Outcomes After Repair of Subacute-to-Chronic Grade III Metacarpophalangeal Joint Collateral Ligament Injuries in the Lesser Digits Are Poor: Level 4 Evidence

Abstract

Injury to the metacarpophalangeal (MCP) joint collateral ligament of the lesser digits is less common than corresponding injuries in the thumb. Outcomes after thumb MCP joint collateral ligament repair are generally favorable. This study examines the outcome after primary repair of subacute-to-chronic grade III collateral ligament injuries of the MCP joints of the lesser digits. Our hypothesis was that the outcome after surgical treatment of these injuries is suboptimal.
