RAPID REHABILITATION ARTHROPLASTY PROTOCOL IN SAUDI ARABIA : REDUCING HOSPITAL STAY

Background: Fewstudies havefocused on patient characteristics that influence lengthof stay in fast-track total hip (THR) and kneearthroplasty (TKR). The aim of this retrospective studywas to identify patient characteristics associated withlength of stay and patient satisfaction after total hip and kneereplacement surgery. Patients and Methods: Between January 2023 toJune 2023,62 TKR patientswith a mean age of 67.6±11.8years and 12 THR with a mean age of 53.8±17.0wereadmitted at ourspecialized fast-track joint replacement unit. A single fellowship-trained surgeon operated on all patients.We did interviews with the patients before the operation and 6 weeks after surgery to collect pre and post-operative Oxford knee scores for TKRs and pre and post-operation Oxford hip scores for THRs. Results: A total of 62 TKR patients and 12 THR patients enrolled in our study. The mean age of TKR patients was 67.6±11.8years, and 44 subjects (71%) were female. The mean age of THR patients was 53.8 years±17.0, and 8 subjects (66.7%) were male. Mean of BMI was reported as 33.9±6.1 in TKR patients and 30.9±6.1 in THR patients. The Mean of ASA was 2.2±0.6 in TKR patients and 1.9±0.5 in THR patients. Length of stay in hospital was documented as 3.9±0.7 in TKR patients and 4.3±0.6 in THR patients.Most patients of have osteoarthritis, while rheumatoid arthritis was reported in TKR (n=3, 4.8%) and THR (n=1, 8.3%) patients. A significant length of stay was reported with increasing BMI and ASA score in TKR and THR patients. In Conclusion: The most common diagnosis for surgery was osteoarthritis, which usually affected womens right sides. Annual increases in the number of surgeries have been made, and Oxford ratings indicate that they have a very high success rate. The characteristics linked with a prolonged duration of stay after total hip or knee arthroplasty are significantly influenced by the case mix, particularly the BMI and ASA before surgery.
