Anterior displacement of the tibial tuberosity in the treatment of XXXX patellae.

@entity1 @entity1844 @entity6081 @entity49 @entity158
Anterior displacement of the tibial tuberosity combined with shaving of the diseased cartilage was used as treatment for @entity1844 patellae in 32 knees in 28 consecutive @entity1 and in one @entity1 with @entity1844 femoris. The @entity1 were aged 17 to 57 years. One @entity1 had earlier sustained a serious injury to the ligaments of the knee, resulting in instability. All @entity1 except one were unfit for work before the operation. @entity6081 was noted in two knees and @entity49 occurred in three legs. The postoperative observation period varied from 8 months to 2 years and 10 months. In one knee the anterior displacement of the tibial tuberosity was not maintained. In lateral radiographs the anterior displacement of the tibial tuberosity in the other knees varied from 10 to 23 mm. The relief from @entity158 obtained by the operative treatment was estimated as good in all knees except three, which were unchanged. All @entity1 became fit for work and/or sport.
