Knee replacement surgery, commonly referred to as knee arthroplasty, is a widespread orthopaedic surgery. This surgery is performed to treat the defects of knee cartilage caused by disease, damage or injury. Knee replacement surgery consists of two main procedures. These operations are total knee replacement and partial knee replacement. Around 70% of patients opt for total knee replacement surgery.

Our knee consists of three parts – the lateral, the medical and the patellofemoral.  If all the parts are severely damaged, total knee arthroplasty surgery is needed. The possible damages can include meniscus tears, cartilage tears and ligament tears. In addition, certain types of arthritis such as osteoarthritis, rheumatoid and post-traumatic arthritis are prevalent reasons of knee pain and disability.
