Introduction
I started focusing on shoulder surgery during my studies. Philipp Heuberer MD, who was my mentor in Vienna, taught me how to do proper research and guided me performing my diploma thesis, which has been published recently in the American Journal of Sports Medicine.
I started my training as an orthopedic trauma surgeon in September 2019 in the Trauma Hospital in Linz, and changed to Barmherzige Schwestern Hospital in 2021, where I help with ongoing research.

Glenoid implant position and fixation are challenging in severe glenoid defects in reverse total shoulder arthroplasty (rTSA). Custom-made glenoid implants are metal augmented implants that are specially produced for a certain defect. They provide the restoration of the joint line and proper fixation. This retrospective data analysis investigated t...
Background: Data on the effects of weight training on joint morphology are mostly restricted to muscle gain. However, in many circumstances, it is not stated if there are negative consequences for the joints and their surrounding components. This study was conducted to explore whether long-term excessive resistance training (RT) causes hidden patho...
Background
The rotator cuff is known to consist of 2 macroscopically visible layers that have different biomechanical properties. Sometimes the inferior layer may be neglected during rotator cuff repair. However, it is controversial whether double-layer (DL) repair is superior to single-layer (SL) repair in terms of retear rate and outcome.
Purpos...
Background
Accurate positioning of the glenoid component in reverse total shoulder arthroplasty is important since it reduces prosthesis-related complications. Conventional instrumentation is still the gold standard. However, patient-specific instrumentation using 3-D printed guides, as well as computer-assisted navigation, is gaining more and more...
Background: Short-stem total hip arthroplasty (THA) has gained popularity due to its bone-sparing technique, but its outcomes in patients with obesity remain uncertain. The aim of this study was to investigate the impact of obesity on postoperative subsidence and clinical outcomes after short-stem THA. Methods: A retrospective cohort study with a m...
Joint cartilage damage is a common condition, and various approaches exist to address these defects. Whenever conservative treatments have been exhausted or are inadequate, surgery should be taken into consideration. However, it is essential to consider the size of the damage as well as the subchondral bone involvement. As joint replacement is not...
Background: Distal triceps brachii tendon rupture (DTTR) is a relatively rare injury that is common in bodybuilding and high-intensity contact sports and can lead to significant functional impairment of the elbow joint. This study was conducted to evaluate clinical outcomes and the rate of return to sports among competitive bodybuilders and high-de...
Background
The long head of the biceps tendon (LHBT) is a well-known source of pain in the shoulder, especially in active patients.
Purpose
To evaluate the outcomes and return-to-sports rate after all-arthroscopic suprapectoral tenodesis of the LHBT using a small knotless anchor.
Study Design
Case series; Level of evidence, 4.
Methods
In this re...
Background: Reversed total shoulder arthroplasty (RTSA) is an established surgery for many pathologies of the shoulder and the demand continues to rise with an aging population. Preoperative planning is mandatory to support the surgeon’s understanding of the patient’s individual anatomy and, therefore, is crucial for the patient’s outcome. Methods:...
Downhill-mountain biking (DMB) is a high-risk sport and often leads to several injuries, especially in non-professional athletes. We retrospectively analyzed the most common injuries and profiled the injury mechanism. Until now, there is no such analysis of injuries by non-professional mountain bike athletes. We collected patient data from patients...
Background:
Total hip arthroplasty (THA) affects the biomechanics of the hip and the patient gait. The stem design influences femoral lever ratios and tissue trauma. Biomechanical changes such as these have the potential to induce knee arthritis. A varus or valgus configuration of knee arthritis is formed by asymmetric loadings. The aim of this st...
Background and Objectives: Short-stem total hip arthroplasty has become increasingly popular in recent years. While many studies have shown excellent clinical and radiological results, very little is known about the learning curve for short-stem total hip arthroplasty through an anterolateral approach. Therefore, the aim of this study was to determ...
Rotator cuff tear arthropathy (CTA) is the most common reason for reverse total shoulder arthroplasty (RSA). There is minimal understanding of the natural progression of osteoarthritis of the shoulder and of the morphologic differences between men and women and between younger and older patients. This trial comprised 309 patients (342 shoulders) wh...
Reverse total shoulder arthroplasty presents itself sometimes as challenging when it comes to addressing massive bone loss, either in primary or revision settings. Custom components recently have made their way into shoulder prosthetics and are meant to help in the case of extensive glenoid bone destruction. Because of strict indication and the fai...
Background
Severe acetabular defects require special treatment with either impaction bone grafting, metal augmented cups or cup-cage constructs. Even these options are often not adequate, especially in hips with Paprosky type 3 defects with loss of anterior and posterior columns. This study investigates the clinical and radiological outcomes of cus...
Purpose
To compare functional outcomes and magnetic resonance image (MRI) tendon integrity following either the suture bridge or the knotless cinch-bridge technique used for arthroscopic double-layer rotator cuff repair.
Methods
37 prospectively enrolled patients (46–76 years), who were treated with arthroscopic double-layer rotator cuff repair (g...
The voluntary contraction of the abductor pollicis brevis (APB) muscle can be suppressed cortically with a suprathreshold TMS pulse (cortical silent period CSP) and by cutaneous noxious stimulus (cutaneous silent period CuSP).
CSP measures the intracortical inhibition produced by the activation of the GABAB interneurons that synapse on pyramidal n...
