Abstract:
Objective To investigate clinical value of diagnostic blocking test of knee joint for diagnosis and treatment of knee osteoarthritis complicated with degenerative lumbar disease. Methods Thirty-two outpatients of knee osteoarthritis complicated with degenerative lumbar disease were selected from September 2003 to June 2004. There were 10 males and 22 females with an average of 71.5 years old (range, 55 to 78 years). After routinely sterilizing and drapping aseptic towel, knee joint was placed in 60?-90? flexion position, and punctured at the medial or lateral patellar tendon parallellizing with the superior edge of tibial plateau. Fluidity was draw-off, 10 ml lidocaine(1% concentration) and 1 ml Diprospan were injected. All patients were performed diagnostic blocking test of knee joint. Let outpatients record the symptoms of lower limb through inquiry papers at 1 hour, 1 day, 2 days, 1 week after injection. The VAS pain score of knee joint was recorded before injection and 1 week after injection. Furtherly consulted the outpatients and recorded the VAS pain score of knee joint 1 week after injection. Then determine treatment procedure after integrative evaluation. Results The pain around the knee joint obviously decreased in 21 patients (lenitive rate, 75.6% to 100%), moderately decreased in 8 patients(lenitive rate, 51.3% to 73.5%), mildly or less decreased in 3 patients(lenitive rate, 0% to 34%). After integrative evaluation, 22 patients were performed with TKA, 3 patients were performed with lumbar spine operation, and 7 patients were treated conservatively. The results of operation treatment were satisfactory. The sensitivity of diagnostic blocking test was 86%. Conclusion Diagnostic blocking test of knee joint is a kind of simple, safe and effective differential method for patients of knee osteoarthritis complicated with degenerative lumbar disease, and also a kind of objective observation method for prognosis, and provide necessary reference criteria for operation sequence of lumbar spine and knee joint.
