Abstract:
We report the case of a 44-year-old man who underwent a partial medial meniscectomy for a meniscal tear whose postoperative course was complicated by the development of heterotopic ossification (HO) within the medial arthroscopic portal. Following a routine initial procedure, the patient presented with ongoing pain and a palpable, painful lump around the previous medial arthroscopy portal. Plain radiographs and MRI were suggestive of a bony structure within the soft tissues. Histopathological examination at repeat arthroscopy confirmed osseous tissue consistent with HO. Recovery after the second procedure was rapid and resulted in normal knee function and complete pain relief. HO within an arthroscopy portal is a rare complication following arthroscopic partial meniscectomy in the knee and has not previously been described in the literature.
Insights
Heterotopic ossification (HO) is a rare complication following knee arthroscopy. This case study details a patient who developed HO within an arthroscopic portal after a partial meniscectomy, successfully treated with repeat arthroscopy.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Regenerative Medicine
Background:
- Arthroscopic partial meniscectomy is a common procedure for treating meniscal tears.
- Postoperative complications, though infrequent, require careful monitoring and management.
- Heterotopic ossification (HO) involves abnormal bone formation in soft tissues.
Observation:
- A 44-year-old male developed persistent pain and a palpable mass at the medial arthroscopic portal site after a partial medial meniscectomy.
- Imaging studies including plain radiographs and MRI indicated a bony structure within the soft tissues.
- Histopathological examination confirmed the presence of osseous tissue, consistent with HO.
Findings:
- The patient's symptoms were attributed to heterotopic ossification within the medial arthroscopic portal.
- Repeat arthroscopy was performed to address the complication.
- Histopathology confirmed the diagnosis of HO.
Implications:
- This case highlights a previously undescribed complication of arthroscopic partial meniscectomy.
- Awareness of HO within arthroscopic portals is crucial for accurate diagnosis and management.
- Prompt surgical intervention led to excellent patient outcomes, including pain relief and restored knee function.
