Abstract
Unicompartmental knee arthroplasty (UKA) faces significant challenges, including lower survival rates and higher revision rates than total knee arthroplasty (TKA). To address these issues, technological advancements like custom-made implants (CMI), patient-specific alignment (PSA), and computer-assisted systems (CAS) are being explored. These innovations aim to tailor procedures to individual joint morphology, soft tissue balance, and limb alignment, moving away from the traditional “one size fits all” approach. Early studies suggest that CMI may improve survival rates and patient-reported outcomes, though conclusive evidence is lacking. PSA shows potential for restoring pre-surgical alignment; however, its long-term benefits are uncertain. CAS improves implant placement precision and ligament balance; nevertheless, long-term survival data remain inconclusive. Moreover, economic and implementation challenges, such as cost and the need for specialized training, remain underexplored. While promising, further research is needed to fully understand the long-term efficacy and practical application of these technologies in UKA.
