Abstract Purpose To evaluate the effect of patient participation in arthroscopic partial meniscectomy (APM) on rehabilitation and patient satisfaction. Methods A total of 86 patients of traumatic longitudinal vertical meniscus tears, between January 2017 and December 2020 at the First Affiliated Hospital of Zhejiang Chinese Medical University, met the inclusion and exclusion criteria. The patients in the intraoperative participation group (n = 33) were awake and could watch the screen during APM and communicate with the surgeon in the surgery; patients who underwent APM in the traditional mode were classified as the traditional group(n = 53). The differences in exercise adherence, the Knee Injury and Osteoarthritis Outcome Score (KOOS) and satisfaction at follow-up were compared. In the intraoperative participation group, the mean age of the patients was 26.97 ± 5.63 years and the follow-up time was 25.12 ± 6.23 months. In the traditional group, the mean age of the patients was 29.21 ± 5.29 years and the follow-up time was 25.08 ± 6.70 months. Results The intraoperative participation group reported a better result in exercise adherence (78.79% VS 50.94%, p = 0.012). As secondary outcomes, Patients in the intraoperative participation group demonstrated better scores on the KOOS domains of pain (79.80 ± 6.38 VS 76.26 ± 5.33, p = 0.007), Symptoms (59.41 ± 5.27 VS 56.74 ± 5.97, p = 0.038), and QOL (65.91 ± 10.72 VS 60.26 ± 9.34, p = 0.012), as compared to these in the traditional group. There were no significant differences in the KOOS domains of Sport (72.88 ± 8.20 VS 72.64 ± 7.70, P = 0.892), and ADL (89.47 ± 3.50 VS 87.87 ± 4.50 p = 0.085). what’s more, in the intraoperative participation group, the results of satisfaction (96.97% VS 81.13%, p = 0.025) were also significantly better. Conclusion The mode of participation of patients during APM can improve patients’ exercise adherence, reduce pain, improve symptoms and improve patients’ satisfaction as well as the quality of life. More work is needed to develop this mode further.

Abstract Background The purpose of this study was to reveal the clinical history and physical and magnetic resonance imaging (MRI) findings of patients with an inverted-type discoid lateral meniscus (DLM) tear compared with those with a symptomatic and torn discoid meniscus without inverted tear patterns. Materials and methods Between 2014 and 2016, 12 patients underwent arthroscopic partial meniscectomy for an inverted-type DLM tear (inverted group). We age-matched these patients with 12 controls who were extracted from many normal DLM tear cases in the same period (non-inverted group). The assessment items were traumatic history with the onset of pain, the mean duration between the appearance of symptoms and surgery, preoperative knee range of motion (ROM), positive findings on the McMurray test, knee locking or catching, and characteristic MRI findings. These items were compared between the two groups using χ2 and Student’s t-tests. Result All patients in the inverted group had clear trauma with the onset of pain during sports or daily life activities, and 7 of the 12 patients with a non-inverted type of DLM tear had clear trauma. There was a significantly higher rate of traumatic history in the inverted group than in the non-inverted group (P = 0.03). The mean duration between the appearance of symptoms and surgery, preoperative knee ROM, positive findings on the McMurray test, and knee locking or catching were not significantly different between the inverted and non-inverted groups. On MRI, the diagnosis ratio of DLM was significantly higher in the non-inverted group (9/12 cases) than in the inverted group (3/12 cases, P = 0.04). Nine of the 12 inverted-type patients had the characteristic findings of an inverted-type DLM tear, including a duplicated or enlarged posterior horn and blunting of the inner rim, on the sagittal plane of an MRI. Conclusion Patients with inverted-type DLM tears had clear trauma and infrequently had the characteristic MRI findings that are observed in patients with normal DLM tears. Physicians should suspect that an inverted-type DLM tear is present during diagnosis and focus on the posterior horn to find the inverted sign on the MRI sagittal plane. Level of evidence Level III.

Abstract Background Arthroscopic surgery is a common treatment for knee osteoarthritis (OA), particularly for symptomatic meniscal tear. Many patients with knee OA who have arthroscopies go on to have total knee arthroplasty (TKA). Several individual studies have investigated the interval between knee arthroscopy and TKA. Our objective was to summarize published literature on the risk of TKA following knee arthroscopy, the duration between arthroscopy and TKA, and risk factors for TKA following knee arthroscopy. Methods We searched PubMed, Embase, and Web of Science for English language manuscripts reporting TKA following arthroscopy for knee OA. We identified 511 manuscripts, of which 20 met the inclusion criteria and were used for analysis. We compared the cumulative incidence of TKA following arthroscopy in each study arm, stratifying by type of data source (registry vs. clinical), and whether the study was limited to older patients (≥ 50) or those with more severe radiographic OA. We estimated cumulative incidence of TKA following arthroscopy by dividing the number of TKAs among persons who underwent arthroscopy by the number of persons who underwent arthroscopy. Annual incidence was calculated by dividing cumulative incidence by the mean years of follow-up. Results Overall, the annual incidence of TKA after arthroscopic surgery for OA was 2.62% (95% CI 1.73–3.51%). We calculated the annual incidence of TKA following arthroscopy in four separate groups defined by data source (registry vs. clinical cohort) and whether the sample was selected for disease progression (either age or OA severity). In unselected registry studies the annual TKA incidence was 1.99% (95% CI 1.03–2.96%), compared to 3.89% (95% CI 0.69–7.09%) in registry studies of older patients. In unselected clinical cohorts the annual incidence was 2.02% (95% CI 0.67–3.36%), while in clinical cohorts with more severe OA the annual incidence was 4.13% (95% CI 1.81–6.44%). The mean and median duration between arthroscopy and TKA (years) were 3.4 and 2.0 years. Conclusions Clinicians and patients considering knee arthroscopy should discuss the likelihood of subsequent TKA as they weigh risks and benefits of surgery. Patients who are older or have more severe OA are at particularly high risk of TKA.
