ABSTRACT
A 44-year-old man presented with lipoma arborescens of the right shoulder, associated with a rotator cuff tear. MRI revealed villous proliferations with signal intensity of fat on all pulse sequences. At surgery, this bursa was found to contain moderately yellow cloudy fluid without fat globules. Histological examination of the lesion showed subsynovial accumulation of mature fat cells.

The authors have made a retrospective study of 90 total knee arthroplasties performed through a lateral approach in knees with a valgus deformity superior or equal to 10 degrees. The mean function score increased from 35.9 to 73.2 postoperatively; the mean knee score increased from 60.2 to 93.6. Radiological evaluation of the mechanical angle (HKA) showed 16 degrees of valgus deviation preoperatively versus only 1.5 degrees of valgus post-operatively. A strict operative technique using a lateral approach in severe valgus knee deformity makes it possible to reproducibly achieve joint stability with good mobility and a neutral mechanical axis in total knee arthroplasty.
