Correlation between Intensity of Pain and Disability Due to Intra-articular Lesions in Patients with Femoroacetabular Impingement Syndrome.

 To correlate radiographic alterations and lesions in intra-articular structures of the acetabulum with the intensity of pain and disability of patients diagnosed with femoroacetabular impingement syndrome.  A retrospective analysis of the preoperative data of 182 patients (190 hips) was performed. Clinical variables such as age, gender, the practice of physical activity, and radiographic variables, such as the Wiberg and alpha angles, were evaluated.

Is There Any Difference Between a Spherical Marker and a Simple Coin for Hip Replacement Digital Planning?

 To evaluate the accuracy and differences between 2 types of metallic markers, sphere, and coin, for radiographic calibration in the preoperative planning of hip arthroplasty.  Four spherical metallic markers and four coins, both 25 mm in diameter, were placed on the greater trochanter, pubic symphysis, between the thighs, and on the table of the exam, for radiographic examination of the hip in 33 patients with hip prosthesis. The prosthesis head was used for calibration and two examiners measured the markers' image diameters, and the results were analyzed statistically.

Patient Education in Orthopedics: the Role of Information Design and User Experience.

Purpose Of Review: This narrative review will focus on concepts and methods of Information Design and User Experience for patient education in orthopedics, with osteoarthritis as an application example.

Recent Findings: Information design can make complex health information clear according to the needs of the patients. Digital health presents new opportunities to design scalable educational interventions and may be improved with User Experience Design.

Step down tests are the tasks that most differentiate the kinematics of women with patellofemoral pain compared to asymptomatic controls.

Background: Studies evaluating kinematics lead to different conclusions, not all changes appear in all assessed tasks and in all subgroups of patients with patellofemoral pain (PFP). The inconsistencies between studies could be reduced if we knew which task separates patients best from healthy controls.

Research Question: Identify which functional task, between gait, forward step down (FSD), lateral step down (LSD), stair ascent and descent and propulsion and landing phase of the single leg hop test (SLHT), differentiates the three-dimensional kinematics of women with patellofemoral pain from asymptomatic women.

Low-Level Laser Therapy (780 nm) on VEGF Modulation at Partially Injured Achilles Tendon.

Objective: The aim of this study was to analyze the modulatory effects of near infrared (780 nm) low-level laser therapy (LLLT) on the presence of the vascular endothelial growth factor (VEGF) in the partially injured Achilles tendons of rats.

Background: LLLT stimulates the healing process for Achilles tendon injuries, although the extent of the modulatory effect of LLLT on the VEGF levels found in the injured tendons remains unclear.

Methods: Sixty-five male Wistar rats were distributed in the following seven groups: LASER 1, 3, and 7 (10 partially injured Achilles tendons in each group, which were treated with LLLT for 1, 3, and 7 days, respectively); Sham 1, 3, and 7 (same injury, with simulated LLLT); Control group containing the five remaining animals and in which no procedures were performed.

Low-level laser therapy in IL-1β, COX-2, and PGE2 modulation in partially injured Achilles tendon.

This study evaluated IL-1β, COX-2, and PGE2 modulation in partially injured Achilles tendons treated with low-level laser therapy (LLLT). Sixty-five male Wistar rats were used. Sixty were submitted to a direct injury on Achilles tendon and then distributed into six groups: LASER 1 (a single LLLT application), LASER 3 (three LLLT applications), and LASER 7 (seven LLLT applications) and Sham 1, 3, and 7 (the same injury but LLLT applications were simulated).
