“…Similar to the results of other studies [11,28,31], we also found that DLM type has no signi cant effect on postoperative e cacy. This may be why no signi cant differences were found in the incidence of articular cartilage lesions and postoperative discoid meniscus morphology among different types of discoid meniscus [15,17] [7].…”

“…Thus, females are more susceptible to cartilage lesions and osteoarthritis [20] and being female is associated with poor postoperative clinical outcomes. However, Chen et al [11] and Kose et al [28] found that sex has no signi cant effect on postoperative result of DLM; this nding may be related to the small sample size in their study (n=39 cases, n=48 cases, respectively).…”

“…For symptomatic DLM, numerous studies have found that the earlier the age of onset is, the shorter is the duration of symptoms (especially <12 months) and that the earlier the surgical intervention is performed, the better is the prognosis [5,11,31,38,49]. We found that the age of onset <25 years, especially <14 years (P < 0.001, OR = 37.069; 95% CI: 7.822-55.147), and the symptoms duration <24 months (P < 0.001, OR = 3.254; 95% CI: 1.855-5.703) are advantageous for postoperative e cacy.…”

“…Although the overall postoperative clinical outcomes of symptomatic DLM are acceptable [11,17,38], the outcomes still differ among individuals, possibly as a result of the diversity in patient characteristics and treatments [31]. Recently studies have reported several factors that in uence postoperative effect in symptomatic DLM, but the sample sizes used in these studies are uneven, and the results are inconsistent [10][11]19,28]. The present research independently analyses 14 possible in uences, including gender, body mass index (BMI), and other factors, in a larger series of patients with the goal of identifying the factors that in uence postoperative outcome in patients with symptomatic DLM and thereby guiding clinical application.…”

Background: Due to its abnormal morphology and ultrastructure, discoid lateral meniscus (DLM) is prone to tear and degeneration, leading to clinical symptoms. Arthroscopy is the main treatment for symptomatic DLM; however, postoperative outcomes vary widely due to the effects of diverse factors. This research aims to explore the factors influencing postoperative outcomes of symptomatic DLM. Methods: Patients with DLM who underwent arthroscopic surgery at our hospital from 9/2008 to 9/2015 were enrolled according to the inclusion and exclusion criteria. Fourteen variables, including sex, body mass index (BMI) and other variables, were chosen as factors for study. Knee function was assessed using the International Knee Documentation Committee (IKDC) score. Univariate analyses (Mann-Whitney U test or Kruskall-Wallis rank sum test) and multivariate analyses (ordinal logistic regression) were used to identify the factors that influenced postoperative outcomes. P<0.05 was considered statistically significant.Results: A total of 502 patients, including 353 females (70.3%) and 149 males (29.7%), were enrolled. The median IKDC score postoperatively (87.4; range, 41.4~97.7; IQR, 14.6) was higher than that preoperatively (57.6; range, 26.9~ 64.9; IQR, 9.7) (P<0.001). Male sex was predictive of a higher IKDC score (P=0.023, OR=1.702). Compared with BMI ≥25 kg/m2, <18.5 kg/m2 was associated with better IKDC score (P=0.026, OR=3.016). Contrasting with age of onset ≥45 years, ≤14 years (P<0.001, OR=20.780) and 14~25 years (P<0.001, OR=8.516) were associated with better IKDC score. In comparison with symptoms duration>24 months, IKDC scores for patients with symptoms duration ≤1 month (P=0.001, OR=3.511), 1 ~ 6 months (P < 0.001, OR = 3.463) and 6 ~ 24 months (P < 0.001, OR = 3.254) were significantly elevated. Compared to Outerbridge grade III ~ IV, no injury (P<0.001, OR=6.379) and grade I (P=0.01, OR=4.332) were associated with higher IKDC score.Conclusions: Arthroscopic treatment of symptomatic DLM is safe and effective, but its clinical efficacy is affected by many factors. Specifically, male sex, BMI < 18.5kg/m2, age of onset < 25 years (especially < 14 years) and symptoms duration < 24 months are conducive to good postoperative outcomes. However, combined articular cartilage injury (Outbridge grade≥2) reduces postoperative effect.

Introduction The postoperative effect of arthroscopy in the treatment of symptomatic discoid lateral meniscus (DLM) varies greatly among individuals. Therefore, this study aims to investigate the factors affecting the postoperative outcomes of symptomatic DLM. Materials and methods According to the inclusion and exclusion criteria, patients with symptomatic single-knee DLM who underwent arthroscopic surgery at our hospital from 9/2008 to 9/2015 were included. Retrospectively collected 16 factors probably affecting postoperative outcomes. The Ikeuchi grade system was used to evaluate the knee joint function. Univariate analysis was performed by Kruskal–Wallis rank-sum test or Mann–Whitney U test, and multivariate analysis by ordered logistic regression. P < 0.05 was considered statistically significant. Results A sum of 502 patients was included, including 353 females (70.3%) and 149 males (29.7%). Difference between preoperative and postoperative Ikeuchi grade was statistically significant (P < 0.001). Female was bad to obtain a good Ikeuchi grade (P = 0.009, OR 0.458). Outerbridge grade (P = 0.018, OR 0.638) was negatively correlated with Ikeuchi grade. BMI (P = 0.001, OR 0.875) and work intensity (P = 0.020, OR 0.611) were inversely correlated with Ikeuchi grade. Age of onset (P < 0.001, OR 0.956) and symptoms duration (P < 0.001, OR 0.988) were negatively correlated with Ikeuchi grade. Besides, compared to total meniscectomy, meniscoplasty with a repair was an unfavourable factor for Ikeuchi grade (P = 0.044, OR 0.245). Conclusions With the increase of BMI, work intensity, age of onset, duration of symptoms, and the severity of cartilage lesion, the postoperative results become worse. Moreover, female and meniscoplasty with repair are risk factors for the postoperative outcomes.
