Abstract

Surgery is the treatment of choice for recurrent dislocation of the patella and many proposed operations can conveniently be grouped into three headings: transposition medially of the quadriceps pull mechanism (Hauser), installment of medial checkrein, either proximal or distal to the patella (Campbell) and patellectomy (West and Sotto Hall). Two cases of the dislocation observed in the young men are reported here, in which the authors performed an operation consisting of Hauser method and in addition the medial checkrein utilizing semitendinosus tendon. The results were successful in both cases, with complete restoration of the knee function.
