“…MRI is more useful to rule out other intra-articular lesions as the cause of knee pain. Different rates of identification of imaging of the plica are probably because anatomic studies are able to detect a plica that is extremely thin and may be beyond the resolution of imaging [9].…”

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.

“…However, this anomaly can be detected by tracing from the anterior horn of the medial meniscus to the ACL on thin serial sections of T2-weighted images. An infrapatellar plica is similar to AIMM, with a curvilinear appearance anterior to the ACL on sagittal T2-weighted images (7). However, the origin of the infrapatellar plica does not attach to the anterior horn of the medial meniscus but to Hoffa's fat pad or the inferior pole of the patella, which can be confirmed on MR images and arthroscopic examination.…”

Anomalies of the medial meniscus are rare and difficult to diagnose clinically. Among these anomalies, anomalous insertion of the medial meniscus into the anterior cruciate ligament is rare. Most of the reported cases had no relation to clinical symptoms and were found incidentally during arthroscopy. We report a rare case of anomalous insertion of the medial meniscus into the anterior cruciate ligament with a brief review of the literature.

“…22 It is well known and understood in the knee. 4,8,10,12,13,15,17,18 Usually, a plica is a normal anatomic structure unrelated to knee pain. It can become symptomatic after a traumatic event, resulting in inflammation, fibrotic tissue proliferation, and tensile changes in the plica.…”
