The individual rehabilitation period varied between 12 – 25 days, included 48.1 ± 12.5 (THA) or 41.9 ± 9.7 (TKA) exercise interventions with intensities between 9.6 and 14.0 points on the Borg Rate of Perceived Exertion Scale. WOMAC pain (P<.001), stiffness (P<.001) and function (P<.001) as well as hip (P<.001) and knee (P<.001) ROM improved significantly in THA and TKA patients. ANCOVA showed that these changes could not be explained by the total duration or mean intensity of exercise therapy.


The findings show a low dose-response relationship between early postoperative exercise therapy and the improvements in function or range of motion following THA and TKA.
