A 58-year-old woman suffered spontaneous recurrent hemarthrosis of the knee. In the clinical course, pigmented villonodular synovitis was mostly suspected, but in arthroscopic surgery the lateral meniscus appeared to be upturned and stuck into the lateral pouch with the meniscal ganglion cyst. It was suggested that meniscal tear with meniscal ganglion cyst was related with recurrent hemarthrosis. Generally, both the meniscal ganglion cysts and spontaneous recurrent hemarthrosis are highly rare conditions. In this case, we speculated that a negligible power could induce the meniscal tear with recurrent hemarthrosis in the particular situation in which the meniscal ganglion cyst existed. In other words, the meniscal ganglion cyst might basically and physically relate with hemorrhagic condition. Arthroscopically, the meniscal ganglion cyst was removed together with the anterior segment of the lateral meniscus. Recurrent hemarthrosis was treated successfully by resection of the meniscus.

Background: The association between size of ganglia or type of ganglia (intra-articular or extra-articular) and meniscal tears or severity of the osteoarthritis (OA) is not evaluated.
Purpose: To evaluate the prevalence, size, and location of intra- and extra-capsular ganglia at the gastrocnemius origin and to assess their associations with meniscal injury and grades of OA.
Material And Methods: This study included 301 consecutive patients who had knee pain and had undergone magnetic resonance imaging (MRI) of the knee.

Objective: To determine whether osteoarthritis (OA) pain characteristics and mechanistic pathways in pre-clinical models are phenotype-specific.
Design: Male 11-week-old C57BL6 mice had unilateral medial-meniscal-destabilization (DMM) or antigen-induced-arthritis (AIA), vs sham-surgery/immunised-controls (Sham/Im-CT). Pain behaviour (allodynia, mechanical- and thermal-hyperalgesia, hindlimb static weight-bearing, stride-length) and lumbar dorsal root ganglia (DRG) gene-expression were measured at baseline, day-3, week-1/-2/-4/-8/-16, and pain-behaviour:gene-expression:joint-pathology associations investigated.

Aim: To evaluate the prevalence, clinical relevance, and magnetic resonance imaging (MRI) features of extra-capsular ganglia at the gastrocnemius origin and to assess their association with internal derangement and osteoarthritis of the knee.
Materials And Methods: One hundred consecutive knee MRI examinations, obtained within a 6-month period from patients with no history of recent knee trauma, recent injections, inflammatory arthritis, infection, or tumours, were evaluated retrospectively for the presence of ganglia at the gastrocnemius origin. The lesions were divided into two groups: an intra-capsular and an extra-capsular group.
