Plantar plate deficiency is the major cause of instability of the metatarsophalangeal joint. As the joint subluxates dorsally, the lumbrical is tethered on the medial side of the joint by the deep metatarsal ligament and becomes a deforming force for the development of crossover toe deformity. Release of the lumbrical is needed to achieve adequate medial soft-tissue release. Plantar plate tenodesis has been described to correct the deformity by suturing the plantar plate to the extensor digitorum longus tendon. The purpose of this Technical Note is to incorporate the technique of arthroscopic release of the lumbrical tendon into the technique of plantar plate tenodesis.

Open resection of a large lipoma requires a large incision that may result in disfigurement from the scar. Endoscopic resection of the lipoma can have better cosmetic results. However, piecemeal removal of the lipoma has the disadvantage of fragmentation of the tumor before it can be determined whether it is benign or malignant. In this Technical Note, the technical details of endoscopically assisted en bloc resection of an anterior knee lipoma are described. This can provide a whole-block specimen for histologic examination.
