ARTICLE HIGHLIGHTS
Research background
Unicompartmental knee arthroplasty (UKA) has great advantages in the treatment of unicompartmental knee osteoarthritis, but its revision rate is higher than that of total knee arthroplasty.
Research motivation
Providing a reference for orthopaedic surgeons to reduce the revision rate and improve patient satisfaction.
Research objectives
The study aims to summarize and analyse the causes of revision after UKA.
Research methods
This is a retrospective case series summarizing the reasons for the first revision after UKA in the Department of Orthopedics of Guangdong Provincial Hospital of Traditional Chinese Medicine from November 2016 to December 2020. We analysed data on the clinical symptoms, medical history, laboratory tests, imaging examinations and treatment process of the revision cases and summarized the reasons for primary revision after UKA among all cases.
Research results
Thirteen patients, including 3 males and 10 females, underwent revision surgery after UKA. The average age of the included patients was 67.62 years. The main reasons for revision after UKA were improper suturing of the surgical opening, osteophytes, intra-articular loose bodies, tibial prosthesis loosening, rheumatoid arthritis, gasket dislocation, anterior cruciate ligament injury, and medial collateral ligament injury with residual bone cement.
Research conclusions
The causes of primary revision after UKA were gasket dislocation, osteophytes, intra-articular loose bodies and tibial prosthesis loosening.
Research perspectives
Avoidance of these factors found in this study may greatly reduce the rate of revision after UKA, improve patient satisfaction and reduce medical burden.
