In the surgical treatments for the basketball players of Mitsubishi team of a women's Japan league, the operation for patellar pain has been achieved most frequently in our hospital. To know the actual state of their patellar pain, the direct examination and the roentgenographical measurement of sky-line view of the patella were done.
Of fourteen basketball players, five had patellar pain, and one of them was treated by operation. The values of Q-angle and of roentgenographical measurement (tilting angle and lateral shift) of players' were much as those of control group. Joint laxity was predominantly frequent in players. Patella pain in basketball players seemed not to be due to the malalignment and the subluxation of the patella. It is possible that joint laxity induces a source of patellar pain, but the problem of accurate evaluation of joint laxity remains.
