**2. Indication**

Possible indications for the extraarticular procedures around the knee are; lateral release for painful bipartite patella, excessive lateral pressure syndrome, and recurrent dislocation of the patella (Maeno et al., 2008,2010), bursectomy for prepatellar bursa, and medial patellofemoral ligament (MPFL) reconstruction. It can be expanded to any other extraarticular works around the knee.
