This study reviews 34 of 37 original patients who were reviewed in 1981 after previously undergoing percuta neous lateral retinacular release. Short-term satisfac tory results regarding reduction of pain and prevention of dislocation were maintained on this second followup (average, 48 months). With this increase in postopera tive time, patients with recurrent subluxation developed an increase in patellar slipping. Patients with chondro malacia and degenerative joint disease are less suited for long-term treatment. Long-term problems occurred in 1 of 34 patients (3%).
