Lateral Ulnar Collateral Ligament Reconstruction for Posterolateral Rotatory Instability After Failed Common Extensor Origin Release: Outcomes at Minimum 2-Year Follow-up.

Background: In patients with chronic lateral epicondylitis who have failed nonoperative treatment, open or percutaneous release of the common extensor origin (CEO) without subsequent reconstruction tends to result in good clinical outcomes. However, surgery can lead to iatrogenic injuries of the lateral collateral ligamentous complex, causing posterolateral rotatory instability (PLRI).

Purpose: To determine the clinical outcomes of lateral ulnar collateral ligament (LUCL) reconstruction using a triceps tendon graft after failed open CEO surgery.

Is Hip Arthroscopy an Adequate Therapy for the Borderline Dysplastic Hip? Correlation Between Radiologic Findings and Clinical Outcomes.

Background: Recent studies have shown that assessment of the lateral center-edge angle (LCEA) between 18° and 25° is not sufficient to adequately classify mildly dysplastic hips and that further radiological features should be considered. However, no correlation between different morphologic features and clinical outcomes has been investigated so far.

Purpose: To analyze the clinical outcomes of patients with different subtypes of borderline dysplastic hips who underwent arthroscopic surgery.

Translation of the Mayo Elbow Performance Score (MEPS) into German (MEPS-G).

Background: The Mayo Elbow Performance Score is a clinical assessment to rate the performance of the elbow from a medical and/or therapeutic perspective. It is simple and efficient to operate and therefore frequently used in research as well as in clinics. However, an adequate translation of the MEPS into the German language and a verification of the quality criteria for the use in the German health system are currently lacking.

Long-term outcome after all inside meniscal repair using the FasT-Fix system.

Purpose: Meniscal surgery is one of the most performed orthopaedic procedures. Because of its chondroprotective properties, meniscal repair should be attempted whenever possible. Several techniques are described in literature, e.
