title: The effects of short-term preoperative physical therapy and education on early functional recovery of patients younger than 70 undergoing total hip arthroplasty.
abstract: OBJECTIVE
  Hip arthroplasty is a routine operation which relieves pain in patients with osteoarthritis. The role of physical therapy after hip arthroplasty was recognized, but the importance of preoperative physical therapy and education is still to be judged. The aim of this paper was to investigate the effect of short-term preoperative program of education and physical therapy on patients' early functional recovery immediately after total hip arthroplasty (THA).
  
  
  METHODS
  This prospective study included 45 patients with hip osteoarthritis scheduled to undergo primary THA and admitted to the Department of Orthopedics of Military Medical Academy. They were randomized into 2 groups: study and control one (with and without preoperative education and physical therapy). Preoperative education was conducted through conversation (1 appointment with physiatrist) and brochure. The study group was instructed to perform exercises and basic activities from the postoperative rehabilitation program (2 practical classes with physiotherapist). Effects were measured with questionnaires (Harris, Oxford and Japanese Orthopaedic Association (JOA) hip scores), range of motion and visual analog scale of pain. Marks showing ability to perform basic activities and endurance were from 0 (did not perform activity) to 5 (independent and secure). Analyses examined differences between the groups over the preoperative and immediate postoperative periods and 15 months after the operation.
  
  
  RESULTS
  There were no differences between the groups at discharge according to pain, range of motion, Harris hip score and JOA hip score. Oxford hip score did not differ between the groups 15 months after the operation. The groups started to walk at the same time, but the study group walked up and down stairs (3.7+/-1.66 vs 5.37+/-1.46, p< or =0.002), used toilet (2.3+/-0.92 vs 3.2+/-1.24, p< or =0.02) and chair (2.2+/-1.01 vs 3.25+/-1.21, p< or =0.006) significantly earlier than the control group. On the third day after the operation the study group was significantly more independent than the control one while performing any basic activities (changing position in bed from supine to side lying, from supine to sitting on the edge of the bed, from sitting to standing, from standing to lying in the bad, standing, walking, using toilet and chair). At discharge the patients from the control group still needed the therapist help for walking up and down stairs (3+/-1.26), while the patients from the study group performed there activities independently (4.85+/-0.37) (p< or =0.000). Endurance while walking was significantly better in the study group than in the control one. The length of hospital stay after the operation was similar for both groups, but the patients from the study group needed significantly less classes with the therapist (5.2+/-2.35 vs 6.85+/-1.14, p< or =0.02) during hospital stay.
  
  
  CONCLUSIONS
  The short-term preoperative program of education with the elements of physical therapy accelerated early functional recovery of patients (younger than 70) immediately after THA and we recommend it for routine use.
