Comparative StudyVarus and valgus stress tests after total knee arthroplasty with and without anesthesia.
Retrospective studies demonstrated inadequate soft tissue balance is associated with the long-term outcome of total knee arthroplasty (TKA). However, most of these studies have evaluated the joint laxity only postoperatively without anesthesia. Therefore information about the effect of anesthesia on knee laxity is important for soft tissue balancing at the time of surgery. This study was conducted to determine how anesthesia affects the varus and valgus stress tests after TKA. ⋯ Anesthesia significantly influenced knee joint laxity after TKA. The findings of this study suggest that muscular forces impart a stabilizing force across the joint.

Case ReportsPathological fracture of the patella due to an atypical located aneurysmal bone cyst: verification by means of ultrasound-guided biopsy.
We report on a rare case of an atypical located aneurysmal bone cyst (ABC) in the patella presenting with pathological fracture after trauma. ⋯ As shown in this rare case of an atypical aneurysmal bone cyst of the patella, the quite seldom but sometimes possible ultrasound-guided biopsy of intraosseous lesions can help to achieve the diagnostic clarification and should also be taken into account as a non-standard procedure.

Increased risk for extended acetabular reconstruction in failed hip resurfacing as compared to failed total hip arthroplasty.
Hip resurfacing (HR) is intended to preserve the femoral bone stock during primary arthroplasty. On the other hand, little has been reported regarding the intraoperative need of bone reconstruction for extended acetabular defects during hip resurfacing revision. Thus, the aim of the presented study was to identify whether there is an increased need for acetabular bone reconstruction in HR revision surgery. ⋯ This study provides evidence that revision of failed HR devices is associated with an increased risk for extensive acetabular defects. Furthermore, the preoperative radiographic assessment of HR devices often underestimates the intraoperative acetabular defect. Surgeons should be aware of this fact not to technically underestimate HR revision procedures.

Influence of preparation and football skill level on injury incidence during an amateur football tournament.
Scientific studies on injury characteristics are rather common in professional football but not in amateur football despite the thousands of amateur football tournaments taking place worldwide each year. The purpose of this study was to evaluate the preparation and injury patterns of players of two different football skill levels who participated in an international amateur football tournament. ⋯ For the first time, this study presents detailed information on the injury incidence and injury patterns of an amateur football tournament. Less-trained recreational players sustained significantly more injuries than better-trained amateur players, probably due to the lack of sufficient preparation before the tournament. Preventive strategies against overuse and traumatic injuries of recreational football players should start with regular training and warm-up programmes in preparation for a tournament.

Meta Analysis Comparative StudyA meta-analysis comparing total disc arthroplasty with anterior cervical discectomy and fusion for the treatment of cervical degenerative diseases.
To evaluate the efficacy and safety of total disc arthroplasty (TDA) and anterior cervical discectomy and fusion (ACDF) for treating cervical degenerative diseases. ⋯ This meta-analysis revealed that the clinical outcomes of TDA are equivalent or superior to ACDF.
