Mr Khosrow Sehat answers questions about knee replacement surgery

31 July 2019

Who may benefit from knee replacement surgery?

Patients with severe arthritis of the knee who are experiencing marked pain and loss of function of the knee may be suitable for knee replacement surgery and may wish to consider this treatment option, if non-surgical treatment has not been successful.

Osteoarthritis is the most common form of arthritis. The cartilage surfaces on the bones in the joint are worn and damaged, resulting in pain.

What does knee replacement surgery involve?

Essentially, the cartilage surfaces that have been worn and damaged are replaced with an artificial implant that replicates the original surface of the joint.

What determines how well the knee replacement will function?

Knee replacement surgery is the most effective and commonly performed treatment for end stage arthritis. A significant reduction in pain is achieved in the majority of cases. There can also be a significant improvement in walking ability. However, knee replacements do not generally function as well as a healthy knee. Many factors influence how well a knee replacement will function and it is not possible to predict a specific outcome. One important factor is the degree of ‘individualisation’ of the surgery and the positioning of the implant to suit the specific nature of any individual patient’s knee.

What are the most effective types of knee replacement?

Advanced technologies which aim to achieve the best possible outcomes in knee replacement surgery are available at Spire Nottingham Hospital and performed by Mr Khosrow Sehat, Consultant Orthopaedic Surgeon.

Computer guided surgery is used to maximise the accuracy and individualisation of the implant positioning. This is coupled with monitoring by computer of the rehabilitation after surgery to ensure the best outcomes. The implant used by Mr Sehat is the ‘AS Columbus’ knee replacement. This implant has a unique advanced surface ceramic coating which greatly increases its toughness, durability and resistance to adverse reactions. These surgical techniques and material have been shown to offer the most effective and reliable results for patients.

Should I consider a knee replacement operation?

This operation is effective in relieving severe pain in the majority of patients with marked arthritis. In England and Wales, 90,000 patients each year have this operation as it is considered an effective treatment in relevant situations.

The availability of this surgery has been restricted within the NHS. If you are experiencing severe pain in your knee and are affected by arthritis, you may wish to consider being assessed for the suitability of surgery or other appropriate treatments such as injections or physiotherapy.
