Twenty two pairs of menisci of which one meniscus was PAA treated and the other was left untreated (FF), were biomechanically analysed using a novel meniscus fixture. Prior to the testing, meniscus length was measured (a). Strain was measured and meniscal size was calculated after the application of a 200 N load (b and c). While keeping the strain constant for 45 min, the tissue starts to relax (d). On a subset of 8 menisci this testing was performed in 5 consecutive days (e). Two groups sharing the same character are not significantly different (p < 0.05)
