Preface
We extend our appreciation to ISAKOS for providing sponsorship and to
Springer for the editorial leadership for this book on the menisci. This text-
book was a collaborative project between the Sports Medicine and Knee
Committee members and their research staff. The authors of this textbook
certainly have a passion in trying to promote preservation of the menisci. As
surgeons, it appears that the one factor that we can effect to prevent osteoar-
thritis more than any other is to perform a meniscus repair when it is possible.
Thus, this textbook aims to review the different types of meniscus tears, those
types of meniscus tears that are repairable, and the benefits that can be seen
from repairing them.
We anticipate that this work will prove beneficial to surgeons worldwide.
In the future, we believe that further biologic augmentation of meniscus
repairs should stretch the indications for meniscal repairs even further com-
pared to the types of tears that we repair commonly. We certainly hope that
this textbook proves to be beneficial both for the arthroscopist in training and
for those at advanced levels of sports medicine practice.

Bibliography ........................................................... 7 The medial meniscus has a semilunar shape of
fibrocartilage localized between the medial fem-
oral and medial tibial condyle [8]. The medial
meniscus covers up to 60 % of the articular sur-
face of medial tibial condyle [4] and helps with
the loading distribution in medial compartment.
In 2015, Śmigielski et al. [17] proposed a new,
anatomical division of medial meniscus into five,
uneven anatomical zones (Fig. 1.1). Within each
zone, there is similar anatomy and identical liga-
ments attaching the meniscus to surrounding struc-
tures. Therefore, not only anatomy but also technique

of suturing may need to differ between zones.
