Intra-articular Large Ossicle Associated to Osgood-Schlatter Disease

Wonchul Choi et al. Cureus. .

Abstract

Osgood-Schlatter disease (OSD) is known as a self-limiting condition but surgical excision of the ossicles may be required in adults resistant to conservative treatments. The ossicle associated to OSD is generally small and located outside the joint near the tibial tubercle; however, large or intra-articular ossicle has been reported rarely. Here, we report an unusual case of OSD with a separated, large-sized ossicle that protruded into the knee joint and treated by arthroscopy-assisted excision of the ossicle.

Keywords: knee arthroscopy; osgood -schlatter disease; ossicle.

Figures

Figure 1
Figure 1. Lateral plain radiographs of both knees.
(A) A large osseous lesion (arrow) is seen at the infrapatellar area of the right knee. (B) An osseous body (arrowhead) of equivalent size was partially fused to the hypertrophied tibial tuberosity of the left knee.
Figure 2
Figure 2. Right knee magnetic resonance images.
(A) A large ossicle with heterogenous signal intensity (arrow) and a Baker’s cyst (asterisk) are seen on axial image. (B) From T1-weighted sagittal image, the ossicle (arrow) is separately located inside the infrapatellar fat pad. (C) T2-weighted sagittal image shows inflammation of patellar tendon (solid arrow) and bone marrow edematous change of anterior tibia plateau (dotted arrow). (D) Small separated ossicle (arrow) was found inferior to the large ossicle from coronal image.
Figure 3
Figure 3. Right knee arthroscopy findings.
(A) The ossicle was covered by soft tissue (asterisk). (B) After removing the soft tissue by mechanical shaver, the ossicle (asterisk) is exposed.

Figure 4. Gross appearance of the excised ossicle.
The ossicle was fragmented during surgery.
Figure 5
Figure 5. Intraoperative fluoroscopy finding.
Complete removal of the ossicle was confirmed (arrow).
Figure 6
Figure 6. Histopathology finding.
The hematoxylin and eosin staining showed osteocartilaginous tissue without distinct cartilage cap, suggestive of ossicle associated to Osgood-Schlatter disease.
