Die Flexion zur Entlassung ist kein Prädiktor der Gelenkfunktion ein Jahr nach Knietotalendoprothese
OBJECTIVE: In total knee arthroplasty (TKA), range of motion has become established as an important factor. The criterion of quality is set to flexion of 90° after hospitalisation. Currently, it is supposed to be a predictor for 1‑year postoperative outcome. However, as this correlation has not been...

Sumario: | OBJECTIVE: In total knee arthroplasty (TKA), range of motion has become established as an important factor. The criterion of quality is set to flexion of 90° after hospitalisation. Currently, it is supposed to be a predictor for 1‑year postoperative outcome. However, as this correlation has not been proven, this clinical trial was performed. METHODS: A total of 182 TKA recipients were analysed retrospectively. Outcomes were assessed before surgery, after hospitalization, 6 weeks and 1 year post surgery. They included knee range of motion (ROM) to answer the main hypothesis, but also KSS, SF-36, WOMAC, EQ-5D and VAS to evaluate knee function and quality of life. The patients were divided into two groups differing in achieving 90° flexion after hospitalisation and compared 6 weeks and 1 year after surgery. RESULTS: Knee flexion differed significantly between groups from 91 to 70° in the group without the aim of 90° flexion after hospitalisation (E) (p < 0.001). After 6 weeks, flexion was improved to 112° ± 13° (E > 90°) vs. 106° ± 14° (E < 90°; p = 0.001). One year post surgery, knee flexion averaged 122° ± 10° (E > 90°) vs. 120° ± 10° (E < 90°) with no difference between the groups (p = 0.57) and no significant difference in all other scores concerning knee function and quality of life. CONCLUSION: Flexion of 90° after hospitalisation is not adequate to predict medium-term outcomes after TKA. There is no advantage or disadvantage regarding whether the aim of 90° flexion is achieved. |
