ABSTRACT
In the typical radiology practice, magnetic resonance (MR) imaging of the postoperative
knee is a common and almost daily occurrence. Postoperative patients present with
a wide array of complaints including persistent or recurrent knee pain and instability.
A thorough knowledge of the commonly performed procedures along with the normal postoperative
appearance and potential postoperative complications will ensure that the radiologist
provides an optimal evaluation of the postoperative MRI. This article reviews some
of the most common arthroscopic procedures performed on the knee including ligament,
meniscal, and articular cartilage procedures. A description of the most common procedures
is provided along with a discussion of the expected postoperative appearance of the
knee. The most common complications and reasons for recurrent symptoms are discussed.
MR imaging techniques are reviewed including the various options available for evaluating
the postoperative meniscus. A thorough discussion is provided regarding the advantages
and disadvantages of the use of conventional MRI versus direct and indirect MR arthrography
in the setting of prior meniscal surgery.
