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.
AIM
To summarize and analyse the causes of revision after UKA.
METHODS
This is a retrospective case series study in which the reasons for the first revision after UKA are summarized. We analysed the clinical symptoms, medical histories, laboratory test results, imaging examination results and treatment processes of the patients who underwent revision and summarized the reasons for primary revision after UKA.
RESULTS
A total of 13 patients, including 3 males and 10 females, underwent revision surgery after UKA. The average age of the included patients was 67.62 years. The prosthesis was used for 3 d to 72 months. The main reasons for revision after UKA were improper suturing of the surgical opening (1 patient), osteophytes (2 patients), intra-articular loose bodies (2 patients), tibial prosthesis loosening (2 patients), rheumatoid arthritis (1 patient), gasket dislocation (3 patients), anterior cruciate ligament injury (1 patient), and medial collateral ligament injury with residual bone cement (1 patient).
CONCLUSION
The causes of primary revision after UKA were gasket dislocation, osteophytes, intra-articular loose bodies and tibial prosthesis loosening. Avoidance of these factors may greatly reduce the rate of revision after UKA, improve patient satisfaction and reduce medical burden.
Core Tip: Despite the many advantages of unicompartmental knee arthroplasty (UKA), the long-term survival rate of implants and the rate of UKA revision remain controversial. Therefore, clarifying the reasons that may cause UKA revision can further reduce the revision rate of UKA surgery. We found that the main reasons for the initial revision of UKA were gasket dislocation, osteophytes, intra-articular loose bodies and tibial prosthesis loosening. Avoiding these factors may greatly reduce the revision rate after UKA surgery, improve patient satisfaction, and reduce medical burden.
