The aim of this study is the investigation of the clinical results after third generation autologous chondrocyte implantation in the knee in a follow-up over three years post-operation. Our primary focus is on the effects of this procedure on children and adolescent patients as there is a lack of knowledge regarding the clinical outcomes in children/adolescents in particular when compared with adults. ⋯ This study showed that third generation autologous chondrocyte implantation is a suitable method for the treatment of full cartilage defects in children and adolescents.

Surgical treatment of persistent non-union of the humeral shaft is a complex situation because of the risk of failure and surgery-related complications. The primary objective of this study was to evaluate clinical and radiological results of a continuous series of persistent non-union treated with plating and bone grafting. The secondary objective was to expose factors contributing to the failure of prior bone union attempts. ⋯ Plating and autologous bone grafting resulted in union in only 75 % of persistent non-union of the humeral shaft. The persistent nature of the humeral shaft non-union could be attributed to deviating from validated rules for surgical treatment and/or the presence of a surgical site infection.

Beginners usually need increased punctures and dozens of fluoroscopy in learning transforamimal percutaneous endoscopic lumbar discectomy (tPELD). Navigator-assisted spinal surgery (NASS) is a novel technique that could induce a definite trajectory. The retrospective study aimed to investigate the impact of a definite trajectory on the learning curve of tPELD. ⋯ Definite trajectory significantly reduced the operation time, preoperative location time, puncture-channel time, and fluoroscopy times of tPELD by beginners, and thus reshaped the learning curve of tPELD and minimized the radiation exposure.

Surgical treatment of acetabular fractures in elderly people is challenging. The main aim of this study is to evaluate retrospectively the indications, results and the complications of simultaneous open reduction and internal fixation (ORIF) and acute total hip replacement (THR) in the management of displaced acetabular fractures. ⋯ ORIF and simultaneous THR is a good option for the treatment of certain types of acetabular fractures particularly in elderly population.

Randomized Controlled Trial
Effects of multi-site infiltration analgesia on pain management and early rehabilitation compared with femoral nerve or adductor canal block for patients undergoing total knee arthroplasty: a prospective randomized controlled trial.
The aim of this study was to combine intra-articular and peri-articular with wound infiltration analgesia (multi-site infiltration analgesia, MIA) for patients undergoing total knee arthroplasty (TKA) and compare its pain management and early rehabilitation effect with the commonly used nerve block including adductor cannel block (FNB) and femoral nerve block (ACB). ⋯ ACB was not inferior to FNB on pain control, but it was better on early mobilization. However, MIA that combine intra-articular and peri-articular with wound infiltration analgesia after TKA was more effective on pain control at rest, with better efficacy on early rehabilitation and easier to perform when compared with these commonly used nerve block. We recommended our MIA for pain relief and fast rehabilitation after TKA.
