Results of total hip arthroplasty in patients who have rapidly progressive hip disease: a systematic review of the literature.
Rapidly progressive hip disease is a rare condition characterized by rapid joint space narrowing (>2 mm in 1 year), chondrolysis and destruction of the femoral head. Although the etiology and pathogenetic mechanism is unclear, subchondral insufficiency fractures in the setting of physiologically weakened bone has recently been implicated as the primary insult. The standard of care has been total hip arthroplasty; however, there is a theoretical risk that the disease process may continue, placing the prosthesis at risk. In order to determine the clinical outcomes and implant survivorship in this population, a systematic search of the literature was conducted. Midterm (mean: 5 years) results following total hip arthroplasty demonstrated mean good-to-excellent clinical results (clinical hip scores >80 points) and a 3% revision rate, making this a valuable treatment option for patients who have rapidly progressive hip disease. The underlying disease process does not appear to compromise implant longevity.
