Surgical treatment for different types of dislocations of patella viz. (i) habitual, (ii) recurrent, (iii) congenital, and (iv) high riding patella is described. Satisfactory results were obtained by release of tight lateral structured alone (vastus lateralis, iliotibial band and lateral intermuscular septum, lateral patellar retinaculum and occasionally of rectus femoris) in habitual dislocations of patella. Construction of a check-rein or plication of the lax medial patellar retinaculum was considered unnecessary. Surgicap procedures for recurrent, congenital and highriding patellar dislocations are recommended.
