[Isokinetic strength testing with different biomechanical demands on core strength: a comparison of military competitive athletes and soldiers with high occupational physical strain].

It is known that anthropometric data (weight, height, BMI, waist circumference and WHtR) and male gender are positively correlated with greater core strength, while age is negatively correlated. For competitive athletes with no significant differences in the anthropometric data stated above, there have hardly been any studies in which isometric core strength in a seated position is quantitatively compared among athletes in different sports. This study aimed to analyse different sports in well-trained athletes using military competitive sports as an example with regard to possible differences in core strength.

Early Rehabilitation with Exergame - Which Muscle Groups are Addressed by Bedside-Based Knee Exercises?

Background: Knee exercises are generally recommended following knee-related operations. Nevertheless, compliance in performing self-administered exercises is varying. The use of exergames may alter patient compliance.

App-based rehabilitation program after total knee arthroplasty: a randomized controlled trial.

Introduction: New app-based programs for postoperative rehabilitation have been developed, but no long-term study has been published to date. Thus, a prospective randomized control trial with 2-year follow-up was performed to evaluate the effectiveness of app-based rehabilitation (GenuSport) compared to a control group after total knee arthroplasty (TKA).

Methods: Between April and October 2016, 60 patients were enrolled in the study.

Coagulation monitoring and transfusion in major non-emergency orthopaedic surgery - An observational study.

Objective: Perioperative coagulation monitoring and transfusions were evaluated.

Methods: 70 cases were included. Time points: before (PRE), after surgery (POST), day 1, day 3, day 7.

Simplified Measurement of Maximum Strength After Knee Surgery: Application-Based Knee-Training Device Compared to Isokinetic Testing.

Context: Isokinetic testing is used as a standard tool in measuring strength in professional athletes. It is often used to evaluate improvement during rehabilitation. The disadvantages of isokinetic testing include its costs, the fact that it is not portable, and its risk of injury, which makes it not suitable for early postoperative rehabilitation.

Improving Maximal Strength in the Initial Postoperative Phase After Anterior Cruciate Ligament Reconstruction Surgery: Randomized Controlled Trial of an App-Based Serious Gaming Approach.

Background: Anterior cruciate ligament reconstruction surgery is one of the most common orthopedic procedures. One of the main factors that influence the outcome is regaining strength in the postoperative phase. Because anterior cruciate ligament reconstruction surgeries are often performed in young patients, we combined the concept of prehabilitation with an app-based serious gaming approach to improve maximal strength postoperatively.

Impact of aerobic exercise on muscle mass in patients with major depressive disorder: a randomized controlled trial.

Objective: Sarcopenia leads to physical function impairment and at least to increasing all-cause mortality. There are notes on reduced muscle mass in patients with major depressive disorder (MDD). Whether an exercise intervention counteracts low muscle mass in patients with MDD has not been studied so far.

[Injury prevention in amateur football with FIFA 11+ : What is implemented on the football pitch?].

Background: The warm-up and injury prevention program FIFA 11+ was developed to reduce injuries in recreational and amateur level football. Despite systematic education it is uncertain what amount of knowledge is passed down to the lower recreational level football players and what exercises are implemented in the daily routine. This study presents the summarized experiences of German coaches about the implementation of exercises on the football pitch.

Improved early outcome after TKA through an app-based active muscle training programme-a randomized-controlled trial.

Purpose: The purpose of this prospective randomized-controlled trial (RCT) was to evaluate if an app-based feedback-controlled active muscle training programme can be used to improve the outcome in the immediate postoperative period after total knee arthroplasty (TKA).

Methods: Sixty patients, with a median age of 65.9 years (range 45-84), awaiting primary TKA were randomized into a control and training group.

The determination of the validity of an application-based knee-training device.

The goals of knee rehabilitation are to improve range of motion and muscle status. The aim of the study was to investigate accuracy and reproducibility of a newly designed knee-training device (KT) under standardized laboratory conditions.Two application-based software programs, one to measure maximum force and the other intended to improve users' coordination were developed to be used on a tablet during exercises, wirelessly connected to KT placed under the popliteal fossa.

Fun During Knee Rehabilitation: Feasibility and Acceptability Testing of a New Android-Based Training Device.

Purpose: The initial goals of rehabilitation after knee injuries and operations are to achieve full knee extension and to activate quadriceps muscle. In addition to regular physiotherapy, an android-based knee training device is designed to help patients achieve these goals and improve compliance in the early rehabilitation period. This knee training device combines fun in a computer game with muscular training or rehabilitation.

Evaluation of the acceptability of a sphygmomanometer device in knee extension training following surgical procedures of the knee.

Background: The postoperative treatment after a standard surgical intervention such as knee arthroplasty, proximal tibial osteotomy or supracondylar osteotomy, can have an important impact on the overall treatment outcome. In most cases, outcomes are positively effected by patients receiving physiotherapy and occupational therapy. Basic movements and range of motion need to be learnt.

[Evidence-based therapy for tendinopathy of the knee joint : Which forms of therapy are scientifically proven?].

Tendinopathy in the region of the knee joint is a common pathological disorder. People active in sports, in particular, have a high probability of suffering from tendinopathy. Despite its high clinical relevance, the level of evidence of therapy options for tendinopathy in the knee region differs greatly.

The use of a modular system to convert an anatomical total shoulder arthroplasty to a reverse shoulder arthroplasty: Clinical and radiological results.

If a modular convertible total shoulder system is used as a primary implant for an anatomical total shoulder arthroplasty, failure of the prosthesis or the rotator cuff can be addressed by converting it to a reverse shoulder arthroplasty (RSA), with retention of the humeral stem and glenoid baseplate. This has the potential to reduce morbidity and improve the results. In a retrospective study of 14 patients (15 shoulders) with a mean age of 70 years (47 to 83) we reviewed the clinical and radiological outcome of converting an anatomical shoulder arthroplasty (ASA) to a RSA using a convertible prosthetic system (SMR system, Lima, San Daniele, Italy).

[Posttraumatic limitations in range of movement of the knee joint].

Limitations of range of movement of the knee joint are frequent sequelae of complex knee trauma. The subjective outcome is significantly compromised by loss of movement of the knee joint. This article discusses the osseous and soft tissue factors contributing to loss of movement of the knee joint after trauma.

Development of a fixation device for robot assisted fracture reduction of femoral shaft fractures: a biomechanical study.

Robot assisted fracture reduction of femoral shaft fractures provides precise alignment while reducing the amount of intraoperative imaging. The connection between the robot and the fracture fragment should allow conventional intramedullary nailing, be minimally invasive and provide interim fracture stability. In our study we tested three different reduction tools: a conventional External Fixator, a Reposition-Plate and a Three-Point-Device with two variations (a 40 degrees and a 90 degrees version).

The relationship between trochlear dysplasia and medial patellofemoral ligament rupture location after patellar dislocation: an MRI evaluation.

The medial patellofemoral ligament (MPFL) and the native trochlear geometry represent two of the most critical components of patellofemoral stability. We sought to define the relationship between trochlear dysplasia and MPFL rupture location in patients with documented patellar dislocations. We hypothesized that patients with lower grades of trochlear dysplasia would have patellar based MPFL ruptures, while patients with higher grade dysplasia would have femoral-sided ruptures.
