The Effects of Heat Therapy During Immobilization and Rehabilitation on Muscle Atrophy and Strength Loss at Return to Sports in Healthy Humans.

Background: Animal research suggests that repeated heat exposures may stimulate skeletal muscle protein synthesis and downregulate protein degradation.

Hypothesis: Repeated heat exposures during ankle immobilization and rehabilitation would preserve human muscle strength and mass.

Study Design: Controlled laboratory study.

DYNEELAX Robotic Arthrometer Reliability and Feasibility on Healthy and Anterior Cruciate Ligament Injured/Reconstructed Persons.

Background: Anterior cruciate ligament (ACL) injuries are commonly assessed using clinical examination and magnetic resonance imaging, but these methods have limitations in reproducibility and quantification. Instrumented laxity measurements using devices, like the DYNEELAX®, offer an alternative approach. However, to date, there is no human data on the DYNEELAX® and the reliability of these devices remains a subject of debate, and there is no consensus on appropriate knee tightening levels for testing.

Patient-oriented educational Sports Medicine YouTube videos in Arabic have higher view counts in the Middle East and North Africa than their English versions.

Purpose: The present study aims to assess the impact of the local language on the view count of patient-oriented educational Sports Medicine videos in an Orthopaedic and Sports Medicine Hospital in the Middle East and North Africa.

Methods: An observational study on English and Arabic versions of Aspetar's YouTube channel patient-oriented educational video series was conducted in February 2023, comparing the view count and viewer characteristics. Included videos were posted either simultaneously or in English version first, in both languages, and shared on the same media platforms.

Short-term outcomes of anterior cruciate ligament reconstruction with or without lateral tenodesis or anterolateral ligament reconstruction: a retrospective cohort.

Purpose: This study aimed to compare the short-term outcomes of ACL reconstruction (ACLR) alone, ACLR with lateral tenodesis, and ACL and ALL reconstruction.

Methods: A retrospective cohort of prospectively collected data on all ACL procedures was performed at Aspetar Specialized Orthopaedic and Sports Medicine Hospital between January 2020 and January 2021. Patients were treated with ACLR alone, ACLR with lateral tenodesis, or ACLR with ALL reconstruction.

Radiological study of the knee joint line position measured from the fibular head and proximal tibial landmarks.

Restoring the joint line level is one of the surgical challenges during revision of total knee arthroplasty. The position of the tibial surface is commonly estimated by its distance to the apex of fibular head, but no study evaluating this distance accurately has been published yet. The purpose of this work was to study the distance between the knee joint line and the apex of the fibular head and the proximal tibia, particularly the tibial tuberosity.

Arthrodesis of the first metatarsophalangeal joint using convex and concave drills. A report on 50 cases.

The authors report their results after arthrodesis of the first metatarsophalangeal joint (MP) performed in 50 cases including 18 rheumatoid feet, 18 major hallux valgus deformities and 14 recurrent deformities. Preparation of the bone ends for arthrodesis was achieved using convex and concave drills and fixation was done with an axial screw. The patients were evaluated after an average of 12 months, using Kitaoka's score.

Comparative in vitro assessment of the primary stability of cementless press-fit acetabular cups.

Long-term stable osseointegration of porous-coated acetabular cups depends on bony ingrowth within their porous surface. For ingrowth to take place, one must ensure rigid initial fixation of the implant, by means of screws or by impaction or using a threaded ring. Primary stability is a prerequisite for long term stability through bony ingrowth.
