Pain‑related risk factors after arthroscopic minimally invasive treatment of meniscus injury of knee joints

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.

Minimally Invasive Bone-Patellar Tendon-Bone Graft Harvest Is Associated With Less Frequent Anterior Knee Pain at Rest Than Hamstring Graft Harvest After Anterior Cruciate Ligament Reconstruction at the 1-Year Follow-Up

“…Other factors that may contribute to knee pain include the arthroscopic procedure itself. 18 Our study supports the literature on the double-incision BPTB technique; the results of which show less anterior knee pain than a technique that harvests the graft using a longer single incision. 6 …”

Prediction of lateral meniscal tear in patients with Schatzker II tibial plateau fractures based upon preoperative X-ray: a retrospective study

“…The second level meniscus injury usually involves a partial tear of the meniscus that remains in its normal position, this may require further conservative treatment, such as physiotherapy or anti-in ammatory drugs, to aid recovery. The third level meniscus injury indicates that the meniscus has been completely torn, and a third level meniscus injury usually requires surgical repair, usually performed using knee arthroscopic techniques [24]. In this study, we used arthroscopy for intraoperative exploration.…”

Effects of Different 0.2% Ropivacaine Infusion Regimens for Continuous Interscalene Brachial Plexus Block on Postoperative Analgesia and Respiratory Function After Shoulder Arthroscopic Surgery: A Randomized Clinical Trial

“…25 Surgical site and techniques are independent risk factors that affect the severity and duration of postoperative pain. 26 To ensure a homogenous group for analysis, the type of surgery in our study was restricted to arthroscopic rotator cuff surgery.…”
