Objective To study the effect of arthroscopic intercondylar fossa angioplasty on the ability of neuromuscular control of the knee joint in elderly patients with knee osteoarthritis (KOA). Methods Between June 2012 and March 2013, 20 elderly patients with KOA and in accordance with inclusion and exclusion criteria underwent arthroscopic intercondylar fossa angioplasty (operation group), and 20 healthy elderly people served as control group. There was no significant difference in age, height, weight, and body mass index between 2 groups (P>0.05). The proprioception capability (using passive regeneration test at measurement angles of 15, 30, and 60°) and quadriceps mobilization [including maximum voluntary contraction (MVC), central activation ratio (CAR), and activation deficit (AD)] were measured to avaluate the neuromuscular control of the knee;the Lysholm score was used to evaluate knee function. The above indexes were measured to assess the knee neuromuscular control and recovery of joint function in patients of operation group at 3, 6, and 9 months after operation. Results Compared with the control group, MVC, CAR, and Lysholm scores were significantly decreased, and the AD and passive knee angle difference were significantly increased in operation group (P<0.05) before operation. With the time after operation, the Lysholm score, CAR, and MVC increased gradually, and the AD and the passive knee angle difference decreased gradually. There was no significant difference in the indexes between 2 groups at 9 months after operation (P>0.05). Conclusion Arthroscopic intercondylar fossa angioplasty can relieve ACL pressure, abrasion, and impact, which will recover the ability of neuromuscular control, increase proprioception and quadriceps mobilization capacity, and improve the joint function.
