This is a report on a aseptic synovitis diagnosed and treated arthroscopically following the meniscal repair using biodegradable Meniscus Arrow$^{(R)}$(Bionix Inc, Malvern, USA). Histological examination revealed chronic nonspecific synovitis and birefringent material. Immunohistochemical tests were positive in lysozyme, ${\alpha}$-1-antitrypsin and ${\alpha}$-1-antichymotrypsin. The patient was received arthroscopic synovectomy, and then pain and swelling of the knee joint was relieved. Range of motion was improved to full range. As far as we know, this is the first case of aseptic synovitis after meniscal repair using biodegradable Meniscus Arrow$^{(R)}$.

Purpose: The purpose of this study was to suggest a multimodal diagnostic approach to determine the cause of the disease in patients diagnosed with synovitis of the wrist and who underwent synovectomy. Materials and Methods: Twenty-nine patients, who underwent contrast magnetic resonance imaging (MRI) preoperatively and synovectomy from January 2000 to December 2013, were reviewed retrospectively. Among them, 17 patients underwent a $Tc^{99m}$ white blood cell (WBC) scan preoperatively. In patients who met the diagnostic criteria of rheumatoid arthritis (RA), the diagnosis was confirmed as RA if the MRI finding or histology was compatible with RA. If the MRI finding and histology were disparate, the final diagnosis was made based on the histologic finding. Results: Of the nine patients who met the diagnostic criteria of RA, seven patients were finally diagnosed as RA and two patients as tuberculous arthritis. Of the 20 patients who did not meet the diagnostic criteria of RA, the MRI findings and histology were consistent with the same disease in 12 patients. In the remaining eight patients, five were diagnosed with nonspecific chronic synovitis, one with RA, and two with tuberculous arthritis based on the clinical findings, MRI, and histology findings. Conclusion: MRI and a WBC scan are very useful imaging modalities for diagnosing the causative condition of the wrist synovitis. A histology evaluation after synovectomy can also be useful in cases with a difficult diagnosis or are refractory to medications.
