Osteoarthritis is a degenerative joint disease that results in a cartilage erosion process. This medical condition serves as a burden for the elderly population, particularly amongst people over the age of 75. Osteoarthritis of the tibiofemoral joint of the knee could be divided into either medial or lateral compartment of the joint where either result in debilitating symptoms. If other means of treatment have failed or have not provided satisfactory results surgical intervention is prompted. The current gold standard choice of surgical treatment is the procedure of unicondylar knee arthroplasty, where the main goal is to relieve osteoarthritis in the degenerative compartment in which the damaged parts of the knee are replaced. The main unicondylar knee arthroplasty procedure was designed as a means to cause less trauma compared to total knee arthroplasty by removing less bone and maintaining most of the patient’s inaugural anatomy. Moreover, it is designed in a manner of using smaller incisions with smaller implants. Therefore, reducing post-operative pain, reducing time of recovery and preserving the joint’s natural mechanism of movement.
