Abstract：BACKGROUND:Low back pain is a normal syndrome in department of orthopedics. Moreover, most patients are consisted with knee joint degeneration. Through the conception of“knee-spine syndrome”has been proposed for a long time, the study which focused on low back pain and lumbar facet joints and degenerative knee is not quite easy to find. <br> OBJECTIVE:To summarize and analyze articles involved in the low back pain syndrome of smal arthrogenous degeneration-induced lower back pain combined with knee osteoarthritis. <br> METHODS:We retrieved PubMed database and China National Knowledge Infrastructure for related articles published from January 1998 to August 2014. The key words were low back pain, knee osteoarthritis, lumbar facet joint, total knee replacement, block treatment, non-fusion techniques, inflammatory factor, drug treatment. Repeated articles and some low connected researches were excluded. <br> RESULTS AND CONCLUSION:A total of 157 articles were retrieved, and final y 60 articles were included. Present studies showed that smal arthrogenous lower back pain could promote osteoarthritis progress. In pathophysiology, tumor necrosis factor-αand interleukin-1β, along with matrix metal oproteinase might play a significant role. As for the biomechanics, the meaning of angle in facet joint, with the inclination angle affected to osteoarthritis is the centre of study. As for clinical treatment, conventional closed treatment in the early stage can identify the source of the pain. For the patients with mild disease, fixation and functional exercises can be used to delay disease progress. In advanced patients, surgical treatment could restore functions and lessen pain.
