Diffuse-type giant cell tumor: Pigmented villonodular synovitis of patellar fat pad.

Pigmented villonodular synovitis (PVNS) is a rare, relatively benign intra-articular lesion characterized by slowly progressing proliferation of the synovial tissue. It is most commonly observed in the knee joint. Localized and diffuse types are two types of PVNS depending on the synovial involvement.

The relationship between extremity fractures and visual impairment in childhood: A case-control study.

Background: Fractures are common extremity injuries in pediatric orthopedic practice. The aim of this study is to determine the relationship between pediatric extremity fractures and visual impairments.

Methods: Thirty pediatric patients who were admitted to the emergency and orthopedics and traumatology clinic due to an extremity fracture after a fall were included in the study.

Readability and quality levels of websites that contain written information about anterior cruciate ligament injury: A survey of Turkish websites.

Objective: This study aimed to evaluate the contents and readability levels of informative texts about anterior cruciate ligament (ACL) on Turkish websites.

Methods: In this cross-sectional study, online searches were performed using the Google, Yandex, and Yahoo search engines on 16, 17, and 18 November 2020, respectively. In these three search engines, 'anterior cruciate ligament', 'anterior cruciate ligament surgery', 'ACL', and 'ACL surgery' were entered in Turkish.

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.

The effect of astaxanthine on ischemia-reperfusion injury in a rat model.

Background: We aimed to compare biochemical and histopathological findings of astaxanthin's potential effects on oxidative stress in ischemia/reperfusion damage (I/R).

Methods: Thirty-two rats were randomly divided into four groups: control group; I/R group; I/R + treatment group; drug group. Astaxanthin was orally administered to groups C and D for 14 days.

Effects of adipose tissue-derived stromal vascular fraction on osteochondral defects treated by hyaluronic acid-based scaffold: An experimental study.

Objectives: This study aims to evaluate the effect of adipose-derived stromal vascular fraction (SVF) on osteochondral defects treated by hyaluronic acid (HA)-based scaffold in a rabbit model.

Materials And Methods: Eighteen white New Zealand rabbits were randomly grouped into the experimental group (n=9) and control group (n=9). In all groups, osteochondral defects were induced on the weight-bearing surfaces of the right femoral medial condyles, and a HA-based scaffold was applied to the defect area with microfractures (MFs).

Tranexamic acid has positive effect in early period of tendon healing by stimulating the tumor necrosis factor-alpha and matrix metalloproteinase-3 expression levels.

Objectives: This study aims to evaluate the effect of tranexamic acid (TXA) application in tendon healing by using its immunohistochemical effects on tumor necrosis factor-alpha (TNF-α), matrix metalloproteinase-3 (MMP-3), and transforming growth factor-beta (TGF-β) expression; and to identify if TNF-α, MMP-3, and TGF-β can be used to monitor and evaluate tendon healing or not in tenotomized rat Achilles tendons.

Materials And Methods: Twelve male Wistar-Albino rats (age 6-7-month-old; weighing 300-350 g) were used in this retrospective study conducted between November 2016 and May 2017. The rats were divided into two groups with similar weights.

Does methylene blue reduce adhesion during the healing process after tendon repair?

Objectives: This study aims to biomechanically and histopathologically investigate the effects of methylene blue (MB) on preventing postoperative adhesion in chickens undergoing full- thickness flexor tendon incision.

Materials And Methods: This study was performed between June 2017 and June 2018 on Hubbard JA 57 type chickens (age, 6 months; weight, 2.2±0.

The effect of pentoxifylline on Achilles tendon healing in tenotomized rabbits.

Objectives: This study aims to evaluate the potential effects of pentoxifylline (PTX) on tendon healing and to compare the histopathological and biomechanical findings of the healed tendon among the groups.

Materials And Methods: The study was conducted on 36 male New Zealand albino rabbits (age, 3 months; weighing, 2.5±0.

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.
