전방십자인대 재건술후 재활운동프로그램이 무증상환자의 보행분석에 미치는 영향

초록

Subjects of this study were 16individuals(13male and 3female) who had been inpatients(recipients of ACL reconstructive surgery) at a university hospital from April of 2005 to June of 2006 as a result of sports injury or accidents. Average age of study subjects was 28.31±10.27(year), height 172.12±7.25(cm), and weight 71.38±16.08(kg), and rehabilitation therapy program was conducted under the prescription of specialist who conducted the reconstructive surgery. Rehabilitation exercise program was conducted in a total of 5 stages. Following surgery, compression bandages were placed and ice compress was given to decrease swelling. Two days after surgery,1) Peak torque of knee extensor at 60o/sec was 11.06±28.64ft-lbs, the affected side was 41.34±18.53ft-lbs(p<.05), and knee flexor showed 53.57±16.62ft-lbs and 32.08±13.42ft-lbs respectively(p<.05). The unaffected side of knee extensor at 180o/sec was 72.46±18.95ft-lbs, the affected side was 34.68±17.87ft-lbs(p<.05), and knee flexor showed 43.38±12.78ft-lbs and 29.31±13.75ft-lbsft-lbs respectively(p<.05). In the case of flexor muscle, when compared to the normal side, loss of the affected side improved to 20.7%(six months after surgery) from 30.5%(three months after surgery) at 60deg/sce, and from 26.8% to 17.3% at 180deg/sec. In the case of extensor muscle, when compared to the normal side loss in the affected side improved from 118.3% to 89.2%, three months after surgery at 60deg/sec and from 93.6% to 68.7% at 180deg/sce. In both flexor and extensor muscles, improvement made 6months following surgery was more statistically significant than improvement made 3months following surgery(p<.05). 2) The maximum swing phase flexion angle for the affected knee joint was 52.48±2.76° and that of the normal knee joint was 48.74±3.07° which showed an increase in the flexion angle of 3.74°, and the difference was statistically significant(p<.032). The result of conducting the study on asymptomatic patients who received reconstructive surgery due to ACL injury revealed significant enhancement in both flexor muscles and extension muscles, and also displayed increase in maximum flexion in swing phase. This signifies that rehabilitation exercise program in addition to range in motion exercise has a positive effect on recovery of proprioceptive sensation. Therefore, it can be stated that more than static knee joint stability, stability of kinetic knee joint in movement is an important element in returning to activity, and it can be suggested that rehabilitation program following ACL reconstructive surgery that enhances functional stability and muscular function of the knee joint is a necessary factor in returning to sports.
