Association of patellofemoral osteoarthritis on patient-reported outcomes after medial unicompartmental knee arthroplasty: a retrospective cohort study.
Acta Orthop
January 2025
Background And Purpose: In contemporary medial unicompartmental knee arthroplasty (mUKA), non-lateral patellofemoral osteoarthritis (PFOA) is not considered a contraindication. However, we still lack knowledge on the association of PFOA severity on patient reported outcome measures (PROMs) after mUKA. We aimed to examine the association between PFOA severity and PROM-score changes after mUKA.

The external validity of the INKA trial may be hampered if the patients who participate differ from those who decline participation.
Objective: To compare baseline characteristics between patients who enrol in the INKA trial and those who decline participation (i.
Background: Medially congruent (MC) bearings aim at promoting medial pivoting after total knee arthroplasty (TKA), as the congruency provides further constraint for the medial femoral compartment. However, this design difference could alter intra-articular force distribution, potentially compromising fixation of the tibia implant. The aim of this study was to compare migration, measured with radiostereometric analysis (RSA), of an MC to a more traditional cruciate retaining (CR) TKA system.

- This study evaluates the effectiveness of ICD-10 codes in identifying postoperative complications (PCs) compared to manually reviewing electronic health records (EHRs) using data from 11,827 surgical cases in Denmark.
- Manual curation identified 1,047 PCs, while ICD-10 codes only captured 439, showing a low accuracy of about 20.8% for ICD-10 in detecting these complications.
- The study highlights that PCs significantly increase healthcare resource usage and costs, with findings indicating annual additional costs of €25.5 million, far exceeding estimates based on ICD-10 codes, underscoring the need for better detection methods for surgical quality assessment.
Article Synopsis
- There is limited research on the optimal indications for lateral unicompartmental knee arthroplasty (UKA), in contrast to the more established guidelines for medial UKA, due to differences in anatomy, osteoarthritis types, movement patterns, and surgical techniques.
- A systematic review examined 38 cohort studies to identify common indications and contraindications for lateral UKA, reporting that it is mainly performed for primary lateral osteoarthritis and identifying key contraindications.
- While some agreement on indications was found, the study indicates there is no strong consensus on the best practices for lateral UKA, highlighting the need for clearer, evidence-based guidelines in future research.
