Abstract
The purpose of this study was to compare the range of motion after standard version posterior stabilised TKR and high-flexion version TKR in patients receiving bilateral total knee replacement. Thirty-five patients were recruited. The range of motion of the knees was measured clinically with a goniometer in both the pre-operative period and the most recent follow-up. It was found that the pre-operative range of motion was comparable in the two groups. The average post-operative flexion was 105° ± 13° in the standard version group and 106° ± 14° in the high-flexion design group ( p = 0.201, paired t-test; beta error = 0.073). A slight loss in flexion was observed in the standard version group (0.5°) as opposed to a slight gain in the high-flexion design group (2°). However, this was not statistically significant ( p = 0.251, paired t-test; beta error = 0.105). Le but de cette étude est de comparer la mobilité du genou après prothèse totale postéro stabilisée et prothèse total type « high-flexion », tous les patients étant opérés des deux genoux dans le même temps opératoire. 35 patients ont été inclus, la mobilité des genoux a été mesurée cliniquement en pré-opératoire et au plus grand recul. La mobilité pré-opératoire a été comparable dans les deux groupes, la mobilité post opératoire a été de 105° ± 13° dans la prothèse standard contre 106° ± 14° dans les prothèses dites « high-flexion » ( p = 0.201). Une petite perte de flexion est observée dans le groupe standard (0.5°), le gain dans le groupe des prothèses dites « high-flexion » est modéré (2°). Il n’y a pas de différences significatives entre ces deux groupes ( p = 0.251).Keywords
