Bipolar Lesions of the Knee Are Associated With Inferior Clinical Outcome Following Articular Cartilage Regeneration. A Propensity Score-Matched Analysis Including 238 Patients of the German Cartilage Registry (KnorpelRegister DGOU).

Purpose: To determine whether bipolar lesions (BL) are associated with inferior clinical outcome following articular cartilage regeneration (CR) compared to unipolar lesions (UL).

Methods: A registry-based study, including patients undergoing isolated CR for focal knee cartilage lesions was performed. Lesions were considered UL or BL depending on the opposing cartilage.

Integrated clinical case discussions - a fully student-organized peer-teaching program on internal medicine.

Background: In response to students´ poor ratings of emergency remote lectures in internal medicine, a team of undergraduate medical students initiated a series of voluntary peer-moderated clinical case discussions. This study aims to describe the student-led effort to develop peer-moderated clinical case discussions focused on training cognitive clinical skill for first and second-year clinical students.

Methods: Following the Kern Cycle a didactic concept is conceived by matching cognitive learning theory to the competence levels of the German Medical Training Framework.

Effect of Previous Knee Surgery on Clinical Outcome After ACI for Knee Cartilage Defects: A Propensity Score-Matched Study Based on the German Cartilage Registry (KnorpelRegister DGOU).

Background: Autologous chondrocyte implantation (ACI) is an established procedure for the treatment of cartilage damage in the knee joint. At present, it is still unclear how previous surgery influences outcome after ACI.

Purpose: To evaluate the effect of previous knee surgery related or nonrelated to the treated cartilage defect on clinical outcome after ACI for knee cartilage defects.

Factors correlating with patients' satisfaction after undergoing cartilage repair surgery-data from the German Cartilage Registry (KnorpelRegister DGOU).

Subjective patient satisfaction is the most relevant parameter for assessing the success of treatment after orthopaedic surgery. The aim of the present study was to correlate patient-reported outcome parameters (i.e.
