This study aimed to evaluate the short- and mid-term results of plica excision in patients with mediopatellar plica and associated cartilage degeneration. Seventy-six surgically treated patients with mediopatellar plica and associated cartilage degeneration at medial femoral condyle (MFC) and/or medial pole of patella were included. Patients were evaluated at baseline, at 6 weeks and 6 months after the operation for their clinical outcomes and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores. The frequency of all signs and symptoms, including all pain parameters, and WOMAC scores were significantly improved compared to baseline, at 6 weeks and 6 months after the operation (P < 0.017). Based on mean WOMAC scores, results of most patients were rated as excellent both at 6 weeks (88%) and at 6 months (94%). Surgical excision of mediopatellar plica associated with cartilage degeneration appears to result in substantial clinical improvement, thus it represents an effective treatment modality.

Objective: Synovial plicae are mesenchymal tissue remnants invaginating into the knee joint. Their classification is based on the location as lateral, mediopatellar, suprapatellar, and infrapatellar. Mediopatellar plica is commonly symptomatic.

Synovial plicae are thickenings of the synovial knee membrane; they are very frequent and often asymptomatic. However, they can become symptomatic due to idiopathic or secondary causes, like trauma and inflammation of the synovial tissue. Currently, synovial plicae are classified as infrapatellar, mediopatellar and suprapatellar.

Purpose: To evaluate whether mediopatellar plica and knee morphometric measurements obtained from magnetic resonance imaging (MRI) studies are associated with isolated medial patellofemoral osteoarthritis in young adults.
Methods: MRI studies from 60 patients with isolated medial patellofemoral osteoarthritis and 90 control patients with normal knee MRI studies were reviewed. The presence of mediopatellar plica, the presence of edema in the superolateral aspect of Hoffa's fat pad and suprapatellar fat pad, quadriceps and patellar tendinosis, and axial and sagittal alignment of the patellar and trochlear morphology were assessed using MRI.

There is a consensus that there is no overt anterior joint capsule in the knee. However, other anterior structures act in lieu of a joint capsule: the quadriceps tendon and patellar retinacular fibres. In the absence of a capsule, the synovium forms the suprapatellar pouch.

The present study aimed to investigate the expression of a neuropeptide of symptomatic mediopatellar plica (MP) to prove that there was a significant correlation between the expression of substance-P (SP) in MP and patellofemoral pain. The specimens of synovial plica were obtained by knee arthroscopy. Semi-quantitative analysis was used to investigate the expression of SP, and compared the innervation density of SP among the three groups: Blank control (asymptomatic plica), positive control (symptomatic plica with other injuries) and experimental (symptomatic plica without other injuries) groups by the paired t-test, one-way analysis of variance and Student-Newman-Keuls test in 60 patients.
