Abstract

To assess the clinical outcomes of a group of patients who underwent arthroscopic infrapatellar plica (IPP) excision and to determine, whether the IPP was symptomatic or not, to identify the symptoms or signs in the patient's clinical presentation and to study the correlations between arthroscopic findings and patient's clinical presentation. A retrospective clinical study. We studied all the patients undergoing arthroscopic resection of symptomatic infrapatellar plica without other intraarticular abnormality at our department from February 1996 to April 2001. Fourteen patients with isolated IPP and with regular follow-up intervals were included in the study. Arthroscopy findings, preoperative magnetic resonance imaging (MRI) findings, and clinical presentation were correlated. The mean duration of follow-up was 36 months with a range of 24-60 months. The IPP was found to be in fenestra pattern in seven patients, separate (cordlike) pattern in five patients and vertical septum pattern in two patients. IPP in all patients was excised with a powered instrument. Two patients were rated as excellent, ten patients as good and two patients as poor results. All the patients were documented with pain, popping or snapping with flexion and extension, giving way and swelling. There was no correlation between IPP type and MRI findings with being symptomatic (P > 0.05). It was found that IPP type was not a prognostic factor. Infrapatellar plica should be considered as a potential cause of knee pain with probable MRI imaging and no other evidence of internal derangement. We recommend close correlation with the clinical symptoms and exclusion of other internal derangement before suggesting infrapatellar plica as a sole cause for knee symptoms.
