Refixation of anterior cruciate ligament (ACL) tears and augmentation using an Internal Brace® (Arthrex Inc., Naples, FL, USA) has become increasingly popular in recent years. The aim is to preserve the native ligament structure and, thus, improve clinical outcomes.

Minimally invasive stabilization of osteoporotic fractures of the posterior pelvic ring to ensure rapid and low-pain mobilization and timely fracture healing while avoiding progressive fracture instability.

Stabilization of the distal fibula and tibia to enable elongation-free healing of the ruptured syndesmotic ligaments.

Addressing all injured structures and medial stabilization against both valgus stress and rotation.

Anatomical reconstruction of the posterior cruciate ligament (PCL) with suture tape augmentation to enhance primary stability.

Restoration of passive medial stability of the patella by reconstruction/augmentation of the medial patellofemoral ligament complex.

Treatment of symptomatic Achilles tendinopathy.

Arthroscopy of the ankle joint is one of the standard procedures for treating many pathologies of the ankle joint. Ventral and posterior arthroscopy can be performed. The aim is to gain an overview of the joint using minimal incisions. There are many indications to perform ankle arthroscopy.

Arthroscopic matrix-associated bone marrow stimulation enables treatment of symptomatic osteochondral lesions of the ankle joint to alleviate pain and improve function.

Rheumatoid arthritis (RA) is a chronic inflammatory, immune-mediated disease of the musculoskeletal system that predominantly affects the hands and feet. The introduction of highly potent biologic disease-modifying drugs (bDMARDs) has led to a reduction in severe joint destruction and surgical interventions over the last two decades. Nevertheless, hand surgery remains an essential component of interdisciplinary therapy. Joint-preserving measures such as selective arthroplasty and partial arthrodesis are increasingly being performed today instead of arthrodesis, which was more common in the past. At the same time, the perioperative management of biologics is individually adapted to minimize the risk of infection. The following article draws on more than 30 years of personal experience in the treatment of patients with underlying rheumatic diseases and discusses current treatment recommendations for the hand and wrist.

Identification and treatment of concomitant intra-articular pathologies, verification of syndesmotic instability, debridement of syndesmotic structures in chronic injuries, reduction, and retention of the fibula in the distal tibiofibular joint.

Long-term stable fixation of the leg to the remaining ilium or sacrum following internal hemipelvectomy including resection of the acetabulum.

The goal of the fluoroscopically controlled tunnel positioning in anterior cruciate ligament (ACL) revision surgery is the prevention of malpositioning of femoral and tibial tunnel resulting in a reduced risk of rerupture of the ACL graft.

Correction of a double varus deformity and an increased tibial slope.

Improvement of flexion and thereby restoration of function of the knee joint as well as pain reduction by proximalization of the tibial tuberosity in combination with arthrolysis and release of the patellar retinaculum.

Treatment of pain and hypaesthesia caused by radial tunnel syndrome and functional deficits caused by supinator lodge syndrome. The objective for chronic nerve compression is containment to prevent further damage.

Conservative treatment using a backpack bandage (RSV) for clavicle fractures in children and adolescents serves to restore anatomy and function. The technique used in adult patients with elastic stable intramedullary nailing (ESIN) from the medial end of the clavicle involves the risk of growth disturbance of the growth plate, which has been open for a very long time; in addition, a cosmetically disturbing scar usually forms there. Treatment with an intrafocal intramedullary nailless osteosynthesis allows length and axis to be restored within the age-specific correction limits using a soft tissue-sparing surgical method in adolescents with, among other things, severe shortening of the fracture. Sufficient stability ensures early functional follow-up treatment without weight-bearing.

The aim of this surgical technique is fracture healing with anatomical alignment and less implant irritation due to smaller, low-profile plates. Equal to superior stability is provided compared to single superior- or anterior-based plates.

To achieve stable fixation to allow early mobilization by using a low profile contoured biplanar implant to avoid soft tissue problems and to minimize need for implant removal.
