Surgical Options

Surgery has been proven highly effective in the treatment of many knee disorders.

However, the use of arthroscopic surgery to ‘clean up’ the joint, removing small flaps of meniscal tissue and cartilage, has been conclusively shown not to help the knee OA sufferer. Yet this procedure is still widely practiced, despite the risks and costs of the surgery.

Once you understand your knee condition, you can use this section to understand the various types of knee surgery and how they may serve you.


Osteotomy is an operation which changes the alignment of the lower limb by cutting the tibia or femur, and adding or removing a wedge of bone. It is most commonly done for arthritis which is localised to one compartment of the knee. 

Autologous Chrondrocyte Implantation

Chondrocytes (articular cartilage cells) build articular cartilage by forming a matrix – a complex combination of proteins and water. When articular cartilage is damaged, it does not repair itself effectively like other tissues. Autologous Chondrocyte Implantation (ACI) involves implanting chondrocytes into an area of cartilage damage.

Exercise Physiology

Exercise Physiologist’s use exercise and physical activity for treatment and rehabilitation. For the knee OA sufferer, they will design exercise plans that achieve strengthening and functional goals, as well as a level of general fitness.


Keeping the affected lower limb and knee strong and mobile has been demonstrated to decrease knee pain, and enables the patient to exercise and maintain body weight goals which, in turn, off-loads the affected joint.

Arthroscopy, Meniscal Surgery and Lavage

Arthroscopy is a term that comes from two Greek words; ‘arthro’, meaning joint; and ‘skopein’, meaning to examine. It involves small incisions and the insertion of a small camera and special instruments to perform minor procedures.

Total And Unicompartmental Knee Replacement

Overall, 90% of patients report satisfaction with their knee replacement. In approximately 90 to 95% of people, the majority of pain is relieved, deformity (crookedness) of the leg is corrected, and mobility is improved. Range of motion averages 110 to 115 degrees but patients with significant stiffness prior to surgery tend to achieve less overall movement than others.
