Overlapping repair and epitenon healing are more stable biomechanically than side to side repair and endotenon healing in achilles tendon lengthening with Z plasty.

Background: The current study aimed to compare biomechanical stability and healing process of side-to-side repair with overlapping repair after Achilles tendon lengthening with Z-plasty.

Methods: In our study, 22 Sprague Dawley male rats were used. Side-to-side repairs were classified as group 1 and overlapping repairs as group 2.

Tibiofemoral subluxation in the coronal plane does not affect WOMAC and KOOS after total knee arthroplasty.

Purpose: To investigate the effect of preoperative coronal tibiofemoral subluxation (CTFS) on functional outcome, prosthesis type, insert thickness and revision rates in patients who underwent total knee arthroplasty (TKA).

Methods: A total of 224 knees of 186 patients were included. Patients were divided into two groups as either with (Group 1, 114 knees of 86 patients) or without (Group 2, 124 knees of 100 patients) coronal lateral tibiofemoral subluxation.

Painful transient edema in the tibial diaphysis: the challenges and the essence of biopsy in treatment.

Background: Some patients experience a non-traumatic pain in the tibial diaphysis similar to that in the clinical and radiological findings of a tumor, an infection or a stress fracture and cannot be definitively diagnosed even after biopsy. In this study, our aim was to exhibit the challenges in the diagnosis of this patient group and to evaluate this type of patients with a limited population in the literature.

Methods: Eighteen extremities of 16 patients, whose complaints of non-traumatic pain in the tibial diaphysis were evaluated by our tumor council and T2-weighted MR scans of the medullary bone had shown hyperintense signal changes or tumor-like appearances, were evaluated with histological, radiological, and clinical results.

Tibial tubercle-trochlear groove distance and angle are higher in children with patellar instability.

Purpose: The purpose of this study was to assess the variations in tibial tubercle-trochlear groove distance and angle as a function of age and gender in a population of children without patellar instability (PI) compared with those with PI.

Methods: A retrospective review of 869 children's knee MRIs, ages 5 to 15 years, were evaluated using a control group (792 children) without evidence of PI and a group with PI (77 children). Tibial tubercle-trochlear groove distance (TT-TGd) and angle (TT-TGa) were measured twice by two readers to assess intra- and inter-observer reliability and compared between PI and control groups.
