We report the very rare case of an 8-year-old boy who accidentally fell on the ground, causing the lead of a pencil to penetrate his left knee joint cavity. After radiographic diagnosis, the pencil was removed by a physician at a private clinic and the boy was referred to our department for further evaluation. We performed arthroscopic retrieval of the pencil lead through standard arthroscopic portals without an accessory portal. Postoperatively, the patient had a quick recovery without problematic sequelae.

Arthroscopic rotator interval closure has been advocated to supplement the stabilization provided by thermal capsulorrhaphy for glenohumeral instability. However, no basic science study has examined the separate and combined effects of thermal capsulorrhaphy and rotator interval closure on the multiplane laxity of the glenohumeral joint. The purpose of this study was to measure the effects of isolated and combined thermal capsulorrhaphy and rotator interval closure on anterior, posterior, and inferior glenohumeral joint laxity in a cadaveric model. ⋯ When treating glenohumeral instability with arthroscopic techniques, rotator interval closure may enhance stability to a greater degree than thermal capsulorrhaphy without its associated risks.
