cartilage. The half knee removed is then replaced with a metal and plastic implant. The metal makes the centrepiece that fits in the plastic (polyethene) covering. Metals commonly used in these types of surgeries are titanium, stainless steel or certain alloys of chrome and cobalt.
What Happens After Surgery?
A half-knee surgery has an early recovery time than total knee replacement surgery. With proper post-operative care and physiotherapy, you can expect to return to your daily activities in only a few weeks.
