Arterial complications following total knee arthroplasty are rare but carry a high risk of significant morbidity and mortality. Herein, the authors report a case of pseudoaneurysm in a branch of a high-division anterior tibial artery caused by laceration by the retractor following primary total knee arthroplasty in a 72-year-old woman. ⋯ The diagnosis was confirmed by arteriography and the patient was successfully treated using endovascular embolization without long-term complications. Because of the high risk of progression to a potentially limb- or life-threatening condition, it is important to discuss the risk factors for this complication, as well as its early diagnosis and treatment methods.

Clinical Trial
[Tibial defects and infected non-unions : Treatment results after Masquelet technique].
The treatment of non-unions with large bone defects or osteitis is a major challenge in orthopedic and trauma surgery. A new concept of therapy is a two-step procedure: Masquelet technique according to the diamond concept. ⋯ The two-step bone grafting method in the Masquelet technique used for tibia non-unions according to the diamond concept is a promising treatment option. Its application for tibia shaft non-unions with large bone defects or infections means a high degree of safety for the patient.

Controlled Clinical Trial
[Arthroscopic tenodesis or tenotomy of the long head of the biceps tendon in preselected patients : Does it make a difference?]
Are there clinical, cosmetic and/or structural differences between tenotomy and tenodesis of the long head of the biceps tendon (LHB) in patients selected according to commonly used indication criteria? ⋯ In patients preselected according to routinely used indication parameters (e.g. age, BMI and functional requirements of the shoulder) both LHB-TD and LHB-TT can achieve good to very good functional and cosmetic results with high patient satisfaction.

The results after acetabular component revision are very heterogeneous, irrespective of the use of established or new components. This could be due to a lack of treatment standards for new revision components. The Trabecular Metal™ (TM) revision system, through its modularity, allows for an individual intraoperative reconstruction of the acetabular defect with a single implant system. It was the aim of this study to investigate the results of acetabular revision with the TMT system taking into consideration the utilized components and the acetabular defect. ⋯ The modular TMT system shows low revision rates. The modularity of the system allows for a safe and intraoperative adaptation to the individual acetabular defect without the need for extensive preoperative imaging or custom-made implants.

Review Meta Analysis
[Characteristics of elective hip replacement in the elderly].
Due to demographic changes the number of elderly patients undergoing hip replacement surgery is increasing. In order to ensure safe treatment of elderly patients, age-specific medical factors must be taken into consideration. ⋯ Out of 3166 patients a total of 439 were over 80 years old (average age 84 years). It can be concluded from the scientific literature and from own data that elective hip replacement surgery in elderly patients is a technically safe procedure; however, the risk profile of each patient must be thoroughly analyzed so that in the event of even minor signs of potential complications countermeasures can be taken in good time.
