Injectable autologous chondrocyte implantation in acetabular cartilage defects: 2-year minimum clinical and MRI results.
Early results using injectable autologous chondrocyte implantation (ACI) for the treatment of full thickness acetabular cartilage defects have been promising. However, so far there is no information on radiological results after injectable ACI using spheroids. The purpose of this sturdy was to (1) investigate the quality of tissue repair on MRI and (2) investigate the correlation between the MRI results and clinical results at a minimum follow-up of 24 months after third generation ACI in full thickness acetabular cartilage defects. It was hypothesized that ACI shows good MRI results in patients with large full thickness acetabular cartilage defects 24 months after surgery. It was also hypothesized that there is a correlation between postoperative clinical and MRI morphological results at a minimum follow-up of 24 months. ⋯ Despite the large acetabular cartilage defects included in this study, ACI showed good MRI results with complete defect fill in 87.5% after a minimum 24-month follow-up. Statistically significant correlation of MRI and clinical results could only be seen with the item defect fill. Further research with longer follow-up is needed to evaluate the long-term results of ACI in acetabular cartilage defects.

Descriptive analysis and short-term follow-up clinical results of osteochondral lesions of the distal tibia based on data of the German Cartilage Register (Knorpelregister® DGOU).
An increasing number of ankle injuries with osteochondral lesions (OCL) also include lesions of the distal tibia. Therefore, the German Cartilage Society database is used to describe and examine the characteristics of these lesions and, early on, the results of different surgical therapies on the clinical outcome. ⋯ This study presents baseline data of OLDT based on data from a large database. BMS and scaffolds were the treatment of choice but did not present significant improvement after a 1-year follow-up.

Clinical TrialMechanical failure of total hip arthroplasties and associated risk factors.
Mechanical failure of total hip arthroplasties is a rare but devastating complication. With increasing numbers in primary arthroplasty implantation, revision surgeries are indicated more often. Therefore, understanding the mechanism and the location of failure is essential in determining proper treatment. Aim of this study was to identify mechanical failures of all total hip arthroplasties performed in a major academic center as well as the associated risk factors such as BMI and sports. ⋯ III, Retrospective Trial.

Diagnostic value of the lateral femoral notch sign and kissing contusion in patients with anterior cruciate ligament injuries: a case-control study.
The lateral femoral notch sign (LFNS) and the kissing contusion (KC) are two indirect signs of anterior cruciate ligament (ACL) injuries. They can be used to diagnose ACL injuries. ⋯ The LFNS and KC have strong clinical significance in the diagnosis of ACL injuries. A deeper notch often indicates a more complex knee injury. Notch depth equal to 0.72 mm can be basically considered as the optimal cut-off point for LFNS in statistics.

Distal radius fracture with concomitant ulnar styloid fracture: does distal radioulnar joint stability depend on the location of the ulnar styloid fracture?
Studies are conflicting regarding the relationship between ulnar styloid fracture (USF) location and distal radioulnar joint (DRUJ) instability in patients with distal radius fracture (DRF) and concomitant USF. The objective of this study was to determine the association of USF location with TFCC foveal tear and factors associated with DRUJ instability in patients with both DRF and USF. ⋯ Tears of TFCC foveal insertion are common in patients with DRF and concomitant ulnar styloid base fractures. Based on the findings of this study, tear of TFCC foveal insertion seems to be also common in patients with DRF and concomitant ulnar styloid tip fractures. And also, DRUJ instability seems to be associated with a TFCC foveal tear independent of USF location.
