Abstract
We present the case of a 48-year-old male patient in whom a Grade IV chondral lesion, measuring less than 1 cm2 in surface area, was incidentally observed during the arthroscopic excision of a volar ganglion at the level of the metacarpophalangeal (MCP) joint of the right third digit.
During follow-up consultations, poor clinical progression was noted, with the patient experiencing pain and functional limitation, along with recurrent joint effusions, although maintaining a full range of motion. Given these findings, we decided to perform an arthroscopic joint preservation surgery.
We conducted a revision arthroscopy. Initially, we performed a new synovectomy and debridement of the chondral lesion until the subchondral bone was exposed. Subsequently, we carried out nanofractures (1 mm in thickness and 9 mm in depth) manually using the A2C nanofracture system (up to 15° of angulation), simultaneously implementing a collagen matrix Chondro-Gide® (A2C).
