The Journal of Bone & Joint Surgery British Volume, 2001•boneandjoint.org.ukWe have studied whether the state of the articular cartilage at the time of rotational
acetabular osteotomy for dysplasia of the hip affects the outcome 2 to 5.5 years after surgery.
Arthroscopy in 57 patients (59 joints) at the time of the operation showed grade-0 changes in
seven, grade-1 in nine, grade-2 in 17, grade-3 in 14 and grade-4 in 12 joints, according to
the classification of Outerbridge. There was radiological evidence of the progression of
arthritis in four joints which were classified at arthroscopy as grade 4. Stepwise regression …

We have studied whether the state of the articular cartilage at the time of rotational acetabular osteotomy for dysplasia of the hip affects the outcome 2 to 5.5 years after surgery. Arthroscopy in 57 patients (59 joints) at the time of the operation showed grade-0 changes in seven, grade-1 in nine, grade-2 in 17, grade-3 in 14 and grade-4 in 12 joints, according to the classification of Outerbridge. There was radiological evidence of the progression of arthritis in four joints which were classified at arthroscopy as grade 4.
Stepwise regression analysis showed that damage to acetabular or femoral articular cartilage significantly affected the progression of arthritis. We conclude that the short-term results of successful rotational acetabular osteotomy for dysplasia are affected by the state of the articular cartilage.
