    (Cureus INC, 2019-11-04) Karaca, Sinan; Erdem, Mehmet Nuri; Öztermeli, Ahmet; Bal, Emre; Göğüş, Abdullah; Hamzaoğlu, Azmi
    Purpose The aim of this retrospective study was to investigate the effectiveness of medial unicompartmental knee arthroplasty (UKA) by showing the results of the radiological and clinical outcomes of the patients. Materials and methods Seventy-two knees of 54 patients who underwent UKA between September 2005 and March 2011 for medial knee arthritis with a minimum follow-up of six months were evaluated. Range of motion (ROM), Hospital for Special Surgery (HSS) knee score, Knee Society Score (KSS), and Oxford Knee Score (OKS) were investigated both preoperatively and postoperatively. On the other hand, Oxford radiographic evaluation criteria were used to evaluate prostheses radiologically at the final follow-up. Results The average age was 53.4 years (47 to 79 years). The average follow-up time was 39.8 months (8 to 72 months). There was a significant difference between preoperative and postoperative ROM, HSS, and OKS (p<0.05). Radiologically, there was no sign of arthritis on the unoperated side of the knee or failure of prosthesis detected. Before the operation, the average clinical KSS was 63.2 and improved to 91.4 after the operation. In addition, the average functional KSS was 54.9 before the operation and improved to 86.5 after the operation. The average knee flexion degree was 109.1 before the operation and there was an improvement to 123.6 degrees after the operation. Before the operation, the average HSS score was 67.5 (range, 52 to 75) and improved to 89.9 (range, 85 to 100) at the final control examination. Conclusion This study supports the use of Oxford Phase 3 UKA, which has excellent clinical and radiological results in patients with medial knee arthritis.

    A Comparison of high viscosity and low viscosity bone cement vertebroplasty for severe osteoporotic vertebral compression fractures
    (Galenos, 2019-01) Karaca, Sinan; Öztermeli, Ahmet; Akpolat, Ahmet Onur; Erdem, Mehmet Nuri; Aydoğan, Mehmet
    Introduction: Our aim in this clinical trial was to compare the safety and efficacy of highviscosity cement (HVC) with low-viscosity cement (LVC) for the treatment of osteoporotic vertebrae fractures in terms of pain, functional capacity and cement leakage in the percutaneous vertebroplasty procedure (PVP). Methods: From March 2013 to February 2015, 76 patients with vertebrae compression fracture who were admitted into hospital and treated with PVP were reviewed. Pre- and postoperative clinical characteristics of each patient were obtained by using The Visual Analog Scale (VAS) score to evaluate back pain, Oswestry Disability Index (ODI) as a functional assessment. Cement leakage,injected cement volume and the complications assessed due to medical records. Results: VAS and ODI scores improved (P<0.05) significantly in the two groups postoperatively on the other hand there was no significant change between two groups (P>0.05).Paravertebral cement leakage was significantly higher in the LVC group (P<0.05). Pulmonary cement embolism was also significantly higher in LVC group (P<0.05). Conclusion: HVC had lower complication rates with similar clinical results in the comparison with LVC.

    Patient-centered outcomes of vertebroplasty via questionnaire
    (Galenos, 2019) Karaca, Sinan; Erdem, Mehmet Nuri
    Purpose: Our aim was to evaluate patient centred outcomes of patients with compression fractures treated by vertebroplasty. Methods: Patients with compression fractures treated by vertebroplasty procedure between 2013- 2016 was examined with a 3-question through telephone call. Results: Fifty-two patients completed the telephone satisfaction survey. Of these, 92.5 % of answerers said the procedure was acceptable, 86.5% had full or partial pain remission and 78.8 % would have the procedure again. Conclusions: The use of vertebroplasty is supported by randomized trials in osteoporotic and malignant compression fractures. To the results of our study, patients believe vertebroplasty is a tolerable procedure that produces full or partial pain remission and would try the same procedure again if needed.
