Publication Metadata only Comparison of 3 Cell-Free Matrix Scaffolds Used to Treat Osteochondral Lesions in a Rabbit Model.(2022-03-30T00:00:00Z) Ucan, Vahdet; Pulatkan, Anil; Yilmaz, Bengi; Tahmasebifar, Aydin; Tok, Olgu Enis; Tuncay, Ibrahim; Elmali, Nurzat; Ozturk, Burak Yagmur; Uzer, GÖKÇER; UÇAN, VAHDET; TUNCAY, İBRAHİM; UZER, GÖKÇERPublication Open Access Unicompartmental knee arthroplasty combined with high tibial osteotomy in anteromedial osteoarthritis: A case report(2021-01-01T00:00:00Z) UÇAN, VAHDET; Pulatkan, Anil; TUNCAY, İBRAHİM; UÇAN, VAHDET; TUNCAY, İBRAHİMIntroduction and importance: Anteromedial osteoarthritis (AMOA) is a common knee pathology. However, the best treatment of AMOA remains unclear. Unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) are surgical options for AMOA patients who do not benefit from conservative treatment. We aimed to show an unusual treatment option where UKA and HTO are performed simultaneously. Case presentation: We present a 52-year-old man with AMOA secondary to spontaneous osteonecrosis of the knee (SONK) and metaphyseal tibial varus malalignment, who was successfully treated with a combined UKA and HTO. His functional scores were excellent at the 5-year follow-up. Clinical discussion: Advanced SONK that causes AMOA can be treated with osteochondral autograft transplantation (OAT), HTO, UKA, or total knee arthroplasty (TKA). Although good results have been reported selecting appropriate patients for all of these methods, the best treatment method remains unclear. Conclusion: Although HTO and UKA are alternative treatments for AMOA, successful results can be obtained using both in individual cases.Publication Metadata only Are the functional outcomes really inferior following unicondylar knee arthroplasty in patients with partial-thickness cartilage loss?(2021-11-01T00:00:00Z) Pulatkan, Anil; YILDIZ, FATİH; UÇAN, VAHDET; ELMALI, NURZAT; TUNCAY, İBRAHİM; YILDIZ, FATİH; UÇAN, VAHDET; ELMALI, NURZAT; TUNCAY, İBRAHİMObjective: The main indication for medial Unicondylar Knee Arthroplasty (UKA) is Full-Thickness Cartilage Loss (FTCL) in the isolated medial compartment of the knee. However, controversial outcomes were reported in patients with Partial-Thickness Cartilage Loss (PTCL). The aim of this study is to compare PTCL and FTCL based on intraoperative findings in medial UKA in terms of functional outcomes and complication rates requiring reoperation and revision.Publication Open Access A Novel External Fixator Designed for a More Comfortable and Secure Hip Arthroscopy(2022-01-01T00:00:00Z) Pulatkan, Anil; UÇAN, VAHDET; YILDIZ, FATİH; TUNCAY, İBRAHİM; UÇAN, VAHDET; YILDIZ, FATİH; TUNCAY, İBRAHİMObjective: To evaluate the functional results of a novel external fixator (EF) designed for joint distraction and prevention of traction table-related hip arthroscopy complications Methods: After obtaining promising results in a cadaveric study, 21 hips of 20 patients underwent EF-assisted arthroscopic hip surgeries for femoroacetabular impingement (FAI) and/or labral tear treatments. Patients were operated on a standard operating table in the supine position. A novel EF was used to distract the joint for central hip arthroscopy. The time needed for EF application and joint distraction and the amount of joint distraction were recorded. Preoperative functional scores were retrospectively compared to the postoperative 5-year follow-up results using the Harris Hip and Western Ontario and McMaster Universities Index scores. Results: All patients underwent peripheral and central arthroscopy. The mean time for EF application and joint distraction was 19 min (range: 8-21). The mean amount of joint distraction was 13.2 mm (range: 12-18). None of the arthroscopic procedures had to be converted to open surgery. Functional results of all patients were improved at the 5-year follow-up (p<0.01). Only one patient required hip arthroscopy revision due to residual FAI. No other major or minor complication was found that is related to the EF or arthroscopy itself. Conclusion: Mid-term outcomes following EF-assisted hip arthroscopy demonstrate significant improvement in the functional outcomes without traction table-related complications. EF can be used as an alternative to traction table to maintain adequate hip distraction in arthroscopic hip surgery. In addition to the rotation, a novel designed EF allows hip joint flexion during distraction contrary to traction table.
