Investigating the magnetic resonance imaging cross-section area that best correlates with intraoperative hamstring autograft size.

Objective: This study aimed to find out the level of the gracilis and semitendinosus tendons that would provide the closest information about the size of the quadruple-stranded hamstring autograft using magnetic resonance images before anterior cruciate ligament reconstruction.

Methods: Ninety-six patients (44 males, 52 females) who underwent anterior cruciate ligament reconstruction with quadruple hamstring tendon autografts between January 2015 and March 2020 were retrospectively analyzed. The cross-sectional areas of the gracilis and the semitendinosus tendons at 6 different levels (pes anserinus insertion site, tibial tuberosity, fibular head, tibial plateau, and the proximal insertion sites of the anterior cruciate ligament and the medial collateral ligament were measured on the magnetic resonance images.

Anatomical Factors Which Influence the Formation of Peroneal Tendon Tears: A Retrospective Comparative Study.

This study aims to investigate the anatomical factors that are effective in the formation of peroneal tendon tears comparing with the control group. The patients with ankle magnetic resonance imaging (MRI) due to pain on the lateral side of the ankle were retrospectively analyzed using the clinical archive between July 2015 and January 2020. Peroneal tendon tears, peroneal tubercle type and size, presence of peroneal quartus, presence and type of retromalleolar groove, retromalleolar groove area, lateral malleolus type, presence of os peroneum, peroneus brevis-lateral malleolus distance (PBLMD), and accompanying pathologies in coronal, axial, and sagittal planes MRI were evaluated.

Effects of Cyanoacrylate in Rabbits with Induced Achilles Tendon Rupture.

BACKGROUND In this study, we aimed to investigate the effects of N-butyl-2-cyanoacrylate (cyanoacrylate) on the biomechanical and histopathological aspects of tendon healing in a rabbit model of Achilles tendon injury. MATERIAL AND METHODS In total, 36 rabbits were randomized to experimental (cyanoacrylate) and control groups (n=36 tendons in each group). A simple suture was used in the control group and a simple suture plus cyanoacrylate was used in the experimental group.

Evaluation of the age and gender related changes in the Blumensaat line.

Purpose: The position of the patella according to the femur is very important in the evaluation of patella-femoral joint disorders. In 1938, Blumensaat (BS) described the BS line to evaluate the patella femoral congruence. This method is still valuable in clinical use.

Effects of tranexamic acid on the recovery of osteochondral defects treated by microfracture and acellular matrix scaffold: an experimental study.

Background: Microfracture and scaffold application in the treatment of osteochondral defects is still one of the most frequently used methods in the clinic. The most important step in this treatment method is the stabilization of fibrin clot. Tranexamic acid (TA) is an antifibrinolytic agent commonly used in orthopedic surgery in recent years.

Asymmetric bilateral hip dislocations and unilateral femoral head fracture: A CASE report.

Hip is a stabilized joint due to the surrounding ligaments, and muscles, which can dislocate as a result of high energy trauma, high-level falls, and motor vehicle accidents. Traumatic hip dislocations can either be isolated or simultaneously with acetabular and proximal femur fractures. At the same time injury of sciatic, femoral or obturator nerves can be seen.

Ultrasound-guided femoral and sciatic nerve blocks combined with sedoanalgesia versus spinal anesthesia in total knee arthroplasty.

Background: Although regional anesthesia is the first choice for patients undergoing total knee arthroplasty (TKA), it may not be effective and the risk of complications is greater in patients who are obese or who have spinal deformities. We compared the success of ultrasound-guided femoral and sciatic nerve blocks with sedoanalgesia versus spinal anesthesia in unilateral TKA patients in whom spinal anesthesia was difficult.

Methods: We enrolled 30 patients; 15 for whom spinal anesthesia was expected to be difficult were classified as the block group, and 15 received spinal anesthesia.

Efficacy of moxifloxacin compared to teicoplanin in the treatment of implant-related chronic osteomyelitis in rats.

Treatment of implant-related chronic osteomyelitis is often difficult and usually consists of implant removal, extensive surgical debridement, and prolonged antibiotic use. This study was performed to assess the efficacy of moxifloxacin compared to a glycopeptide, teicoplanin in chronic implant-related methicillin-sensitive Staphylococcus aureus (MSSA) osteomyelitis. The left femoral medullar cavities of 60 Wistar male rats were contaminated with 100 µl of 10(8) cfu/ml methicillin-sensitive S.
