PurposeTo investigate the potential factors associated with the prevalence of meniscal repairMethodsPatients who received partial menisectomy or meniscal repair in our institution from Jan 2015 to Dec 2019 were included in current study. The inclusion criteria were (1) meniscus tear treated using meniscetomy or repair, (2) with or without concomitant anterior cruciate ligament reconstruction, (3) not multiligamentous injury. Demographic data, including sex, age, body mass index (BMI), injury-to-surgery interval and intra-articular factors such as the location of injury, medial or lateral, ACL rupture or not and the option of procedure (partial meniscetomy or repair) were documented from medical records. Univariate analysis consisted of chi-square. Multivariate logistic regression was then performed to adjust for confounding factors.Results592 patients including 399 males and 193 females with a mean age of 28.7 years (range from 10 to 75 years) were included in current study. In the univariate analysis, male (p=0.002), patients aged 40 years or younger (p<0.001), increased weight (p=0.010), Posterior meniscus torn (0.011), concurrent ACL ruputure (p<0.001), lateral meniscus (p=0.039)and early surgery (p<0.001) were all associated with the prevalence of meniscal repair. However, After adjusting for confounding factors, we found that age (OR, 0.35; 95% CI, 0.17 - 0.68, p=0.002), ACL injury (OR, 3.76; 95% CI, 1.97 – 7.21, p<0.001), side of menisci (OR, 3.29; 95% CI, 1.43 – 7.55, p=0.005), site of tear (OR, 0.15; 95% CI, 0.07 – 0.32, p<0.001), and duration of injury (OR, 0.46; 95% CI, 0.28 – 0.82, p=0.008) were associated with the prevalence of meniscus repair. ConclusionsMeniscal tear in aged patients especially those with concomitant ACL injury is likely to be repaired. Additionally, in order to increase the prevalence of repair and slow down progression of OA, the surgical procedure should be performed within two weeks after meniscus tear especially when the tear is located at lateral meniscal posterior.Study DesignCase-control study; level of evidence, 3.

PurposeTo investigate factors associated with the consumption of a large number of sutures during arthroscopic meniscus repair procedures.MethodsAll patients who received meniscal repair, with or without concomitant anterior cruciate ligament (ACL) reconstruction, in our hospital from January 2015 to December 2019 were included in the current study. Demographic data (sex, age, body mass index (BMI), and injury-to-surgery interval) and surgical data (the site of the tear, side of the meniscus, presence of an ACL rupture or not and the number of sutures) were retrospectively collected from our medical records. The number of sutures was divided into two groups (1–2 sutures versus > 2 sutures). The stitching process was implemented through an all-inside technique using a meniscal repair device (Fast-Fix; Smith & Nephew). According to the length and stability of the meniscal tear, one to seven sutures were used. Univariate analysis consisted of chi-square tests. Multivariate logistic regression was then performed to adjust for confounding factors.ResultsA total of 242 patients, including 168 males and 57 females, was finally included. In the univariate analysis, we found that those patients who underwent meniscus repair within one month after meniscus tear were more likely to need fewer sutures than those who underwent surgery more than one month after injury (70/110 versus 59/115, p = 0.062). In total, 75/109 (68.8%) lateral meniscal tears were repaired with fewer sutures than medial (34/72, 47.2%) and bilateral meniscus injuries (20/44, 45.4%; p = 0.003). In the multivariate analysis, we found that the duration of injury (OR, 2.06; 95% CI, 1.16–3.64, p = 0.013), presence of an ACL injury (OR, 3.76; 95% CI, 1.97–7.21, p < 0.001) and the side of the meniscus (OR, 0.31; 95% CI, 0.14–0.65, p = 0.002) were associated with the number of sutures used during meniscal repair procedures.ConclusionsPatients who underwent meniscal repair within one month after meniscus tear, especially lateral menisci tears, were more likely to need fewer sutures.Study DesignCase-control study; level of evidence, 3.
