1After arthroscopic cleanup application of sodium hyaluronate treatment of elderly patients with knee osteoarthritisAbstract Objective To investigate the arthroscopic cleanup after application of sodium hyaluronate in the treatment of knee osteoarthritis clinical effect method the Court since 2006, 86 cases of 95 patients with osteoarthritis of the knee arthroscopic synovial clean up, rinse postoperative intra-articular injection of sodium hyaluronate and then observe the clinical effect results were followed up for 3 to 24 months, an excellent rate of 86.3%. conclusion arthroscopic synovial clean up after intra-articular injection of sodium hyaluronate can effectively improve joint function, pain relief is an effective treatment for osteoarthritis of the knee, are summarized below. Words osteoarthritis of the knee arthroscopic treatment of sodium hyaluronate Knee Osteoarthritis is the most common in the older age groups, male and female disease. Increased significantly because China has 2entered the aging society in the incidence of knee osteoarthritis clinical manifestations: knee pain, swelling, joint plot fluid, articular cartilage damage, the destruction of the periarticular structures, joint cavity size and shape, ranging from loose bodies and bone hyperplasia. previous physiotherapy treatment, surgery, taking non-steroidal anti-inflammatory drugs, hormones, but the effects are less than ideal. Arthroscopic line synovial debridement their trauma, quicker recovery, fewer complications, and more and more used in the treatment of senile knee osteoarthritis paper arthroscopic synovial cleanup , rinse, postoperative intra-articular injection of sodium hyaluronate in treating osteoarthritis of the knee in clinical research. 1 Materials and Methods 1.1 General Information The group of 86 cases of 95 knee 47 knee, the left and right side of the 39 knee bilateral in 9 cases, 32 males and 54 females, aged 45 to 74 years, with an average of 63.5 years of age, duration of 6 months to 10 years Case Selection diagnostic criteria according to Altman 1, based on symptoms, signs, X-ray and MRI 3examination, while excluding other joint diseases diagnosed in this group of patients had varying degrees of quadriceps atrophy, knee swelling recurrent, flexion and extension limited functionality, up and down stairs or squatting knee pain significantly worse. radiation and MRI revealed a lip-like proliferation around the tibiofemoral joint and the patellofemoral cartilage bone sclerosis, osteophyte formation around the patella, tibia intercondylar the spine becomes sharp, joint space narrowing, there may be knee valgus deformity of the knee joint cavity visible loose bodies of varying size and shape. Surgical patients supine on the surgical bed, limb flat on the surgical bed and knees 90 , taking infrapatellar medial approach placed arthroscopic the suprapatellar bursa patellofemoral joint lateral tibiofemoral gap intercondylar fossa gap in the order observed in the medial tibiofemoral line the joint cavity comprehensive inspection, intra-articular lesions. placed in the appropriate surgical instruments within anterolateral arthroscopic under direct vision, to remove 4cartilage soft loose bodies, debris, osteophyte and knee cavity completely removed within the joints with inflammation of the synovial tissue, cleaning of a torn meniscus in the small area of the cartilage the exfoliation line microfracture processing, and finally washed with 1000 ml of physiological The saline lavage intra-articular, intra-articular surgery placed suction drainage bandaged. 3.24 hours to pull out the drainage tube, two days after isometric quadriceps and limb straight leg raising functional training, after three days knee flexion functional training. Floating patella test was negative after a week joint cavity without significant effusion row intra-articular injection of sodium hyaluronate 20 mg injected once a week, five weeks for a course such as intra-articular effusion is more feasible knee ultrasonic or ultrashort wave therapy twice daily every 30 minutes to be fluid absorption before knee injection of sodium hyaluronate therapy. 1.2 Results 86 patients was 3 to 24 months of 5follow-up, and a variety of symptoms and signs were significantly improved, excellent in 59 knees, good in 23 knees in 13 knees, good rate of 86.3%, the evaluation standard 2. Effect is divided into excellent, good, fair, poor.
