# The efficacy of unicondylar knee arthroplasty for medial compartment arthritis of the knee combined with anterior cruciate ligament dysfunction

## TL;DR

This study shows that unicondylar knee arthroplasty can be effective for knee arthritis combined with ACL dysfunction, improving quality of life.

## Contribution

The study evaluates UKA outcomes in patients with ACL dysfunction, a less commonly addressed combination.

## Key findings

- No significant differences in postoperative outcomes between normal and poor ACL function groups.
- UKA provided pain relief and improved quality of life for patients with ACL dysfunction.
- Good prognosis was observed in patients with medial compartment arthritis and ACL malfunction.

## Abstract

To investigate the outcome and prognosis after Unicondylar knee arthroplasty (UKA) in patients with medial compartment arthritis of the knee combined with anterior cruciate ligament(ACL) dysfunction.

A total of 122 patients diagnosed with knee osteoarthritis and treated with medial mobile platform unicondylar replacement at our center from January 2019 to December 2021 were retrospectively included in the study, and were divided into two groups according to ACL function, namely the normal ACL function group (ACLF) and the poor ACL function (N-ACLF) group. The postoperative results and prognosis of the two groups were evaluated and compared.

This study included 122 patients who underwent UKA surgery. There were no statistical differences in preoperative and postoperative posterior tibial tilt angle, knee mobility, KOOS, and prognosis between the two groups (P > 0.05).

For medial compartment arthritis of the knee combined with ACL malfunction, surgery resulted in pain relief, improved quality of life and a good prognosis for such patients. It is hoped that clinicians will perform UKA in patients with ACL dysfunction after a comprehensive evaluation to improve their quality of life.
