Abstract
Purpose
The objective of this study was to evaluate the functional and radiological outcome after lateral tibial plateau fractures (Müller AO classification (AO) 41-B1, B2 and B3) treated with minimal invasive bone tamp reduction and percutaneous screw fixation.
Methods
Retrospective, cross-sectional study. Review and clinical examination of 37 patients treated between 2005 and 2010. The patients completed a clinical examination, Knee Injury and Osteoarthritis Outcome Score (KOOS) and questionnaire evaluating QOL (Eq5D-5L).
Results
Thirty-seven patients agreed to participate (76 %). Mean time of follow-up was 5.2 years. At final follow-up, maintained anatomical joint reduction was achieved in 34 patients. The mean KOOS score was pain = 84.4, ADL = 88.4, symptoms = 80.7, QOL = 70.3, sport = 59.6. Compared with the established KOOS reference population patients, the current study reports a tendency towards worse KOOS scores but is only significant for KOOS sport. The mean Eq5D-5L index was 0.815 and shows a tendency towards worse outcome compared with the reference population. Mean knee flexion: 125.7° (95–135). A reduced number of sit-to-stands in the mean 30-s chair stand test showed a significant negative association with KOOS. The study showed a significant association between younger age at surgery and worse KOOS outcome.
Conclusion
At 5.2-year follow-up, the patients reported a tendency towards worse KOOS and Eq5D-5L scores compared with established reference populations. This study shows a significant association between a decrease in muscle strength and worse KOOS outcome. Furthermore, a significant association between younger age at the time of surgery and worse KOOS outcome score was observed.
