The Epidemiological Analysis Of The326Cases Of Knee Joint Fractures Application Of Absorbable Cartilage Screw Analysis Curative Effect In The Treatment Of Osteochondral Fracture Of The Knee

Part1:The epidemiological analysis of the326cases of knee joint fracturesObjective:We collected the data of326cases of knee articular cartilageinjury, by studying the epidemiological and clinical characteristics,provide a basis for prevention diagnosis and treatment for knee soft bonefracture, to provide clinical reference for all kinds of operationtreatment of osteochondral fracture of the knee.Method:1collection of knee joint fractures in patients with clinical data (videorecord and operation record), the basic conditions of the patients.2each observation data analysis2.1The age distribution of patients with knee joint fractures2.2The gender distribution of patients with knee joint fractures2.3Knee joint fractures difference about side2.4different knee disease or injury occurrence and distribution of osteochondral fracture site2.5different knee joint disease or injury of bone cartilage fracture (aknee joint disease or injury of knee number/total knee number)Result.:Bone and cartilage of knee joint1,93.55%fracture patients ranging in age from20to49years old. In20-29and30-39age of patients is higher than those of other ages.2, the knee joint such as cartilage fracture patients, gender and the knee joint had no statistical difference.3, knee joint osteochondral fracture of the patella fracture patients, the inner side of the highest incidence rate, followed by the lateral femoral condyle, respectively46.86%and31.57%. Bone and cartilage of knee joint4,73.42%fracture patients with abnormal patellar tracking. Bone and cartilage of knee joint fracture of20.55%patients with ACL injury.Conclusion:there is no abnormal patellatracking patients, kneeosteochondral fracture, should be particularly careful, avoid the diagnosis and treatment of ligament injury of the knee joint omission. Part2:application of absorbable cartilage screw analysis curative effect in the treatment of osteochondral fracture of the kneeObjective:trauma operation methods for the traditional large, difficult toexamine and treat the full of intra-articular lesion, there is a bigtechnical difficulty. We use absorbable cartilage screw in the treatment ofknee joint fractures and the treatment results were retrospectively analyzed,and experience summary treatment experience.Method:1, the conventional operation mode after spinal anesthesia for furtherexamination examination in patients with knee joint stability andactivity, Q angle and patellar examinations in patients with patellar shiftdegree. Sterilized after arthroscopy, first, to further clarify thepatients with knee injury.1.1patients with severe abnormal patellar tracking for arthroscopic reduction patellar articular surface fracture is difficult, take the side incision of knee joint, the knee joint was layer by layer, exposure of the articular surface of the patella, patella articular surface fracture clotand hyperplastic lesion tissue clearance, the bone cartilage bone block reset, and then into the2-3medal cartilage in the direction vertical tothe articular surface of the nail as far as possible (absorbable screws),to ensure that the cartilage nail head buried layer of cartilage, confirmthe articular surface of the patella reset good. Flush joint cavity,according to the medial patellar ligament reconstruction.1.2combined with knee ligament and meniscus injury and fracture block for other parts of the knee joint can be given in arthroscopic fixation, first find the bone cartilage block free, place it in a relatively fixed position; and then the fracture clot and hyperplastic lesion tissueremoved, appropriate enhance bone slots to facilitate fracture reset;microscopic initial fracture reduction block, with small temporary Kirschner wire fixation after reduction, confirm the good, as far as possible into2-3pieces of cartilage in the direction perpendicular to the articular surface of the nail (absorbable screws), to ensure that thecartilage nail head buried in soft bone layer. Then, according to the condition of the ligament and meniscus repair.1.3Of2postoperative rehabilitation after knee brace immobilization. We give the knee0degrees2weeks fixation, second days after the start of unit four quadriceps isometric contraction, straight leg raising, pushing the patella training, third week and gradually increased movement, reaches90degrees around, during be related to physical therapy.3follow-up and statistical analysis of follow-up Lysholm score using to evaluate the function of knee joint.Results:the patients were followed up for3-12months after operation,bone union was obtained in3months, the joint activity recovered well.without obvious joint pain symptoms, Lysholm score (93.2±2.6)%, the excellent and good rate was94.6%.Conclusion:the treatment of osteochondral fracture has the advantages oflittle trauma, simple operation, firm fixation under arthroscopy cartilagenail. Patients with good functional recovery, clinical effect.
