So far, knee strain is the focus of research in many countries. Knee strain in fitness programs, at present, most of them are about the damage principle of some ligaments around the knee, and some problems of prevention and control. In this experiment, through the observation of the rehabilitation training of the equipment fitness system for the patella strain, the difference of the treatment effect of the patella strain was compared. Then we can find out a more factual and effective exercise method, and provide a new contrast with the rehabilitation treatment of patellar injury. We randomly divided some patients with knee injuries, such as patella, into two groups on average. The first observation group and the second control group were given rehabilitation training, and the athletes were given treatment and rehabilitation training for three months. During this period, all the athletes have undergone systematic exercises of equipment fitness, and have different rehabilitation training under the management of professional fitness coaches. Evaluating the balance and muscle strength of all athletes before and after the test in terms of pain activity, knee adduction and outward movement, calm state. The rehabilitation of knee injury was also evaluated and the data before and after the experiment were compared. The paired sample t was detected by ±s method, and the number of analysis was processed by analyzing. Conclusion before and after the experiment, tibial pain, joint movement, resting balance force, muscle tension and other indexes were analyzed and evaluated. There was no significant difference in the data before the experiment (p > 0.05). Compared with that before the experiment, it was improved greatly, with a significant difference (P < 0.01). There are also great improvements in the knee rehabilitation of basketball players. We also hope that the equipment fitness will be helpful to the patella injury after basketball.
