| ObjectivePatella cartilage bone fractures of the patella fracture is a special type of clinical rare. Patella bone fracture of articular cartilage fracture reduction and higher fixed, slightly misconduct will result serious complications, when the patella joint surface roughness level of more than 2-3 mm, may lead to the occurrence of traumatic arthritis. The objective is to maintain joint operation of the formation of the patella cartilage bone fracture treatment, should be to maximize the restoration of the articular surface morphology, and strive to make anatomical reduction fractures, joint surface smooth, given the more firmly fixed in the early activities of the knee and restore Function to prevent the occurrence of traumatic arthritis. Patella bone joint surface cartilage fracture reduction and poor, not smooth, easy to heal after a patellofemoral arthritis, such as joint fixed a long time, articular bone shavings, hematoma to deal with clean, joints can occur within the adhesion and hinder joint activities. Patella cartilage bone fracture treatment principle, firmly fixed in a reliable, smooth joint surface reduction, joint activities early. Patella cartilage bone fractures occurred in young people, because of its clinical manifestations not typical, X-ray films no specific signs of clinical easily lead to misdiagnosis and missed diagnosis and irreversibility patella femoral arthritis, tremendous impact on young people. This paper patella cartilage bone fractures in the diagnosis, surgical methods and efficacy were discussed. Patella cartilage on bone fractures in the literature of Chinese and Western Medicine retrospective study, and make diagnosis and treatment of fractures of the patella bone cartilage methods.MethodsOn February 2005 to December 2007 surgical treatment of 18 cases of patellar bone cartilage fracture clinical data analyzed. 10 males, female 8 cases, 7 cases left, right 11 cases. Botao wounding seven cases, out of five cases, sprains five cases, one case of accident injuries. Fresh fractures in 15 cases, 3 cases of old fractures, arthroscopic surgery in 8 patients, open reduction surgery in 10 cases. Shenqu encourage patients after joint initiative, quadriceps and hamstring isometric exercises and training over the patella. Arthroscopic surgery patients in accordance with or by reference to Lysholm knee score functional evaluation of its efficacy standards, open reduction and internal fixation of patellar fracture patients with a treatment evaluation criteria.ResultAll patients were 3 to 21 months (average 13.2 months) follow-up. Arthroscopic surgery patients with an average recovery time of five weeks, after three months on average Lysholm knee function score (91.7±2.3) points, after six months the average score (94.4±2.8) - All the Contralateral knees resume activity. Open reduction and internal fixation of bone surgery patients with an average healing time for eight weeks with patella fracture treatment standards, no pain, joint activities such as limited.ConclusionsOsteochondral fracture of the patella in accordance with the block size and injury time, using arthroscopy, endoscopic surgery or open reduction, application processing AO mini-screw osteochondral fracture of the patella, the results are satisfactory. Arthroscopic osteochondral fracture of the patella with surgical trauma small, easy to operate, reliable fixation and postoperative rehabilitation fast, fewer complications, such as benefits, can be found at the same time and combined treatment of intra-articular injury. AO using micro-fracture of titanium screw fixation blocks, accurate reduction surgery, articular surface formation, reliable fixation, shear stress fracture to heal, avoid or reduce the occurrence of traumatic arthritis. |
