Robotic-assisted TKA leads to a better prosthesis alignment and a better joint line restoration as compared to conventional TKA: a prospective randomized controlled trial

Narendra V. Vaidya, Ajinkya N. Deshpande, Taufiq Panjwani, Rakesh Patil, Tanmay Jaysingani, Pratik Patil

Summary: The study found that the new semi-active robotic-assisted total knee arthroplasty is more accurate than conventional TKA in terms of mechanical axis deviation, joint line deviation, and coronal alignment of femoral and tibial prosthesis. However, the impact of joint line elevation difference on knee kinematics and flexion between conventional and robotic-assisted TKA requires further investigation.

Anterior Shoulder Instability Part I-Diagnosis, Nonoperative Management, and Bankart Repair-An International Consensus Statement

Eoghan T. Hurley, Bogdan A. Matache, Ivan Wong, Eiji Itoi, Eric J. Strauss, Ruth A. Delaney, Lionel Neyton, George S. Athwal, Leo Pauzenberger, Hannan Mullett, Laith M. Jazrawi

Summary: This study aimed to establish consensus statements on the diagnosis and treatment of anterior shoulder instability. Through a modified Delphi technique, experts from different countries reached unanimous agreement on various factors, including patient history evaluation, prognostic factors for nonoperative management, and Bankart repair. There was consensus on minimizing complications and anchor placement in Bankart repair, but no consensus on the optimal shoulder immobilization position.

Anterior Shoulder Instability Part II-Latarjet, Remplissage, and Glenoid Bone-Grafting-An International Consensus Statement

Eoghan T. Hurley, Bogdan A. Matache, Ivan Wong, Eiji Itoi, Eric J. Strauss, Ruth A. Delaney, Lionel Neyton, George S. Athwal, Leo Pauzenberger, Hannan Mullett, Laith M. Jazrawi

Summary: This study aimed to establish consensus statements on the Latarjet procedure, remplissage, and glenoid-bone grafting for anterior shoulder instability. A modified Delphi process was used with the participation of 65 shoulder surgeons from 14 countries. The results showed that a subscapularis split approach should be utilized for the Latarjet procedure and glenoid bone-graft, and the need for capsular repair with a glenoid bone graft was unclear. Remplissage procedure was indicated for off-track or engaging Hill-Sachs lesion without severe glenoid bone loss.

Blood Flow Restricted Exercise and Discomfort: A Review

Robert W. Spitz, Vickie Wong, Zachary W. Bell, Ricardo B. Viana, Raksha N. Chatakondi, Takashi Abe, Jeremy P. Loenneke

Summary: Blood flow restricted exercise can increase muscle size and strength, but it is often accompanied by discomfort. Factors such as applied pressure, cuff width, cuff material, sex, and training to failure may influence the discomfort experienced during exercise. Lower applied pressures and stopping short of task failure can attenuate discomfort.

Gender stereotypes: the impact upon perceived roles and practice of in-service teachers in physical education

Stacey Preece, Rachael Bullingham

Summary: This study found that in-service physical education teachers tend to hold gender stereotypes, including fixed views on gender roles, gendered sports and story character assumptions. Teachers usually do not attribute stereotype reproduction to themselves, and negative external pressures are often seen as the main reason for stereotypical practice, indicating that gender stereotypes are still prominent in physical education.

Evaluating the 35°C wet-bulb temperature adaptability threshold for young, healthy subjects (PSU HEAT Project)

Daniel J. Vecellio, S. Tony Wolf, Rachel M. Cottle, W. Larry Kenney

Summary: This study for the first time uses empirical physiological observations to examine the widely-publicized theoretical limit of 35 degrees C wet-bulb temperature for human adaptability to extreme environments. It found that uncompensable heat stress in humid environments occurs at wet-bulb temperatures significantly lower than 35 degrees C in young, healthy adults. Additionally, the study shows that uncompensable heat stress occurs at widely different wet-bulb temperatures depending on ambient vapor pressure.

Summary: The overall prevalence of injuries among CrossFit practitioners is 35.3%, with the most commonly injured areas being the shoulder, spine, and knee. Risk factors associated with injuries include older age, male sex, higher BMI, previous injuries, lack of coach supervision, and experience in CrossFit.

Summary: In reporting research in sport, it is important to define the level of expertise of the sample studied. This study aimed to assess the performance level of national and regional swimmers from different countries based on FINA points and propose a model for standardizing swimming research results. The study found significant disparities in FINA points between male and female swimmers from different countries in national and regional competitions.

Summary: Machine-learning methods accurately classified movement behaviours in free-living accelerometer data. Reallocating time from other behaviours to MVPA, and from sedentary behaviour to other behaviours, was associated with lower risk of incident CVD, and should be promoted by interventions and guidelines.

Summary: This study compared the effects of 8 weeks of isoinertial and cable-resistance training on motor skills performance and interlimb asymmetries in handball players. The results showed that the isoinertial training group had greater performance improvements and reductions in interlimb asymmetries, indicating that isoinertial resistance training is more effective than cable-resistance methodology.

Summary: This systematic review compares the accuracy of Bioelectrical Impedance Analysis (BIA) and Bioelectrical Impedance Vector Analysis (BIVA) with reference methods for assessing body composition in athletes. The review suggests that BIA and BIVA can be used for this purpose, provided that foot-to-hand technology, predictive equations, and athlete-specific reference values are used.

Summary: The study revealed that long-duration spaceflight leads to significant decreases in bone density and strength in astronauts, while pre-flight markers of bone turnover and exercise history can help identify individuals at risk for bone loss. Additionally, increasing training volume can help prevent loss of bone strength and density.

Summary: The study using systematic video analysis in professional male football revealed that sprinting and stretching are the main causes of acute hamstring injuries, with the biceps femoris being the most affected muscle. The research suggests that rapid movements with high eccentric demands of the posterior thigh are likely the main mechanism leading to hamstring injuries.
