Abstract Background Dynamic augmentation of anterior cruciate ligament tears seems to reduce anteroposterior knee translation close to the pre‐injury level. The aim of the present study is to biomechanically investigate the course of translation during a simulated early post‐operative phase. It is hypothesized that anteroposterior translation is maintained at the immediate post‐operative level over a simulated rehabilitation period of 50’000 gait cycles. Methods Eight fresh‐frozen human cadaveric knee joints from donors with a mean age of 35.5 (range 25–40) years were subjected to 50’000 cycles of 0°‐70°‐0° flexion‐extension movements in a custom‐made test setup. Anteroposterior translation was assessed with simulated Lachman/KT‐1000 testing in 0°, 15°, 30°, 60° and 90° of flexion in knee joints treated with the novel technique initially and after 50’000 cycles testing. Statistical analysis was performed using the Wilcoxon Signed‐Rank Test. The level of significance was set at p = 0.05. Results Anteroposterior translation changed non‐significantly for all flexion angles between cycle 0 and 50’000 (p = 0.39 to p = 0.89), except for 30° flexion, where a significant increase by 1.4 mm was found (p = 0.03). Conclusion Increase in anteroposterior translation of knees treated with this dynamic augmentation procedure is low. The procedure maintains translation close to the immediate post‐operative level over a simulated rehabilitation period of 50’000 gait cycles and therefore supports anterior cruciate ligament repair during biological healing. |
