case_images: Radiographs done at this time did raise a suspicion of possible foreign body in notch area (Fig. 1).
case_images: Coronal (a) and axial (b) cuts of CT scan right knee lucidly delineating presence of foreign body measuring 15 x 6 mm in size situated near the base of anterior cruciate ligament in proximity with its tibial attachment site.

case_images: CT scan revealed hyperdense foreign body within the joint measuring approximately 15*6 mm situated anterior to lower one-third of anterior cruciate ligament (ACL) (Fig. 2).
case_images: (a) Shiny glass shard with jagged edges located closed to distal one-third of anterior cruciate ligament, (b) Fibrosis and hyperemia around the glass particle and near its tibial insertion site, (c) The fibrosis debrided with the shaver and integrity of anterior cruciate ligament assessed using a probe, (d) Pristine medial and lateral compartments with uninvolved and healthy articular cartilage.

case_images: Shiny glass shard was now clearly visualized near the base of ACL (tibial attachment site) (Fig. 3a). There was minimal fibrosis over distal part of ACL which was debrided using a motorized shaver post removal of the glass piece (Fig. 3b and 3c). To our surprise, fortunately, the rest of the joint was pristine with healthy medial and lateral compartments (Fig. 3d).
case_images: Images showing (a) glass fragment retrieved by grabber (b) measuring around 1.5 cm in size with sharp edges.

case_images: The particle was not freely mobile and was retrieved calmly with the help of grabber measuring roughly around 1.5 cm with jagged edges (Fig. 4a and b).
