LCL and PLC occur mostly as a result of a blow to the anteromedial aspect of the knee, hyperextension or a varus force.  They are often combined with a cruciate ligament injury and can be very disabling.



Treatment will depend on the type of injury, time span and other associated injuries. 

Surgery is mainly indicated for complete avulsions of the LCL, rotatory instabilities and combined injuries. The procedure is either a repair or reconstruction of the LCL or PLC.  You will be in a brace for 6 weeks following the operation.  Rehabilitation with the physiotherapist is very important.
