Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

the present study will conduct to assess anterior knee pain and complications after medial UKA with or without patella denervation in medial compartment arthritis and severe lateral facet patellofemoral arthritis patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this prospective cohort study, the investigators will conduct to compare the clinical result of 70 patients of unicompartment knee arthroplasty with and without patella denervation between April, 2018 and April, 2019 for the patients with osteoarthritis.
