BACKGROUND:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold which has been constructed in previous experiments has good biocompatibility and biodegradability and generates non-toxic degradation products.
OBJECTIVE:To observe the vascularization of rabbit renal microvascular endothelial cels co-cultured with poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold.
METHODS:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold having a three-layer structure (layer of bone/bone and cartilage interface layer/layer of cartilage) was prepared by solvent casting/particle leaching method. The renal microvascular endothelial cels at passage 3 were seeded onto the scaffold of bone layer. The proliferation of the renal microvascular endothelial cels growing on the scaffolds was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, the growth of cels in the scaffold was observed by hematoxylin-eosin staining under electron microscope after 10 days.
RESULTS AND CONCLUSION:The integrated osteochondral scaffold had a clear appearance of three-layer structure, which had closed connections between the three layers. Porous bone layer was visible as wel as uniform and interlinked pores, and the porosity was 78%. The renal microvascular endothelial cels seeded onto the scaffold proliferated wel and presented a three-dimensional growth after 10 days of co-culture, but there were no cels on the interface layer. Cels which adhered and grew between the pores of the bone layer were observed through hematoxylin-eosin staining. Cels showed a luminal-like structure growing on the scaffold with the porous structure, but they did not grow into the interface layer of bone and cartilage.

OBJECTIVETo explore the clinical effects of internal fixation with lag screws plus an anti-sliding plate for the treatment of Hoffa fractures of the lateral femoral condyle.

METHODSFrom May 2006 to May 2014, 17 patients with Hoffa fractures of the lateral femoral condyle were treated with lag screws plus an anti-sliding plate. There were 13 males and 4 females, ranging in age from 27 to 59 years, with a mean of 32.5 years. All the fractures were fresh and closed fractures. According to the Letenneur's classification, 8 cases were type I, 4 cases were type II, 5 cases were type III. All the patients had no injuries of the cruciate ligament and the another part of the knee. Operative incision and fracture healing time were observed, knee joint function was evaluated by Letenneur system and HSS standard.

RESULTSThe patients were followed up from 10 to 24 months with a mean of 14.6 months. All incisions achieved primary healing, and no internal fixation breakage, malunion, femoral candyle necrosis, deep vein thrombosis of lower extremity were found. Fracture healing time was from 4 to 9 months with an average of 4.7 months. According to Letenneur's functional assessment, 10 patients got an excellent results, 4 good, 3 fair. Total HSS score was 91.1 +/- 4.7 on average,15 cases obtained excellent results, 2 good.

CONCLUSIONInternal fixation with lag screws and an anti-sliding plate can result in excellent effects for Hoffa fractures of the lateral femoral condyle. The key to a successful surgery is an anatomic reduction and rigid fixation of the fracture.
