Abstract
The medial collateral ligament (MCL) is made up of different components and spans the medial aspect of the knee. With injuries the superficial or deep and posterior components may be involved. A variety of conditions including MCL bursitis, medial osteoarthritis, medial cellulitis, medial bursitis, medial meniscal cyst, meniscocapsular separation, and retinacular tear may present with high signal surrounding the MCL fibers and simulate an MCL tear.

Summary
The medial collateral ligament (MCL) is made up of different components and spans the medial aspect of the knee. With injuries the superficial or deep and posterior components may be involved. Key-words: Knee, ligaments and menisci – Knee, MR. The MCL is covered by the superficial medial fascia (Fig. 1). The MCL itself is deep to this fascia and is composed of an anterior part and posterior part. The anterior part is loosely attached to the meniscus, and shows a superficial band and deep meniscofemoral and meniscotibial bands (Fig. 2). The MCL is in continuity with the medial retinaculum patellae. The posterior part of the MCL does not show the layered appearance of the anterior part, and in this region only one bandlike structure is apparent [1, 2]
