Effects of a Specific Trunk and Shoulder Strength Training Program on Throwing Velocity and Accuracy: A Study Among Hungarian First-League Female Handball Players.

The aim of the study was to record shoulder and trunk stability of elite female handball players and to investigate their effect on throwing velocity and accuracy. 151 female handball players (9 teams in total) from the Hungarian first league participated in a mid-season conditional survey. The study included tests of trunk and shoulder stability, and measurements of factors affecting shoulder stability, as well as throwing speed and throwing accuracy.

Low Femoral Tunnel Widening Incidence Rate After ACL Reconstruction Using Patellar Tendon Graft with Press-Fit Fixation.

Background: Femoral tunnel widening after ACL reconstruction is a common phenomenon. We hypothesized that using a patellar tendon graft with a press-fit fixation technique without any fixation device reduces the incidence of femoral tunnel widening.

Methods: This study was conducted on 467 patients with ACL surgery between 2003 and 2015.

A Case Series of SARS-CoV-2 Reinfection in Elite Athletes.

Objectives: The actual frequency and the risk factors of SARS-CoV-2 reinfection is still a matter of intense scientific discussion. In this case series, we report three elite athletes who underwent COVID-19 reinfection with a short time frame.

Case Presentations: As a part of contact tracing, three speed skaters (22-, 24-, and 29-year-old males) were found to be SARS-CoV-2 positive by polymerase chain reaction (PCR) tests.

Short and mid-term characteristics of COVID-19 disease course in athletes: A high-volume, single-center study.

Introduction: At the pandemic's beginning, significant concern has risen about the prevalence of myocardial involvement after SARS-CoV-2 infection. We assessed the cardiovascular burden of SARS-CoV-2 in a large cohort of athletes and identified factors that might affect the disease course. We included 633 athletes in our study on whom we performed extensive cardiology examinations after recovering from SARS-CoV-2 infection.

Outcomes After Arthroscopic Anterior Shoulder Stabilization in Professional Handball Players.

Background: Although numerous studies have reported on the redislocation rate and functional results of arthroscopic treatment for anterior shoulder instability in athletes, they have not disclosed outcomes in the high-risk group of elite handball players.

Purpose: To investigate the postoperative outcomes of arthroscopic treatment for anterior shoulder instability as well as the return-to-sport (RTS) rate in professional handball players.

Study Design: Case series; Level of evidence, 4.

Introducing the National Institute for Sports Medicine in Hungary: a complex sports medical healthcare and screening system.

The Hungarian National Institute for Sports Medicine (NISM) was founded in 1952 to provide medical coverage for national teams, screening and periodic health evaluation (PHE) for all Hungarian athletes. The system of 'all in one and ASAP' evolved by now to a specific state-funded healthcare provider with complex sports medical and sport-related services available for athletes. The NISM created a countrywide network to make health clearance available for all athletes close to their place of residency.

Comparative study of the use of computer assisted navigation system for axial correction in medial unicompartmental knee arthroplasty.

The aim of our study was to compare the use of the Orthopilot Navigation system with conventional non-navigation technique for medial UKA with respect to the intraoperative mechanical limb alignment measurements and correlation with the postoperative radiological measurements. The postoperative mechanical limb alignment axes of 51 consecutive medial unicompartmental knee arthroplasty performed by a single surgeon over a 12-month period were measured. The cases were randomly assigned to two groups of which 21 cases were performed using conventional non-navigation based technique and 30 cases were performed using the Orthopilot Navigation System.

Living related donor allograft for revision anterior cruciate ligament reconstruction in a child: a case report.

Revision ACL reconstruction poses several challenges for the surgeon in terms of the timing of surgery and the limited graft choices. To our knowledge, there is currently no published data with regards to revision ACL reconstruction in a child. We describe the case of a 12-year-old girl who had a re-injury 4.

Anatomical study of the human anterior cruciate ligament stump's tibial insertion footprint.

The aim of this study is to define the topographical relationship of the anatomical bundles of the human anterior cruciate ligament's (ACL) stump over the tibial insertion site. Between January and April 2007, a total of 36 resected tibial plateaus were retrieved from patients who underwent total knee replacements. These samples had intact cruciate ligaments with no major osteophyte around the ACL tibial insertion footprint.

Femoral press-fit fixation technique in anterior cruciate ligament reconstruction using bone-patellar tendon-bone graft: a prospective clinical evaluation of 285 patients.

Background: The security of the graft fixation is an important factor of anterior cruciate ligament reconstruction, especially in the early postoperative period.

Hypothesis: The femoral press-fit fixation technique is a safe, alternative technique for the fixation of the bone-patellar tendon-bone graft.

Study Design: Case series; Level of evidence, 4.

[Femoral press-fit fixation in anterior cruciate ligament reconstruction: postoperative histological examination of bone block incorporation in pigs].

Introduction: The histological properties of the femoral press-fit fixation in anterior cruciate ligament reconstruction have not been extensively examined. The purpose of the study was to analyse the histological properties of the bone-patellar tendon graft in the bone tunnel area during the early stages of healing in an animal model. Furthermore the authors wanted to draw conclusions for the postoperative rehabilitation program on the basis of their data.

[Prevalence of patellofemoral pain syndrome. Evaluation of the role of biomechanical malalignments and the role of sport activity].

Introduction: Disorders around the patella are the most frequent knee complaints seen in adolescents. In the literature many intrinsic and extrinsic risk factors have been linked to Patellofemoral Pain Syndrome (PFPS), but the role of these risk factors is controversial.

Aim: The goal of this study was to evaluate the prevalence of PFPS in a group of adolescents aged 12-20 years in Hungary, and to gain more information on the relationship between the biomechanical anomalies of the lower extremity and the PFPS.

Development of a new activity score for the evaluation of ankle instability.

Background: Tegner and Lysholm described their generally acknowledged activity score in 1985. It was originally tested for knee ligament injuries, but for the past 17 years it has been used for other joint evaluations as well. The development of already existing and new kinds of sports, differences between knee and ankle loading, and different injury rates provided reasons for developing an ankle-specific activity score.

Percutaneous Achilles tendon repair with and without endoscopic control.

One hundred and fifty six patients were treated using the modified double suture technique for percutaneous Achilles tendon repair between 1994 and 1998. Endoscopy was used in 67 cases. The first ten cases were dropped (learning curve), 57 were followed (E-group).

[Femoral press-fit fixation technique in anterior cruciate ligament reconstruction. Preliminary report].

Unlabelled: The authors have reported the experiences at femoral press-fit fixation technique used in anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft. Their surgical technique have been described and early results have been compared with those from anterior cruciate ligament plasties with the interference screw fixation technique during a prospective study.

Patients And Methods: 665 anterior cruciate ligament reconstructions were performed between September 1997 and August 1999 at the Department of Sports Surgery of the National Institute for Sports Medicine.
