Background: Symptomatic herniated discs are not compatible with physical activity due to severe pain and possible neurological deficits in the acute phase. Once this phase has subsided, it is important to plan an individualized load build-up. The influencing factors are structural damage, the type of sport previously practiced and training status, as well as pain and neurological deficits.

While lateral open wedge techniques are common for valgus deformities, the data about medial open wedge techniques for varus deformities is sparse. The aim of this study was to compare the biomechanical properties of medial and lateral open wedge osteotomies using a locking Tomofix® plate (DePuy Synthes, Oberdorf, Switzerland).

Background: One of complications of the reverse shoulder arthroplasty is acromion fractures, and its therapy is controversial. The aim of the study was to investigate the double-plate osteosynthesis for these fractures.
Methods: An acromion type III fracture according to classification of Levy was simulated in 16 human shoulder cadavers, and the specimens were randomly divided into two groups.
Purpose: The influence of the subscapularis tendon on reverse total shoulder arthroplasty (RTSA) has been discussed controversially. The aim of the study was to investigate the subscapularis-sparing approach for RTSA and the effect of the intact subscapularis tendon.
Methods: This retrospective comparative study included 93 patients.
Objective: Clinical outcome data for the novel minced cartilage procedure are sparse. While good results have been shown for the knee joint, this is the first report in the current literature regarding this increasingly important procedure in the glenohumeral joint.
Case Description: A 33-year-old handyman with a cartilage defect in the humeral head underwent an all arthroscopic one-stage cartilage repair with the AutoCart procedure (Arthrex GmbH, Munich, Germany).
Purpose: Torn anterior cruciate ligaments in children are rare injuries. The incidence of concomitant avulsion fracture in the skeletally immature patient is high. Reports of arthroscopic reconstruction in the literature are sparse.

In the literature stemless and canal sparing TSA showed good clinical and radiographic results, which were comparable to stemmed TSA.
Objective: The aim of this study was to determine the short-term clinical and radiological outcomes of a new stemless TSA design.

Purpose: Reconstruction of the medial patellofemoral ligament (MPFL) is an established procedure to restore patellar stability. Aim of this study is to evaluate the results of a dynamic MPFL reconstruction technique in a large university hospital setting.
Methods: Two hundred and thirteen consecutive patients with 221 knees were surgically treated for recurrent lateral patellar dislocation.
Background: This biomechanical cadaveric in vitro study aimed to evaluate and compare the dynamic elongation behavior and ultimate failure strength of tibial adjustable-length loop cortical button versus interference screw fixation in quadriceps tendon-based anterior cruciate ligament reconstruction.
Methods: Sixteen human quadriceps tendons were harvested and fixed into porcine tibiae using either biodegradable interference screw (n = 8) or adjustable loop device (n = 8) fixation. An acrylic block was utilized for femoral adjustable loop device fixation for both groups.
Introduction: Over the past decades many innovations were introduced in total knee arthroplasty (TKA) focusing on implant longevity and higher procedural precision; however, there are still a high number of dissatisfied patients. It was reported that better anatomical alignment may result in improved patient outcome; however, current technologies have limitations to achieve this. The aim of this video article is to describe the technique of individualized alignment in TKA with the use of image-based robotic assistance.
View Article and Find Full Text PDFToday, there is an almost endless variety of knee prosthesis models on the market from which the surgeon can choose. Although the designs appear closer and closer to one another, the industry makes a great effort to emphasise different features as beneficial and a stand-alone. It is increasingly difficult to keep an overview and to assess the clinical relevance of the diverse features.
View Article and Find Full Text PDFClinical scores and motion-capturing gait analysis are today's gold standard for outcome measurement after knee arthroplasty, although they are criticized for bias and their ability to reflect patients' actual quality of life has been questioned. In this context, mobile gait analysis systems have been introduced to overcome some of these limitations. This study used a previously developed mobile gait analysis system comprising three inertial sensor units to evaluate daily activities and sports.
