The single-suture technique for anterior cruciate ligament graft preparation provides similar stability as a three-suture technique: a biomechanical in vitro study in a porcine model.
Numerous techniques have been described for the tibial-sided graft preparation in anterior cruciate ligament (ACL) reconstruction. The use of less suture material for graft preparation is thought to improve ingrowth and to reduce the risk for infection. At the same time, the suture construct should be strong enough to resist the surgeon's pull during tensioning of the transplant. ⋯ The presented single-suture tendon graft preparation resisted to smaller failure loads than the conventional three-suture technique. However, no failures in the suture-tendon interface were seen and the failure loads observed were far beyond the tension forces that can be expected intraoperatively. Hence, the single-suture graft preparation technique may be a valuable alternative to the conventional technique.

Human umbilical cord blood-derived mesenchymal stem cell implantation for osteoarthritis of the knee.
This study aimed to investigate the clinical outcomes after human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSC) implantation for medial compartment (MC) osteoarthritis of the knee. ⋯ hUCB-MSC implantation regenerated cartilage satisfactorily and showed satisfactory clinical outcomes in patients older than 60 years who had MC osteoarthritis.

Total hip arthroplasty following acetabular fracture: a clinical and radiographic outcome analysis of 67 patients.
Total hip arthroplasty (THA) is a challenging option for the treatment of posttraumatic arthritis due to acetabular fractures. ⋯ The decrease of the interval between injury and arthroplasty was associated with increasing patient age (p = 0.001) and surgical treatment of the acetabular fracture (p = 0.04). Complex fracture patterns were accompanied by acetabular bone defects more often than simple patterns (p = 0.03). Overall, arthroplasty due to posttraumatic osteoarthritis after acetabular fracture resulted in decreased overall survival rates and poorer clinical outcome as compared to primary arthroplasty.

The entry point of intramedullary tibia cutting guide should vary according to the individual tibia morphology in TKA.
In total knee arthroplasty (TKA) using the intramedullary tibial cutting guide (IMTCG), the positioning of the IMTCG is important for accurate tibial bone resection. The aim of this study was to evaluate the ideal entry point of IMTCG and affecting radiologic factors. ⋯ The ideal entry point of IMTCG should vary according to the individual tibial morphology.

Corrective osteotomies of femur and tibia: which factors influence bone healing?
Corrective osteotomies of the lower limb are standard procedures in orthopedic surgery. Still, there is only limited research on factors affecting bone healing after osteotomies. We hypothesize that especially the location of the osteotomy, smoking status and BMI affect bone healing. ⋯ Smoking status and the localization of the osteotomy on femur and tibia (diaphysis vs. metaphysis) are significantly correlated with bone healing duration. In line with current literature emphasizing the detrimental effect of smoking on bone healing, our findings should encourage surgeons to think twice about the indication to perform osteotomies on smokers. Furthermore, if applicable, osteotomies should be performed in the metaphyseal areas of femur and tibia.
