To evaluate the short-term results of the rehabilitation programme with two different supervision on balance and functionality after simultaneously bilateral total knee arthroplasty (SBTKA) in patients with osteoarthritis and to compare the results with those of healthy individuals.This study was a single-blind randomized controlled study. Two exercise groups who underwent primary bilateral total knee arthroplasty (Group 1, n = 20 and Group 2, n = 20) and a control group of healthy individuals (Group 3, n = 20) included in the study. Group 1 applied exercise programme with intensive supervision of the physiotherapist for a period of 1 month (2 days/1 week). Group 2 performed exercise programme under the control of same physiotherapist twice monthly (1 day/2 weeks), and the patients were checked every week by telephone interview. Pre-operative and post-operative blind evaluations were made at first and second month. Static balance with single leg stance test, dynamic balance with timed get upgo (TGUG), functionality with walking cadence, stair climbing test (SCT) and Western Ontario McMaster Universities (WOMAC) index were assessed.Group 1 improved statistically significantly better in terms of SLST (p = 0.0 (right), p = 0.0 (left)) and WOMAC function (p = 0.0) at first month, and SLST (p = 0.0), TGUG (p = 0.0), SCT (p = 0.0), WOMAC pain (p = 0.0), stiffness (p = 0.0) and function (p = 0.0) at second month. In Group 1, TGUG, walking cadence, SCT, WOMAC pain, stiffness and function results reached the levels of healthy individuals at second month, and SLST was better for two legs as compared to healthy individuals. In Group 2, cadence results were similar to healthy individuals at second month.The osteoarthritis patients who had the applied rehabilitation programme after SBTKA with intensive supervision of the physiotherapist for 1 month have obtained more improvements in balance and functional parameters, and it was demonstrated that their performances approached the healthy control group values. As a clinical relevance of our study, intensive supervision of rehabilitation programme should be provided to the patients after SBTKA surgery to accomplish early balance and functional improvements.

[Purpose] The aims of our study were, 1. to assess pain, limitation of movement ability, and functionality in osteoarthritis patients scheduled to undergo total knee arthroplasty, 2. to determine if pain (Group 1) or function loss (Group 2) has a greater influence on the decision of patients to have surgery, and 3. to compare results between Group 1 and Group 2. [Subject and Methods] Fifty-five osteoarthritis patients classified as grades 3 and 4 according to the Kellgren-Lawrence system of classification were evaluated for preoperative pain intensity with the Visual Analogue Scale, knee flexion/extension range of movement with a clinical goniometer, and function with the Western Ontario and McMaster Universities Osteoarthritis Index. Patients were examined to reveal their reasons regarding the decision to undergo total knee arthroplasty (pain or function loss). [Results] The Visual Analog Scale scores at rest and during activity were 5.62 and 7.42, the knee flexion range of movement and extension limitation were 93.17° and −7.04°, and the Western Ontario and McMaster Universities Osteoarthritis Index value was 82.09. Regarding the decision to undergo surgery, 47.3% (n=26) of the knees were in Group 1, and 52.7% were in Group 2; the two groups were not significantly different. There were also no significant differences between the groups in Visual Analog Scale score during activity, the Western Ontario and McMaster Universities Osteoarthritis Index value, and knee flexion range of movement and extension limitation. The only statistically significant difference was found in the Visual Analog Scale score at rest in Group 1, which was significantly higher than that in Group 2. [Conclusion] Our results showed that osteoarthritis patients decided to undergo surgery only if all of the parameters were impaired significantly. Both pain and function loss have a similar impact on a patient’s decision to undergo surgery. We observed no significant difference in clinical and self-reported outcomes between patients who decided to undergo surgery due to pain or function loss.

Objective: The purpose of this study was to investigate the mid-term and long-term effects of the acetabular roof ring (ARR) and Burch-Schneider anti-protrusio cage (BSAPC) in acetabular revision for patients with acetabular bone deficiency and acetabular component loosening. Methods: Between 1988 and 2007, ARR revisions were performed in 51 patients (25 women; average age: 46.9 years) and BSAPC in 18 patients (16 women; average age: 62.1 years). Grafts were used in all revisions. The patients were evaluated retrospectively. The bone defects were classified according to the classification of the American Academy of Orthopaedic Surgeons (AAOS). Harris Hip Score (HHS) was used for clinical evaluation. Radiolucent lines, implant sizes, osseointegration, and heterotopic ossification in the 3 regions defined by DeLee and Charnley were evaluated radiologically. Results: The success rate of ARR revisions after an average follow-up of 8.93±4.10 years (range: 4–23 years) was 87.9%, and the cumulative survival rate at year 10 postoperatively was 91%. Average HHS score increased to 83.70±8.98 postoperatively, from 40.10±2.49 preoperatively (p
