Show morePurpose The purpose of this study was to determine and compare the percentage of completely healed meniscal tears after arthroscopic repair combined with anterior cruciate ligament reconstruction (ACLR) for the different vascular zones of the meniscus. Methods PubMed, Embase, Web of Science, Cochrane library and Emcare were searched on 19 May 2020 for articles reporting healing rates after arthroscopic meniscal repair with concomitant ACLR for the different meniscal vascular zones as assessed by second-look arthroscopy. Data on meniscal tears were extracted as located in zones 1, 2 or 3, according to the Cooper classification. Studies were graded in quality using a modified Newcastle-Ottawa Scale. Pooled analyses were performed utilizing a random-effects model. Meta-analyses were performed using R version 3.6.2 and SPSS statistical software version 25.0. The study was registered with PROSPERO (ID:CRD42020176175). Results Ten observational cohort studies met the inclusion criteria, accounting for 758 meniscal tear repairs in total. The pooled overall proportion of healing was 78% (95% CI 72-84%). The mean weighted proportion of healing was 83% (95% CI 76-90%) for studies (n = 10) reporting zone 1 tears and 69% (95% CI 59-79%) for studies (n = 9) reporting zone 2 tears. No study reported healing rates for zone 3 tears. The pooled overall odds ratio was 2.5 (95% CI 1.00-6.02), indicating zone 1 tears as 2.5 times more likely to heal than zone 2 tears. Conclusion This study demonstrates that meniscal tears localized in vascular zone 1 were more likely to heal than those in zone 2. Show less

Show moreThis thesis is about meniscal tears and repair in the first part and on meniscal allograft transplantation in the second part. An overview of meniscal function, effects of meniscal deficiency and (historical) treatment options are given.The first part is further focussed on meniscal reparability based on MRI findings and evaluates clinical survival of meniscal repair.The second part of this thesis is focuses on meniscal allograft transplantation. Clinical results of both open and arthroscopically assisted MAT are presented. A Dutch meniscal patient reported outcome measure (PROM)is translated and culturally adapted. Show less
