Total Versus Robotic Assisted Unicompartmental Knee Replacement

Summary

The purpose of this research is to compare the functional outcomes of patients with end stage medial compartment OA of the knee undergoing a conventional mTKA to those undergoing rUKA and to assess the associated cost economics of such technology.

* Full thickness and good quality lateral cartilage
* Correctable intra-articular varus deformity and intact medial collateral ligament
* American Society of Anesthesiologists (ASA) grades 1 and 2
* Male or female, age 50 - 75 at the time of listing for surgery
* Suitable candidate for a cruciate retaining TKA (Triathlon prosthesis) and a UKA

Exclusion Criteria:

* Varus deformity of \> 20 degrees
* Fixed flexion of \>10 degrees
* Patient is unable to comply with the study protocol (incl. refusal for CT scan) or functional assessments
* Female participants who are pregnant, lactating or planning pregnancy during the course of the study
* Requires patella resurfacing or lateral compartment has significant OA
* Inability to understand the patient information for the study, provide written informed consent or answer study questionnaires for cognitive or language reasons
* Inflammatory disorder e.g. rheumatoid arthritis
