Is debridement beneficial for focal cartilage defects of the knee: data from the German Cartilage Registry (KnorpelRegister DGOU).
Focal cartilage defects of the knee are often treated with arthroscopic debridement. Existing literature discussing the benefit of debridement for small articular cartilage lesions is scarce, especially if the debridement was not part of a combined operative cartilage procedure including meniscal and ligament repair. The purpose of this study was to examine the patients´ benefit after arthroscopic debridement for the treatment of isolated focal chondral defects with or without partial meniscus resection. ⋯ An overall benefit of arthroscopic debridement for focal cartilage lesions of the knee could be conducted. Isolated cartilage defects seem to benefit from debridement irrespectively of size. In patients with large cartilage defects (> 2 cm2) and concurrent meniscal pathology expectation to improvement should be humbled. Effective reduction of pain by arthroscopic debridement remains unclear.

A two-portal technique using a flexible reamer system is a safe and effective method for transportal anterior cruciate ligament reconstruction.
A flexible reamer system (FRS) for transportal anterior cruciate ligament reconstruction (ACLR) has been developed to overcome the technical challenges of a rigid reamer system. The purpose of this study was to investigate the safety and effectiveness of the two-portal technique using an FRS by evaluating femoral tunnel geometry. ⋯ Retrospective case series; level of evidence, 4.

Optimal rotational positioning of tibial component in total knee arthroplasty: determined by linker surgical technique using a high definition CT.
The rotational alignment of femoral and tibial components is an important determinant of the success of Total Knee Arthroplasty (TKA). The optimal rotational position of the tibial component is still unclear. The purpose of this study was (1) to determine the pre-operative S-TEA (surgical-transepicondylar axis) derived tibialanteroposterior (AP) axis angle and postoperative tibial component axis angle using a "Bird's eye" high-definition CT image in TKA performed by Linker surgical technique; (2) to determine the femorotibial mismatch angle; and (3) to determine the optimal tibial component rotation in a well-aligned femoral and tibial components. ⋯ Level II.

Inducing life-like distal radius fractures in human cadaveric specimens: a tool for enhanced surgical training.
Surgical education consists often times of a discrepancy between necessary amount of provided operative teaching and amount of organizational and ward duties. Operative education is often cut to a minimum. As public awareness toward surgical competence raises, so must the educational system. Courses that provide pre-fractured cadaveric specimens can facilitate surgical teaching realistically, prior to operating on living patients. The aim of this study is to introduce a realistic distal radius fracture simulation setup. ⋯ A high energetic impulse induced by a custom-made drop-test bench can successfully simulate realistic distal radius fractures in cadaveric specimens with intact soft tissue. Furthermore, these pre-fractured specimens can be utilized in surgical education to provide a teaching experience as realistic as possible without harming living patients.
