Case:
A 17-year-old boy had persistent knee pain 1 year after medial meniscal root repair augmented with bone marrow aspirate concentrate injection. Radiographs and magnetic resonance imaging (MRI) demonstrated an intrameniscal ossicle which was not present on MRI performed before 6 months. He underwent arthroscopic excision of the meniscal ossicle. At the 7-month follow-up, he had complete relief of his pain.
Conclusions:
It is possible that the meniscal ossicle developed because of osteoinductive cells and cytokines from the injected bone marrow or the drill hole for root repair and should be considered as a possible complication of this procedure.
Insights
A rare complication of knee surgery, intrameniscal ossicle, can cause persistent pain after meniscal root repair. Surgical removal of the ossicle provided complete pain relief in a teenage patient.
Area of Science:
- Orthopedic Surgery
- Regenerative Medicine
- Sports Medicine
Background:
- Persistent knee pain can occur after medial meniscal root repair augmented with bone marrow aspirate concentrate (BMAC).
- Intrameniscal ossicle formation is a potential, though uncommon, complication following such procedures.
Observation:
- A 17-year-old male experienced chronic knee pain one year post-medial meniscal root repair with BMAC.
- Imaging revealed an intrameniscal ossicle, an abnormal bone formation within the meniscus, which was absent in earlier scans.
Findings:
- The patient underwent arthroscopic excision of the intrameniscal ossicle.
- Complete pain resolution was achieved at the 7-month follow-up after the ossicle removal.
Implications:
- Intrameniscal ossicle should be considered a potential complication of meniscus repair augmented with BMAC or bone drilling.
- This case highlights the importance of recognizing and surgically addressing intrameniscal ossicles for successful pain management in young athletes.
