|October 1, 1979
Summary
Two new cases of multiple ossicles within human menisci highlight their occurrence in the posterior horns. These findings add to the known cases of these rare intra-articular bone formations.
Area of Science:
- Orthopedic Surgery
- Human Anatomy
Background:
- Meniscal ossicles are rare intra-articular bone formations within the knee joint.
- Previous literature documented 18 cases of meniscal ossicles.
Observation:
- Two novel cases of multiple ossicles within the posterior horns of semilunar cartilages are presented.
- Case 1 involved two ossicles in a 16-year-old female with a Y-shaped longitudinal tear of the meniscus.
- Case 2 involved seven ossicles in the posterior horn of the meniscus in a 39-year-old female.
Findings:
- Multiple ossicles can be incorporated within the posterior horns of human menisci.
- Complex meniscal tears may be associated with meniscal ossicles.
- Surgical removal of meniscal ossicles can be challenging.
Implications:
- These cases expand the understanding of meniscal ossicle prevalence and morphology.
- Further research is needed to elucidate the etiology and clinical significance of multiple meniscal ossicles.
- Awareness of meniscal ossicles is important for accurate diagnosis and treatment planning in knee injuries.
