Familial recurrent dislocation of patella with autosomal dominant mode of inheritance

Recurrent dislocation of the patella is considered to be a manifestation of generalized joint laxity. An autosomal dominant mode of inheritance was previously suggested in a few instances; however, male-to-male transmission has not yet been reported. We report a recurrent dislocation of the patella occurring in five generations of one family with male-to-male transmission and without generalized joint laxity.
