Mobile App-Based Monitoring of Recovery After Knee Osteotomy: Patients Take Approximately Five Months to Return to Preoperative Step Counts Despite Limited App Uptake.

Introduction: This study aimed to assess the feasibility of using mobile application (app) technology for monitoring recovery after knee osteotomy and to determine the time required for patients to return to their preoperative step counts.

Methods: This retrospective study included 329 patients who underwent coronal realignment surgery, including high tibial osteotomy (HTO) or distal femoral osteotomy (DFO) with a minimum follow-up of 1 year. The patients were grouped based on the type of osteotomy performed, i.

Blood flow restriction-enhanced platelet-rich plasma: A pilot randomised controlled trial protocol.

Purpose: To assess platelet-rich plasma (PRP) changes in platelet and leucocyte count, insulin-like growth factor 1 (IGF-1), and interleukin 6 (IL-6) concentration after bilateral low-load knee extensions under blood flow restriction (BFR).

Methods: The present randomised controlled trial protocol will include two groups: the intervention group, which will undergo bilateral knee extensions under BFR, and the control group, which will perform bilateral knee extensions without BFR. Participants will be randomly allocated in a 1:1 ratio.

One-stage revision anterior cruciate ligament reconstruction: Preoperative evaluation, planning and surgical techniques. A review of current concepts.

Unlabelled: The increased rate of anterior cruciate ligament (ACL) tears has led to a greater number of revisions. Revision surgery can be performed in one or two stages. Single-stage revision ACL reconstruction (ssRACLR) may be performed when prior tunnels can be re-used or bypassed whereas a two-stage procedure is indicated when bone grafting of dilated tunnels prior to revision is necessary.

Nerve transfer of the median flexor pollicis brevis branch to the deep branch of the ulnar nerve for ulnar nerve palsy: a cadaveric feasibility study.

An ulnar nerve (UN) palsy is devastating for hand function, resulting in an intrinsic minus position or claw hand with a loss of pinch grip. Distal nerve transfers facilitate faster reinnervation of hand intrinsic muscles in cases of proximal ulnar nerve lesions. The traditional anterior interosseous nerve (AIN) to UN motor transfer is commonly used, however, this still leads to long reinnervation times for the distal intrinsic muscles, important for the thumb to index pinch grip.

Evolution of injury burden in Qatari professional football - 8 season data from the Aspetar Injury and Illness Surveillance Programme.

Prospectively collected injury surveillance data are essential for designing and implementing injury prevention programmes. We investigated the incidence, characteristics and patterns of professional football injuries in Qatar, providing details on the most observed injuries' burden. We prospectively recorded individual time-loss injuries and training/match exposure from 17 professional football teams in Qatar during 8 seasons (2014/15 to 2021/22).

Effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders: A comprehensive systematic review with meta-analysis.

Background: Usually, patients with hand, wrist/forearm disorders report musculoskeletal complaints in the shoulder. Although, role of scapula is fundamental for movement and functional stability across the upper limb kinetic chain; however, there are no systematic reviews and meta-analyses that have analyzed the effect of scapular exercises in these patients.

Purpose: This study aimed to determine the effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders.

This study aims to evaluate the impact of hypothyroidism on 90-day medical complications as well as 2-year implant related complications and revision rates following TSA.

Methods: This retrospective database analysis evaluated patients who underwent TSA between October 1, 2015, and March 9, 2022.

Peak Oxygen Consumption Scaled to Body Composition Is Associated With Mortality and Morbidity in People With a Fontan Circulation.

Background: Peak oxygen consumption (peak O) is traditionally scaled by body mass, but it is most appropriately scaled by fat-free mass. However, it is unknown whether peak O scaled by fat-free mass is associated with mortality and morbidity in people with a Fontan circulation. The aim of this study was to assess the associations between different expressions of peak O with mortality and morbidity in people with a Fontan circulation.

Limited evidence for the usage of renin-angiotensin-aldosterone pathway blockers to prevent arthrofibrosis after total knee arthroplasty. A systematic review of clinical evidence.

Purpose: Despite advances in surgical techniques and rehabilitation protocols, arthrofibrosis following total knee arthroplasty (TKA) still has poor outcomes. In the last decade, attention has been focused on the pathogenesis and cascade of events leading to the development of fibrosis. Currently, one of the most promising approaches consists in the indirect antagonisation of transforming growth factor beta 1 () through the downregulation of the renin-angiotensin-aldosterone system (RAAS).

Methods: The translations adhered to the established international criteria and underwent subsequent validation among 130 Arabic-speaking athletes from Jordan and Qatar. The validation process involved comparison against existing Arabic sleep questionnaires to ensure linguistic and cultural appropriateness.

Effects of thermal interventions on skeletal muscle adaptations and regeneration: perspectives on epigenetics: a narrative review.

Recovery methods, such as thermal interventions, have been developed to promote optimal recovery and maximize long-term training adaptations. However, the beneficial effects of these recovery strategies remain a source of controversy. This narrative review aims to provide a detailed understanding of how cold and heat interventions impact long-term training adaptations.

Low-dose carbon monoxide inhalation to increase total hemoglobin mass and endurance performance: scientific evidence and implications.

Recently, chronic intermittent inhalation of low-dose carbon monoxide (CO) has been postulated as a practice to increase total hemoglobin mass with potential beneficial effects on endurance performance. In this perspective article, we discuss the potential performance enhancing capabilities as well as the safety concerns, which include individual variability in CO response, and acute and chronic health effects. It is also important to note that according to the World-Anti-Doping-Agency (WADA), CO inhalation could fall under "" and therefore could be considered a prohibited method if used as a non-diagnostic tool.
