Fig. 1A —32-year-old man with chondrolysis of shoulder after arthroscopy.
Preoperative T1-weighted axial (A) and axial STIR (B) MR images
of shoulder show normal articular cartilage (arrows) and subchondral
marrow signal intensity.

Fig. 1C —32-year-old man with chondrolysis of shoulder after arthroscopy.
T1-weighted axial (C) and axial STIR (D) images 2 years after
surgery show extensive joint space narrowing (long arrow) and loss of
normal articular cartilage on both sides of joint with cortical irregularity
and patchy areas of change in signal intensity in subchondral marrow
(short arrows) consistent with subchondral sclerosis and marrow edema
involving osseous glenoid process and, to lesser extent, humeral head.

Fig. 2A —19-year-old man with chondrolysis of shoulder after arthroscopy.
T2-weighted axial (A) and coronal STIR (B) images show superior
labral anteroposterior tear (arrow, B) that extends
posteriorly to involve posterior labrum (arrow, A). Articular
cartilage and subchondral marrow of both osseous glenoid process and humeral
head are normal.

Fig. 2C —19-year-old man with chondrolysis of shoulder after arthroscopy.
Axial (C) and coronal (D) T1-weighted images obtained 11 months
after surgery show joint space narrowing (long arrow) and loss of
articular cartilage with extensive subchondral sclerosis and marrow edema
(short arrows) diffusely involving osseous glenoid process and, to
lesser degree, medial aspect of humeral head.

Fig. 3B —18-year-old man with chondrolysis of shoulder after arthroscopy.
Follow-up anteroposterior radiograph 6 months after surgery shows extensive
narrowing (long arrows) of joint space. Extensive subchondral
sclerosis is present, and subchondral cyst formation (short arrows)
involves medial aspect of humeral head and osseous glenoid process.
