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.

Review Meta AnalysisEvolution of total hip arthroplasty in patients younger than 30 years of age: A systematic review and meta-analysis.
While surgical technique and implant technology for total hip arthroplasty (THA) has improved over the years, it is unclear whether recent progress has translated to improved clinical outcomes for young patients. The goal of this study is to determine trends in (1) indications, (2) surgical technique (3) clinical and radiographic outcomes, and (4) survivorship for THA in patients younger than 30 years of age. ⋯ Advances in surgical technique and technology have served to improve implant longevity. Surprisingly, subjective clinical scores showed no significant improvement over time, suggesting that early iterations of THA were extremely successful.

Increased time from injury to surgical repair in patients with proximal hamstring ruptures is associated with worse clinical outcomes at mid-term follow-up.
Prior studies of hamstring tendon tears have reported varied findings on whether increased delay from injury to surgery is associated with worse outcomes. The purpose of this study was to determine whether increased time from injury to surgical repair is associated with worse clinical outcomes in patients with proximal hamstring ruptures. ⋯ This study found that acute repair performed within 6 weeks of injury appears to yield improved PROs compared to chronic repair. These data highlight the importance of timely and accurate diagnosis of proximal hamstring ruptures and early operative intervention for surgical candidates.

Correction of ankle varus deformity using patient-specific dome-shaped osteotomy guides designed on weight-bearing CT: a pilot study.
Dome-shaped supramalleolar osteotomies are a well-established treatment option for correcting ankle deformity. However, the procedure remains technically demanding and is limited by a two-dimensional (2D) radiographic planning of a three-dimensional (3D) deformity. Therefore, we implemented a weight-bearing CT (WBCT) to plan a 3D deformity correction using patient-specific guides. ⋯ Level 5 case series.
