Abstract:
Objective To analyze the relationship between the clinical features and the dysfunction and derangement of knee osteoarthritis(OA),in order to improve the understanding of knee OA.Methods Clinical data including symptoms,physical signs,X-ray,arthroscopical findings,pathologic changes,preopera-tive and postoperative diagnosis,treatment and curative effects from206post-arthroscopy patients with OA were analyzed retrospectively.Results The common physical signs were tenderness in knee,positive grinding test of patella,McMurray sign,fricative,muscular atrophy of quadriceps femoris,and stretch or flexion limita-tion.X-ray abnormalities were found as follows in decreasing freguency:bony hyperplasia,articular facet sclero-sis,osteoporosis,uneven articular surface,narrowing of joint space and loose bodies.Arthroscopical findings were as follows:synovial congestion and proliferation,hypertrophy or entrapment of fat pad,osteophyte,syn-ovial fold entrapment,stripping of cartilage,meniscal lesions,subchondral bone exposure,anterior cruciate lig-ament friction or obstruction,and loose bodies.The common diseases that liable to misdiagnosis preoperatively were synovial chondroma,anterior cruciate ligament impingement syndrome and meniscal lesions.The rate of excellent and good results after arthroscopic treatment was86.6%.Conclusion Hypertrophy and entrapment of fat pad,thickening and entrapment of synovial fold,stripping of cartilage,meniscal lesions,anterior cruciate ligament friction or obstruction,and loose bodies are the key factors that cause knee dysfunction in OA.The arthroscopic treatment is an effective supplement in treating knee OA.
