“…However, most authors advise conservative treatment in the first instance, but arthroscopy and meniscectomy may be a choice of treatment for persistent symptoms. 2,4,7,9,12,13 Similar to the literature, the primary approach in our case was conservative. Surgery was not planned in our case due to the absence of persistent pain and decreased range of motion disturbances.…”

Discoid OssificationMagnetic resonance imaging a b s t r a c t Meniscal ossification, or bone formation within the substance of the meniscus, is a rare entity. Magnetic resonance imaging allows the unequivocal diagnosis of a meniscal ossification. We aimed to present a case of discoid meniscal ossification, which is quite rare, with the emphasis on imaging findings.Copyright © 2014, Delhi Orthopaedic Association. All rights reserved. IntroductionMeniscal ossification is mature lameller and cancellous bone containing fatty bone marrow surrounded by hyaline cartilage within the substance of meniscus. 1e3 Discoid meniscal ossification is exceedingly rare. Imaging is required to confirm the diagnosis and to assess the meniscal integrity. Standard radiographs and magnetic resonance imaging (MRI) have been reported useful in the diagnosis of meniscal ossification. 4 We aimed to present a case of discoid meniscal ossification with the emphasis on imaging findings. Case reportA 42-year-old women presented with pain in the left knee joint lasting for nine months. The pain was intermitten in nature. There was no history of recent trauma or any other relevant past history. Physical examination showed a moderately painful swollen joint without any restriction of movement. Upon admission, no pathological findings were found at the patellofemoral joint or periarticular ligamentous structures on the physical examination. The plain radiographs obtained a wedge-shaped, like the meniscus, bony fragment at the lateral side of the knee joint (Fig. 1). MR imaging of this knee was performed to evaluate the ossific density. A well-defined lesion which was seen in the discoid lateral meniscus was isointense to the bone marrow on all pulse sequences, with a complete hypointense rim (Fig. 2aed). The lesion size was 36*30*6.5 mm. This was reported as a meniscal ossification. The articular cartilage was also normal. Mild synovial effusion was detected. In addition, a simple cyst of the proximal fibula was detected.

“…Meniscal ossicle was first reported in 1931 and later by Burrows [ 1 ] and by Watson-Jones and Roberts [ 2 ] in 1934. To the best of our knowledge, it has been reported 42 times so far [ 3 , 4 ]. Most of the reported cases were located in the posterior horn of the medial meniscus [ 5 , 6 ].…”

“…The literature is silent about the appropriate type of conservative management. Arthroscopy is a definitive modality, and arthroscopic removal of ossicles is usually the last resort [ 4 ]. MRI can definitely distinguish between the two, and diagnostic arthroscopy can be avoided.…”

“…Then checking titles and abstracts, 55 full texts were screened and 36 of these were included for data extraction. Furthermore, two articles were retrieved from reference lists, thus a total of 38 articles [1, 3–8, 10, 11, 14, 16, 19, 21–28, 30, 31, 34–36, 38, 41–45, 47, 49, 50, 54–57] were used for our systematic analysis. All were case series or reports; no interventional or observational studies were identified.…”

PurposeThe purpose of this study was to systematically review case reports and case series about meniscal ossicle, to summarize existing evidence. Specifically, to identify the etiology, demographic characteristics, localization, clinical features, diagnostic procedures and treatment options of this rare entity. Although, case reports/ series are of low level of evidence, a systematic review of such studies can provide and help us to gain a better understanding and awareness of meniscal ossicle. MethodsTwo authors searched three online databases (MEDLINE, SCOPUS and GOOGLE SCHOLAR) from inception until March 2020 for the literature on meniscal ossicle. Inclusion criteria included case series, case reports and case‐based reviews, available in full‐text version, in English and that concern humans. Reports published in languages other than English were excluded, as well as articles with no electronic full text availability. Case reports using the term “meniscal ossicle” to describe an acute avulsion fracture of the tibial root of the meniscus, were also excluded. ResultsOf 453 initial studies, 38 studies satisfied inclusion criteria. In total 169 patients were included of whom 107 (63%) were males and 62 (37%) were females. Mean age was 44 years (range 12–87). According to Magnetic resonance imaging findings, in 144 knees (86%) the ossicle was localized at the posterior root or horn of the medial meniscus. 60% of the patients had a history of trauma. The predominant symptom in 87% of patients was knee pain. In all patients was detected an intra‐articular density structure in computed radiography. 76% had associated meniscal tear, 61% had intraarticular cartilage loss, 34% meniscal extrusion and 28% anterior cruciate ligament injury. Treatment modalities included conservative regimen in 40 patients, while 59 patients underwent surgical excision. ConclusionThe most possible etiology of meniscal ossicle is posttraumatic heterotopic ossification and small occult bony avulsion fracture. It is commonly observed in individuals complaining about knee pain with history of antecedent trauma. The presence of a meniscal ossicle should alert the physician to the high likelihood of the patient having an associated meniscal tear, articular cartilage loss, ACL injury or meniscal extrusion. Along with the meniscal ossicle, the associated meniscal tear should be treated as well.
