The Plica: Is a New Aetiological Factor in the Knee Osteoarthritis?

Calcific mediopatellar plica: a case report

“…The worldwide arthroscopic series by Güney et al [8] Sakakibara [6] and Dandy [7] did not report any calcification of MPP. Although studies have shown that MPP causes chondral pathology, [1,[8][9][10] to our knowledge, there are no published reports that MPP could be calcified. Mediopatellar plica is often encountered during knee arthroscopy [11,12] We found no data on radiologic reports of patients found to have MPP during knee arthroscopy, in the literature.…”

“…[1] Arthroscopic surgical excision of calcific MPP with cartilage degeneration is important in clinical treatment. In the literature, chondromalacia, grades II-III, was found in the medial femoral condyle of most patients with MPP, and this occurs because of the presence of plica.…”

“…In the literature, chondromalacia, grades II-III, was found in the medial femoral condyle of most patients with MPP, and this occurs because of the presence of plica. [1,8,14] Therefore, the period between the time when the complaints first begin and arthroscopic plica excision directly affects the success of treatment and patient satisfaction. Our patient had symptoms for two years whereas and developed mechanical symptoms in the last six months which may be secondary to calcified MPP.…”

“…One of the common reasons for cartilage degeneration developing in the medial femoral condyle and medial patella is the presence of MPP. [1] The formation of a synovial compartment in the knee joint is a quite complex process in the embryologic period. A synovial gap forms in the 12 th week of gestation as a result of involution and absorption of synovial connective tissue.…”
