Change in KOOS-QOL of greater than 10 points was used to establish minimally clinically important change (MCIC), with chi square analyses used to assess between-group differences.\u0000 \u0000 \u0000 \u0000 Baseline KF-ROM measures were 124.1° and 122.2° for telehealth-delivered and in-person groups respectively; and 108.7° and 111.6° at 7-week post-surgery. KOOS-QOL scores were 32.7 and 33.3 at baseline for the respective groups; and 60.9 and 62.9 at week-7. There were no significant differences in between group changes over time for both KF-ROM (mean difference = -2.9°, 95% CI = -7.7 to 1.8; p=0.226) and KOOS-QOL (mean difference = -2.1, 95% CI: -10.0 to 5.9; p=0.611). Chi square analyses revealed no differences between groups meeting the MCIC (Tele = 71%; Clinic = 79%) in KF-ROM (X2 = 0.78, p = 0.377).\u0000 \u0000 \u0000 \u0000 Short term outcomes following TKA are not different between telehealth-delivered and conventional supervised rehabilitation. Telehealth may provide an effective rehabilitation option for patients undergoing TKA.\u0000","PeriodicalId":92070,"journal":{"name":"Journal of clinical exercise physiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141044590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
