Objective To observe the effect of high-energy laser combined with stepped intervention strategy in patients with meniscus injury.

Methods A total of 87 patients with meniscus injury were selected as research subjects. According to the random number table method, they were divided into control group (n=44) and observation group (n=43). After admission, patients in both groups were electively treated with arthroscopic surgery. The control group received step-by-step nursing intervention, and the observation group received high-energy laser intervention on the basis of the control group. All patients were intervened continuously for 8 weeks. The limb pain assessed by Visual Analogue Scale (VAS) 1 day and 3 days after operation, the first time out of bed after operation, the hospitalization time and hospitalization expenses were observed, and knee function (Lysholm knee score) 1 day before operation and 8 weeks after operation and the occurrence of postoperative complications were compared between the two groups.

Results The VAS scores of both groups at 3 days after operation were lower than those at 1 day after operation, and were lower in the observation group when compared with the control group (P < 0.05); the first time out of bed, hospitalization time and hospitalization expenses in the observation group were 5.00 (5.00, 6.00) d, 6.00(5.00, 7.00) d and (12.20±1.20) thousand CNY, respectively, which were shorter than 6.00 (5.00, 8.00) d, 7.00 (6.25, 8.00) d and (12.80±1.40) thousand CNY. At 8 weeks after operation, the Lysholm knee of the control group and the observation group scored (74.87±4.12) and (82.25±4.54), respectively, which were higher than those of the first preoperative day, and the Lysholm knee score in the observation group was higher than that of the control group (P < 0.05). There was no statistically significant difference in the incidence of postoperative complications between the two groups (P>0.05).

Conclusion High energy laser combined with stepped intervention strategy for rehabilitation of patients with meniscus injury can reduce the degree of postoperative limb pain, shorten the early time out of bed and hospitalization time, reduce hospitalization expenses and promote the recovery of knee function of patients.
