Event Description
This unsolicited case from united states was received on (b)(6) 2018 from a patient. This case involves a (b)(6) female patient who received treatment with synvisc one and on the same day could not put weight on either knee, couldn't walk, knee swelling, knee pain. Also, device malfunction was identified for the reported lot number. No relevant past drugs were reported. Relevant medical history included surgery in 2005. Relevant concurrent conditions included sjogren's for which patient was being treated with hydroxychloroquine sulfate (plaquenil). The patient stated that she has no history of allergy to chicken, feathers, eggs, or other bird protein on (b)(6) 2017, the patient received an injection of the recalled lot of synivsc-one, once (route: intraarticular; lot/batch number: 7rsl021; indication: not provided) in each knee. The patient stated that she had never received synvisc or synvisc-one before, prior to (b)(6) 2017. That same evening, the patient began to experience a lot of swelling and a lot of pain in both knees, she could not put weight on either knee, and she could not walk, and these symptoms persisted for several days before improving; then, on (b)(6) 2017, the pain, swelling, unable to bear weight on her knees, and inability to walk, started all over again. The patient stated that she had experienced pain and swelling in both knees off and on ever since then. On a scale of 0 to 10, with 0 being no pain and 10 being the most severe pain, the patient estimated her knee pain at its worst, after the synivsc-one injections, as a 9. The patient stated that the pain was severe enough that she was tempted to go to the emergency room, but she did not, and she stated she had not been hospitalized for her adverse knee symptoms. The patient stated that she called her doctor's office, and they asked if she had any pain medication around the house, which she did, so she treated her pain with some hydrocodone bitartrate/paracetamol (hydrocodone w/acetaminophen) 5/500 that she had left over from surgery in 2005, and the patient stated it was expired. The patient was currently treating her knee symptoms with some acetaminophen daily, ice, and elevation. The patient stated that she could not take naproxen because it increases her blood pressure. The patient stated that she engaged in no strenuous physical activities such as tennis or jogging after the synvisc-one injections. The patient stated that she had experienced no fever, and had no blood work done in relation to the synvisc-one injections. On an unknown date in (b)(6) 2018 (last week), the patient had some fluid drawn from both knees and sent for testing, and the test results came back ok. The patient stated she did not have any prosthetics. The patient stated she had not received immunosuppressants. The patient stated that her only chronic condition was sjogren's. The patient received the synvisc-one injections from supply on hand at the doctor's office, so she did not have information on storage. The patient stated that she might have had some numbing agent injected into her knees at the same time as synvisc-one. Corrective treatment: hydrocodone bitartrate/paracetamol (hydrocodone w/acetaminophen), ice, and elevation for device malfunction, could not put weight on either knee, couldn't walk, knee swelling, knee pain outcome: not recovered/not resolved for all the events seriousness criteria: important medical event for device malfunction a product technical complaint was initiated with the following results: an investigation was initiated as a result of an unexpected increase in the number of labelled adverse events received from the us market for synvisc one, lot 7rsl021.
