Summary
A glomus tumor caused knee pain after total knee replacement (TKR). Surgical removal relieved pain and restored function, highlighting the need for thorough clinical assessment in TKR patients with persistent pain.
Area of Science:
- Orthopedic Surgery
- Oncology
- Pathology
Background:
- Persistent pain after total knee replacement (TKR) is a frequent complication, impacting patient satisfaction.
- Osteoarthritis is a common indication for TKR, but other pathologies can cause post-operative knee pain.
Observation:
- A glomus tumor was identified as the cause of anterolateral knee pain two years post-TKR.
- The patient experienced significant pain despite an otherwise successful TKR for osteoarthritis.
Findings:
- Excision biopsy under general anesthesia was performed for the glomus tumor.
- Histopathological examination confirmed the diagnosis of a glomus tumor.
- Tumor removal resulted in complete pain relief and functional recovery.
Implications:
- This case underscores the importance of comprehensive clinical evaluation for patients with persistent knee pain after TKR.
- Coincidental pathologies, such as glomus tumors, should be considered in the differential diagnosis.
- Prompt diagnosis and treatment of incidental findings can significantly improve patient outcomes and satisfaction following TKR.
