3 Introduction Symptoms after meniscectomy : allograft meniscal transplantation Noyes et al. J Orthop Sports Phys Ther 2012 Lee et al. Sports Med Arthrosc 2012

4 Introduction Preoperative sizing length width Yoon et al. Am J Sports Med 2011

5 Introduction Preoperative sizing height? width /

6 Objectives Evaluate associations: - meniscal height X length and width - meniscal height X individual s anthropometric data - heights of the meniscal segments are associated with each other in the same meniscus

7 Methods Cross-sectional and observational study MRI scans of the knees of 25 pacients (50 knees) Knee Surgery Group at Santa Casa de Misericórdia de São Paulo

8 Methods WIDTH LENGTH

9 Methods HEIGHTS

10 Results associations between the heights of the meniscus (p < 0,05) correlation values were generally low (r < 0.5) poor correlations

11 Discussion Meniscal height: independent measure should not be predicted from the meniscal length and width biomechanical studies: importance of the meniscal height for the biomechanical functions of the meniscus on load protection

12 Conclusions Poor correlations: Meniscal height X length and width Meniscal height X individual s anthropometric data Heights of the meniscal segments are associated with each other in the same meniscus
