“…The expression of IL1-ß mRNA, MMP-3 mRNA and MMP-3 in the medial plica of the knees with early stage knee OA suggests that medial plica and its interplay with its facing medial femoral condyle might play an important role in the pathogenesis of medial compartment OA knee [10]. A three-dimensional dynamic nate element model has demonstrated that the close relationship and possible high contact pressure between a brotic medial plica and medial femoral condyle during knee motion might be a cause of cartilage damage on the medial femoral condyle [12]. These ndings support the fact that using arthroscopic release to eradicate brotic medial plica could be effective in symptom relief, and it might even modify the disease process of OA knees [14], [15].…”

Background The effectiveness of arthroscopic treatment for knee osteoarthritis (OA) has been subject to debate. This study presents an innovative concept of arthroscopic management for knee OA and investigates its clinical outcome.Methods An arthroscopic cartilage regeneration facilitating procedure (ACRFP) to eliminate medial abrasion phenomenon and decompress the patello-femoral joints was performed on 693 knees of 411 patients with knee OA, mean age 60 years (34-90). The Knee Society score (KSS) and the knee injury and osteoarthritis outcome score (KOOS) were used for subjective outcome study. Roentgenographic changes for all cases and magnetic resonance imaging (MRI) variations for twenty randomly selected cases were evaluated for objective outcomes. Results There were 634 knees in 369 patients (93.7%) available with more than 3 years of follow-ups (mean 40 months, SD 9). The overall subjective satisfactory rate was 91.1%. The KSS and all subscales of the KOOS improved statistically. Reversal of the degeneration process of cartilage was observed in 80.1% of the whole series (radiographic outcome) and in 72.2% of the 18 randomly selected cases (one-year MRI outcome study). Gender and OA severity were related to subjective outcomes. Age, body mass index (BMI), pre-operative hyaluronic acid injection, OA severity, and the type and severity of the medial plica are important predictors of radiographic outcomes. An analysis of failed cases reaffirmed the need for early ACRFP and skillful post-operative care. Conclusion ACRFP is an effective treatment for knee OA. If performed in time, it can satisfy most patients and might modify their degeneration process.

“…The cartilage delamination in our patient was likely due to repeated injury and impingement from the stiff medial parapatellar plica; increasing Young's modulus of the plica is associated with greater contact pressures on the underlying cartilage [12]. Synovial plicae may cause injuries to the underlying cartilage through a combination of compression, friction, and shear forces [13] and are associated with an increase in underlying articular cartilage lesions when present in a joint [7, 14, 15].…”

We report a case of a chondral delamination lesion due to medial parapatellar plica friction syndrome involving the medial femoral condyle. This mimicked a torn medial meniscus in clinical and radiological presentation. Arthroscopy revealed a chondral delamination flap, which was debrided. Diagnosis of chondral lesions in the knee can be challenging. Clinical examination and MRI have good accuracy for diagnosis and should be used in tandem. Early diagnosis and treatment of chondral lesions are important to prevent progression to early osteoarthritis.

“…The topographic changes of the margins of these plicae during knee motion were recorded by fluoroscopy and analyzed. Based on the findings of these pilot studies, a three-dimensional dynamic finite element model was constructed and used to investigate the magnitudes of the cyclic pressures acting on the cartilage of the medial femoral condyles by different types of medial plicae with various Young's moduli [12]. Young's modulus of the plica was found to be ranging from 10 to 110 MPa and has positive correlation with patient's age [11].…”

“…The maximum contact pressures of all simulation scenarios occurred when the knees moved beyond 50°of flexion. When the Young's moduli of medial plicae were set greater than 60 MPa, all types of plicae would elicit contact pressures greater than 10 MPa on the medial femoral condyles which are damaging to the cartilage [12].…”
