Publication Open Access Reply to Letter to Editor: Safety of one-stage bilateral total knee arthroplasty-one-surgeon sequential vs. two surgeons simultaneous: a randomized controlled study(2020-08-01T00:00:00Z) Gungoren, Nurdan; UZER, GÖKÇER; ALIYEV, ORKHAN; YILDIZ, FATİH; ELMALI, NURZAT; TUNCAY, İBRAHİM; UZER, GÖKÇER; ALIYEV, ORKHAN; YILDIZ, FATİH; GÜNGÖREN, NURDAN; ELMALI, NURZAT; TUNCAY, İBRAHİMPublication Open Access Use of cement combined grafting in upper and lower extremity benign bone tumors(2020-01-01T00:00:00Z) Pulatkan, Anil; Ucan, Vandet; TOKDEMİR, SEVİL; ELMALI, NURZAT; GÜRKAN, Volkan; UÇAN, VAHDET; TOKDEMİR, SEVİL; ELMALI, NURZAT; GÜRKAN, VOLKANObjectives: This study aims to investigate the effectivity of cement combined demineralized bone matrix (DBM) treatment on new bone formation in the cortical window as well as to evaluate the effect of new bone formation on functional outcomes. Patients and methods: Thirty-two benign bone tumor patients (15 males, 17 females; median age 38 years; range, 12 to 68 years), who were treated with cement combined DBM between February 2010 and December 2014, were evaluated retrospectively. Patient characteristics were recorded as age, gender, tumor localization, histological diagnosis, Enneking stage, tumor size, size of the cortical window, usage of prophylactic fixation, time to return to work, Musculoskeletal Tumor Society (MSTS) functional score, tumor relapse, and new bone formation on the cortical window in the computed tomography scans after one year of surgery. Results: Median tumor volume was 17.2 cm 3 (range, 2.8 to 139.6 cm 3 ), median area of the cortical window was 8.3 cm 2 (range, 1.6 to 28.4 cm 2 ), and median postoperative one-year MSTS score was 84.5 (range, 66 to 97). MSTS scores were significantly worse with the usage of prophylactic fixation (p<0.001). There was a statistically significant difference between the usage of prophylactic fixation and cortical window size (p=0.013). There was a low-level negative correlation in terms of age and bone formation on the cortical window (p=0.046, r= -0.356) and mid -level negative correlation between cortical window size and functional scores (p=0.001, r= -0.577). Conclusion: Application of cement combined with DBM procedure is an effective, alternative, and biological treatment in bone tumors that provides immediate stability and stimulates new bone formation on the cortical window.Publication Open Access Effect of microfracture and autologous-conditioned plasma application in the focal full-thickness chondral defect of the knee: an experimental study on rabbits(2015-07-16) KARAKAPLAN, MUSTAFA; Sahin, Nurhan; MIREL, Efe; Ergen, Emre; ELMALI, Candan; ELMALI, NURZAT; ŞAHİN, NURHANPurpose: The aim of the present study was to evaluate the effect of microfracture and intraarticular autologous conditioned plasma (ACP) injection on cartilage regeneration in a focal full-thickness chondral defect model created in the knee joint. Methods: Full-thickness chondral defects of 3 × 6 mm(2) were surgically created in right medial femoral condyles (MFC) of New Zealand rabbits, and the rabbits were then divided into three groups according to treatment: Group 1 received only microfracture (mfx), Group 2 received mfx plus intraarticular ACP, and Group 3 received mfx; the defect was covered by the periosteum, and then, ACP was applied subperiosteally and intraarticularly. Twelve weeks after injection, the animals were sacrificed and the femoral condyles were evaluated macroscopically and histologically by hematoxylin-eosin staining. Then, histological sections were scored using the International Cartilage Repair Society (ICRS) visual histological scale. Results: Findings showed that in both mfx/ACP-treated groups, the defects were filled regularly and smoothly, the defects had a greater fill and good integration into the surrounding host tissue, and the repair matrix had more hyaline-like character. On the other hand, defects were filled with an irregular, fibrous cartilage in the mfx-treated group. Histological scores in Group 2 and Group 3 were better compared to Group 1. Conclusion: In the present study, we were able to demonstrate a beneficial effect of intraarticular administration of ACP as a coadjuvant of microfractures in order to regenerate hyaline-like cartilage in full-thickness chondral lesions in a rabbit model.Publication Open Access Does the anteromedial portal provide clinical superiority compared to the transtibial portal in anterior cruciate ligament reconstruction in nonprofessional athletes in short-term follow-up?(2015-01-01) TASDEMIR, Zeki; GULABI, Deniz; SAGLAM, Fevzi; OZAL, Safiye Tokgoz; Elmali, NURZAT; ELMALI, NURZATObjective: Two drilling techniques of the femoral tunnel are commonly used in anterior cruciate ligament (ACL) reconstruction: through the transtibial (TT) portal or through the anteromedial (AM) portal. The aim of the present study is to investigate the radiological and clinical outcomes of arthroscopic single-bundle ACL reconstruction using AM and TT portal techniques for drilling the femoral tunnel in nonprofessional athletes. Methods: A retrospective review was made of 44 nonprofessional athletes undergoing ACL reconstruction using AM and TT techniques between 2011-2013. The femoral tunnel clock position on axial magnetic resonance imaging (MRI) and the anterior-posterior position of the tibial tunnel on sagittal-cut MRI scan were measured. Radiological femoral tunnel and tibial tunnel anterior-posterior inclination angles were assessed. At final follow-up, the Lachman test and pivot-shift test were used in the evaluation of the anterior-posterior stability of the knee and the rotational stability of the knee. For clinical and functional evaluation, the modified Cincinnati knee grading system, Lysholm knee scoring scale, and International Knee Documentation Committee (IKDC) form were used. Results: No statistically significant difference was determined between the groups in terms of patient age, follow-up period, gender, and affected side distribution. There were 6 outliers in the TT group due to the clock face position. The mean femoral tunnel inclination angle was 31.07°±8.44° in the AM group and 19.02°±8.93° in the TT group. The tibial tunnel inclination angle was 21.08°±5.42° in the TT group and 16.58°±7.02° in the AM group. A statistically significant difference was determined between the 2 groups. No statistically significant difference was observed between the 2 groups in terms of Lachman test, pivot-shift test, Lysholm score, IKDC score, and modified Cincinnati score results. Conclusion: The AM technique has no clinical superiority compared to the TT technique in ACL reconstruction in nonprofessional athletes.Publication Open Access Cartilage repair strategies in the knee: A survey of Turkish surgeons(2016-10-01) ELMALI, NURZAT; Tandogan, Reha; Demirel, Murat; BOZKURT, MURAT; Beyzadeoglu, Tahsin; ELMALI, NURZATObjectives: The purpose of this study was to analyze the trends in cartilage repair strategies among Turkish orthopedic surgeons for isolated focal (osteo)chondral lesions of the knee joint. Materials and methods: A web-based survey of 21 questions consisting of surgical indications, techniques and time to return to sports was developed to investigate the preferences of members of the TOTBID and the TUSYAD. Results: A total of 147 surgeons answered the questionnaire.70% of the respondents were TUSYAD members. 82% of respondents had at least five years experience in arthroscopy. Half of the surgeons indicated that patient age of 50 was the upper limit for cartilage repair. Irrespective of activity level, microfracture (60e67%) was the most frequently used technique for lesions smaller 2.5 cm2 . In lesions larger than 4 cm2 , MACI was the most commonly advocated procedure (67%). In patients with high activity levels, mosaicplasty was the first choice (69%) for lesions between 2.5 and 4 cm2 in size, followed by MACI (27%). Conclusion: Patient age, activity level, BMI and lesion size were important determinants for the choice of treatment of isolated chondral lesions in the knee. These results reflect the choices of experienced knee surgeons in the country. Although not widely performed in Turkey and has limited reimbursement by the health care system, the first choice for defects over 4 cm2 was second generation ACI. Third party payers & health reimbursement authorities should take into account that large defects require methods which are relatively expensive and need high technology.

Herein, we present a 59-year-old male case with a three-month history of an irreducible locked bilateral posterior dislocation of the shoulders with an associated large impression fracture on the anteromedial aspect of both humeral heads after a grand mal type epileptic seizure. Plain X-ray and computed tomograph revealed a defect on the right side more than 40% of the articular surface, and on the left side, 30%. He was treated with a one-stage operation with a reconstruction of femoral head osteochondral allograft on the right side and transfer of the osteotomized tuberculum minus with its attached subscapularis tendon into the defect (modified McLaughlin technique) on the left side. At 14 months during follow-up, the patient was pain-free with stable shoulder joints and satisfactory functionality.Publication Open Access Surgical treatment of distal tibia fractures: open versus MIPO(2016-01-01) GULABI, Deniz; BEKLER, Halil Ibrahim; SAGLAM, Fevzi; TASDEMIR, Zeki; CECEN, Gultekin Sitki; Elmali, NURZAT; ELMALI, NURZATBACKGROUND: Treatment of the distal tibial fractures are challenging due to the limited soft tissue, subcutaneous location and poor vascularity. In this control-matched study, it was aimed to compare the traditional open reduction and internal fixation with minimal invasive plating (MIPO). We hypothesized that superior results may be achieved with MIPO technique. METHODS: 22 patients treated with traditional open reduction and internal fixation were matched with 22 patients treated with closed reduction and MIPO on the basis of age (±3), gender, and fracture pattern (AO classification). Evaluation was assed according to the wound problems, the American Orthopaedic Foot and Ankle surgery (AOFAS) scoring, radiological union, malunion, delayed union, hospitalisation time, time from injury to surgery, and operation time. RESULTS: There was no significant difference in the distribution of AO/OTA classification, age, gender, AOFAS score, time from injury to operation, follow-up, bone union time, delayed union, malunion and infection (p>0.05). The operation time was significantly longer in the open group than in the MIPO group: 69.59±7.21 min. for the ORIF, and 61.14±5.61 for the MIPO group (p<0.01).The hospitalisation time was significantly longer in the open group than in the MIPO group: 7.64±4.71 days for the MIPO, and 10.18±4.32 days for the ORIF group (p<0.05). CONCLUSION: MIPO technique can be beneficial for the treatment of distal tibia AO/OTA A and B type fractures with reduced hospital stay, cost-effectiveness, and infection rate.
