Objective: The aim of this study was to evaluate the results of cement and kirschner wire augmentation in the management of bone defects in primary TKA. Methods: Twenty-four patients (10 male, 14 female; mean age: 66 years) with uncontained unilateral medial tibial articular bone defect who underwent TKA between 2010 and 2014 were included in this study. The average follow up time was 33.7 months. Patients were divided to two groups according to the size of the bone defect (Group 1: 20 mm). The tibial defect was reconstructed by using cement and K-wires. We used posterior stabilized prosthesis with no tibial stem extension. Results: The preoperative and postoperative lower extremity mechanical axis in Group I was in a mean varus of 15° and mean varus of 3°, respectively (p

[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
