Abstract
Pain-related risk factors after arthroscopic minimally invasive treatment of meniscus injury of knee joints were explored. Altogether 42 patients (conservative group), 40 patients (open group) and 46 patients (minimally invasive group) who received conservative treatment or arthroscopic knee surgery at the Quwo County People's Hospital were selected. The clinical effects of patients in the three groups at 24 weeks after treatment were observed. The knee joint activity, the knee injury and osteoarthritis outcome score (KOOS), Lysholm knee joint function score, VAS pain score and WOMAC score were recorded before treatment, at 24 weeks after treatment and at 2 years after treatment. Complications were also recorded. The related risk factors of postoperative pain were analyzed. There was no significant difference between the short-term efficacy of conservative treatment and that of surgical treatment (P>0.05); however, the long-term improvement effect of the surgical treatment on knee joint function and pain was better (P<0.05). The short-term and long-term effects of arthroscopic surgery were close to those of the open surgery. Arthroscopic surgery had a good long-term improvement effect on knee joint function and pain (P<0.05), and the incidence of postoperative pain was low (P<0.05). The results of logistic multivariate regression analysis manifested that WOMAC score, articular cartilage injury, time of postoperative weight bearing <1 week, no postoperative cold compress and open knee surgery were independent risk factors that affected postoperative pain (P<0.05). In conclusion, arthroscopic minimally invasive treatment has a good effect on patients with meniscus injury of knee joints who fail conservative treatment. Articular cartilage injury, postoperative weight bearing, cold compress and type of operation are independent risk factors that affect postoperative pain. Clinicians should bring patient attention to the prevention of meniscus injury and further improve the efficacy of treatment.
