Progress on the treatment of recurrent anterior dislocation of shoulder with bone defect / 中国骨伤

Recurrent anterior dislocation of shoulder with bone defect is one of the common diseases of shoulder joint. How to effectively repair glenoid bone defect and reduce recurrence rate of shoulder dislocation is a problem that clinicians focus on. Bone grafting could stimulate bone, promote bone regeneration and bone remodeling, and restore the normal anatomical structure of glenoid. Among them, Bristow-Latarjet procedure is a classic operation for recurrent shoulder dislocation. Latarjet procedure could repair larger glenoid bone defects, but with higher surgical skills for surgeons;autogenous iliac grafting is the first choice for revision once Latarjet procedure failed;osteochondral grafting (autogenous and allogenous) has certain advantages in reconstructing original articular surface and preventing joint degeneration, but autologous osteochondral grafting may cause secondary injury, while immune rejection is difficult to avoid for allogenous osteochondral grafting. With the improvement of composite materials, and the mechanism of bone regeneration and remodeling, as well as the advantages and disadvantages of bone grafting, tissue engineering technology may become an effective method for the treatment of glenoid bone defect in the future.

Follow-up study on autogenous osteochondral transplantation for cartilage defect of knee joint / 中国骨伤

OBJECTIVE@#To evaluate clinical effect of autologous osteochondral transplantation in treating localized knee cartilage defects.@*METHODS@#Fifteen patients with knee cartilage defects were treated by autologous osteochondral transplantation from January 2007 to January 2008, including 8 females and 7 males, aged from 23 to 45 years old. Preoperative and postoperative KSS score at 10 years were compared.@*RESULTS@#All patients were followed up for 10.0 to 10.7 years, with an average of(10.2±0.3) years. Clinical score of KSS was improved from 38.86±4.09 to 85.07±2.19 at 10 years after operation(0.05). All patients had no other complications.@*CONCLUSIONS@#Through long-term follow-up of patients with cartilage defect in knee treated by autologous bone cartilage transplantation showed that this method could effectively improve function of knee joint and alleviate pain. So it is an effective method for repair of osteochondral defect.
