FGF-2 enriched nanofiber scaffold for advancing achilles tendon healing: a comparative experimental investigation.

Introduction: Achilles tendon rupture is a common and debilitating injury that significantly impacts mobility and quality of life. Effective treatment options that promote faster and more complete healing are needed. Fibroblast growth factor-2 (FGF-2) has shown potential in enhancing tendon repair.

Effect of intramuscular fat in the thigh muscles on muscle architecture and physical performance in the middle-aged women with knee osteoarthritis.

Background: We investigated intramuscular fat (IMF) in quadriceps femoris (QF) and hamstring muscles in the middle-aged women with knee osteoarthritis (KOA). We also examined the relationship between muscular infiltration of QF and hamstring muscles and muscle architecture and physical performance of the women with KOA.

Methods: In this cross-sectional study, 72 women were included.

Ultrasound imaging of quadriceps muscle in patients with knee osteoarthritis: The test-retest and inter-rater reliability and concurrent validity of echo intensity measurement.

Background: Echo intensity(EI) on ultrasonography images of skeletal muscle reflects muscle composition.

Objectives: The primary aim of the study was to investigate the inter-rater and test-retest reliability of EI using grayscale histogram analysis of the cross-sectional area of quadriceps femoris(QF) muscle in patients with knee osteoarthritis(KOA). The secondary aim of the study was to determine the concurrent validity of the Free Hand Tool(FHT) when compared to Rectangular Marquee Tool(RMT) for calculating the region of interest(ROI) in ImageJ.

Comparison of contact surface areas of metatarsal diaphyseal osteotomies for correction of hallux valgus: Experimental study.

Objective: This study aimed to determine, pre-correction, the potential change in the osteotomy-site bony contact surface area that would occur during standard metatarsal diaphyseal procedures with the Baran-Unal modification of Mau osteotomy and then to compare it, post-correction, with the actual osteotomy-site bony contact surface area changes for a standard degree of deformity correction.

Methods: A total of 30 standard, same sized, biomechanically equivalent, left first metatarsal sawbones were included in this experimental study. They were divided equally into five groups for each of the planned osteotomy techniques: Myerson's modification of Ludloff, Mau, scarf, Offset V, and Baran-Unal modification of Mau osteotomy.

Anatomical axis validation of lower extremity for different deformities: A radiological study.

Aim: The aim of this study was to derive a pure, unbiased, reliable and accurate objective relationship between the local knee axis measurements through a short knee anteroposterior roentgenogram and the lower limb axis measurement through an orthoroentgenogram.

Patients And Methods: Radiographs of 114 patients (114 knees) were evaluated by two independent raters for measurement of lower limb axis on an orthoroentgenogram and the local knee axis on short knee anteroposterior X-ray, which was derived by cropping the orthoroentgenogram by a blinded radiology assistant. The raters measured at two different time-points separated by an interval of 30-day period.

Arthroscopic chronic tennis elbow surgery preserves elbow proprioception.

Study Design: Retrospective cohort study.

Introduction: A new method of accurately assessing the compromised elbow's proprioception was developed for this postsurgical population using information from previous neurophysiologic proprioception studies of healthy elbows.

Hypothesis: This retrospective cohort study investigated the patterns and the degree of proprioceptive impairment and recovery following arthroscopic surgery for chronic lateral epicondylitis.

A new study of hindfoot endoscopy: Foreign body excision from the hindfoot.

Residual foreign bodies are usually observed inside the body after foreign body penetration injuries. However, foreign bodies inside or near the joints are rarely encountered. In the case study included in this report, the case of a foreign body in the posterior ankle region of a 10-year-old child is presented, along with a new study highlighting the technique of its excision with hindfoot endoscopy.

There is No Remarkable Difference Between Pedicle Screw and Hybrid Construct in the Correction of Lenke Type-1 Curves.

Aim: To compare the deformity correction success of segmental pedicle screw and hybrid instrumentation for the treatment of Lenke type-1 adolescent idiopathic scoliosis (AIS) curves.

Material And Methods: Surgically treated Lenke type-1 scoliosis patients were retrospectively evaluated and data of 26 patients treated with hybrid instrumentation were included in the first group. In this group, all patients had been operated with hooks at the thoracic part and transpedicular screws at the lumbar part.

A simple suture-guiding device for minimally invasive Achilles tendon repair.

Background: Our hypothesis is to utilize a simple suture-guiding device for minimally invasive repair of Achilles tendon without any extra cost with a minimal risk of rerupture. The purpose of this study is to investigate the results of our minimally invasive technique for Achilles tendon repair using a simple ovarian clamp for suture guiding.

Materials And Methods: Twenty patients with acute Achilles tendon rupture were treated with minimally invasive repair by an expert orthopaedic surgeon.

[Investigation of radioulnocarpal joint load distribution effects of radial shortening osteotomy for the treatment of Kienböck disease: a biomechanical study].

Objectives: We evaluated the effects of radial shortening osteotomy on the radiolunate joint load distribution.

Materials And Methods: This biomechanical study used standard left wrist models made of solid foam (Sawbones, Malmö, Sweden). The radioulnocarpal joint load distribution was investigated in the normal wrist model and 2 mm and 4 mm radial shortening osteotomy models under 14 kgf and 25 kgf loads when the wrist position was neutral.

Comparison of screw-fixation stabilities of first metatarsal shaft osteotomies: a biomechanical study.

Objectives: Although metatarsal shaft osteotomies have become popular in the surgical treatment of moderate or advanced hallux valgus owing to better reduction and stability, they present fixation problems as the angular correction increases. The purpose of this biomechanical study was to evaluate the effects of widely used metatarsal shaft osteotomies and a newly defined osteotomy modification on the stability of screw fixation at greater angular corrections.

Methods: Upon evaluation of known problems of shaft osteotomies, a new osteotomy type was designed that might provide an adequate contact area while allowing a greater angular correction, increased stability, and safer osteosynthesis.
