Knee Osteotomy


A knee osteotomy is a procedure to realign the knee joint to reduce pressure on the worn area of your knee, improve mobility and reduce pain. This is achieved by cutting and reshaping either the thigh bone or shin bone to shift alignment so that the body weight passes through the good side of the knee rather than the worn side.


A knee osteotomy can be recommended when you have damage to the knee or osteoarthritis and physiotherapy and steroid injections have not alleviated symptoms. It is a good alternative to a total knee replacement when the damage is confined to only one side of the knee joint.


Mr Chatoo and Mr Thakrar,  Knee Osteotomy

Adult single and double level knee osteotomies are performed at One Hatfield Hospital by specialist surgeons Mr Minhal Chatoo and Mr Raj Thakrar. They work together at Lister Hospital, one of only a few regional centres providing a knee osteotomy service, and they replicate this service in their private clinics here at One Hatfield. 


Typically, patients who have a knee osteotomy are younger than 60 and active, but anyone is suitable if it is thought that the results of a knee osteotomy will be better for the patient than a total knee replacement. The need for a total knee replacement can be delayed for many years or avoided altogether.


What is Osteoarthritis?

The knee joint is formed of the lower thigh bone, the upper shin bone and the knee cap (patella). Normally the knee allows the thigh and shin bone to slide over each other due to the smooth cartilage which covers them and lines the underside of the kneecap. 


When osteoarthritis occurs the cartilage becomes rough and causes pain and stiffness in the joint. When the cartilage wears unevenly it can shift alignment of the bones causing the knee to bow inward or outward. A knee osteotomy realigns the bones to prolong the life span of the knee joint.


Osteoarthritis mainly affects people over 50, and the likelihood of having it will increase with age.


What happens during this procedure?

Prior to the procedure scans will be analysed to work out exactly what degree of adjustment is required. This will determine the measurements of the opening or closing wedge.


This surgery can be performed under general anaesthetic or spinal anaesthetic.  A spinal anaesthetic will numb you from the waist down but you will remain awake.  A sedative can be given to relax you.


Your surgeon will make an incision over the area of bone to be reshaped, either the thigh bone or, most commonly, the shin bone.


Depending on whether you need an opening or closing wedge, your surgeon will either cut a wedge into the bone so it can be pulled slight apart to open a gap. The wedge is measured and fixed in place with a plate and pins. This is an ‘opening wedge’ osteotomy. Alternatively, the bone is cut to remove a wedge. The cut edges of the bone are brought together and held in place with a plate and pins. This is a ‘closing wedge’ osteotomy.


The surgery typically takes one to two hours.


How long will it take to recover and what results can I expect?

Patients will be able go home the day after surgery. You will be able to bear weight and move your knee straight away because the joint itself isn’t affected by surgery. A physiotherapist will assess your mobility before you leave the hospital, and work with you to devise an exercise plan to get you back to your normal level of activity. Full range of movement is encouraged as soon as possible.


You can take pain relief medication as required for the days after surgery, but avoid anti-inflammatories. You will only have light surgical dressing, no brace will be required, but you will need crutches for 4 – 6 weeks.


Everyone is different so your consultant will advise you at a follow up appointment when you will be ready to return to normal activities.  As a guide, patients will usually be able to return to driving and work after 6 weeks (you may need longer if you have a manual job) and will have made a full recovery after 6 months.


The results of this procedure are excellent. Patients can usually run, jump, kneel and fully bend the knee joint which is not possible with a knee replacement.


In most cases, knee osteotomy relieves arthritis pain and postpones the need for a total knee replacement by 10 to 15 years.
