**5.2 Rationale for using arthroscopic-assisted anatomic PLC reconstruction**

The rationale for using presented technique is a scientifically proved efficacy of anatomic PLC reconstructions in treatment of PLRI. Presented technique allows for a stepwise approach and management only this structure which has been damaged-PLT or FCL, or both. Whereas FCL reconstruction is obligatory in case of chronic lateral instability, in many patients the external rotation component of PLRI may be addressed with PLT tenodesis. However, when PLT femoral attachment is damaged or complete mid-substance tear occurs, anatomic PLT reconstruction is necessary.
