PURPOSE: Various modes of therapy have been directed at breaking the vicious cycle at early stage of synovitis in haemophilia patients. This study was planned to assess the short-term clinico-radiological outcome of chronic knee synovitis among haemophilia A patients post phosphorus-32 (P-32) radiosynoviorthesis.
METHODS: P-32 samarium radiocolloid was injected into the knee and patients were followed up at 1 and 3 months, respectively. Clinical outcomes was assessed using Tegner Lysholm scores (TLSs), Modified Knee Society Clinical Rating System (MKSS) score and circumference of the knee joint. The radiological outcomes were assessed using X-ray, ultrasonography and bone scan.
RESULTS: Among the fifteen haemophilia A patients studied, there was statistically significant difference in TLS ( χ2(2) = 27.887 and p value < 0.001), MKSS scores ( χ2(2) = 27.745 and p < 0.001) and circumference of the knee joint ( χ2(2) = 21.333 and p < 0.001) at preoperatively, 1- and 3-month follow-up. There were no changes noted in follow-up X-rays compared with the preoperative X-ray. Ultrasonography showed that clinical improvement was more in suprapatellar and medial parapatellar regions in the last 2 months compared to the first month of follow-up. Post P-32 bone scan showed marked decrease in uptake in the affected knee joint suggestive of radio ablation of synovial tissue.
CONCLUSION: P-32 radiosynoviorthesis done for chronic synovitis among haemophilia A patients showed significant improvement in both clinical and radiological parameters. Ultrasonography can be utilized as non-invasive radiological modality for follow-up of P32 response for knee joint.
