No difference between unicompartmental versus total knee arthroplasty for the management of medial osteoarthtritis of the knee in the same patient: a systematic review and pooling data analysis.
BACKGROUND
One-third of patients with knee osteoarthritis (OA) has involvement of only one compartment, especially the medial one.


METHODS
We performed a comprehensive search of studies comparing unicompartmental knee arthoplasty (UKA) and total knee arthroplasty (TKA) in the same patient on PubMed, OVID/Medline, Cochrane, CINAHL, Google scholar and Embase databases.


RESULTS
UKA is indicated in knee with medial OA, no flexion deformity, no joint instability and no varus deformity.


RESULTS
Although high tibial osteotomy, UKA and TKA have been proposed to address medial OA of the knee, the best management is still controversial.


CONCLUSIONS
Studies investigating surgical management of medial OA of the knee are increasingly frequent.


CONCLUSIONS
Large, multicentre, powered, randomized trials comparing UKA and TKA are needed to identify the best management for medial OA of the knee. Moreover, new score systems for satisfaction of the patient should be formulated.
