No influence of patient age on operative treatment outcome of osteochondral lesions of the talus: data from the German Cartilage Registry (GCR, KnorpelRegister DGOU).
The influence of patient age on the clinical outcome of surgically treated osteochondral lesions of the talus (OCT) is controversial. Aim of this study was to evaluate the 24 months follow-up data of the German Cartilage Registry (KnorpelRegister DGOU, GCR) regarding the influence of patient age on clinical outcomes after surgical OCT treatment. ⋯ Results of surgical therapy of OCTs are independent from patient age. There is no superiority of a specific surgical technique depending on patient age.

Reliability and utility of the new Belt et al. classification for revision of infected total knee arthroplasty.
The frequency of revisions in total knee arthroplasty (TKA) is rising. Various classifications of bone defects exist, each with its own limitations. Recently, Belt et al. have proposed a new classification for TKA revisions based on X-ray imaging. We evaluated the Belt et al. classification and verified if this new classification is reliable, and if it correlates with the implant used during revision surgery for periprosthetic joint infection. ⋯ The Belt at al. classification is reliable, but a classification which can predict the implant neded have to be developed.

Calculation of CT ideal screw path and safety angle before percutaneous sacroiliac screw placement.
Percutaneous sacroiliac screw placement is the main surgical approach to treat unstable posterior pelvic ring injuries. Intraoperative fluoroscopic imaging is an important part of safe sacroiliac screw placement. However, how to determine the right perspective view is challenging. We developed a trigonometric algorithm to verify how preoperative pelvic computed tomography (CT) can be used to predict ideal screw path and safety angle. ⋯ During preoperative planning, trigonometric calculations were used to determine the ideal screw placement angles and safety angle at the inlet and outlet of the screw path. Combined with intraoperative C-arm fluoroscopy, individualized screw insertion can help orthopedic surgeons quickly and accurately obtain intraoperative images and accurately determine the direction of screw insertion.
