5 days later patient experienced left knee pain that has increased, pain with walking, tenderness at medial joint line, tenderness at lateral joint line, pain worsened by standing and walking, lower extremity pain, severe, swelling present, weak flexion, "weqak" extension and limping gait; 6 days later had a/g ratio low , hdl cholesterol high , ldl high , vitamin b12 high, rdw low, mch high, rbc low, wbc low; after unknown latency developed, creatinine high 0.92 mg/dl, glomerular filt.Rate low 58 ml/min/1.73m2, inr low 0.94 na, partial thromboplastin time decreased 21.9 seconds.A device malfunction was noted in the reported lot number.No relevant past drugs, concomitant medications and concurrent condition were reported.Patient had history of back; cholecystectomy; colonoscopy; endoscopy; gallbladder; hysterectomy; lumbar laminectomy surgery and osteoarthritis (joint line tenderness and crepitus), arthritis; arthritis: knee; gastroparesis; hyperlipemia; hypertension; limb swelling; liver disease; lower back pain; lumbago/low back pain; lumbar disc herniation, l2-3; lumbar spinal stenosis; pain: bilateral knee; pre-op examination; rotator cuff tendinitis, right; spondylolisthesis, lumbar.Concomitant medications included altace; aspirin; atenolol; benadryl; biotin; calcium; domperidone; dyazide; fibercon; melatonin; "ramiprii"; sam-e; triamterene-"hydrochlorothiazid" 37.5-25 mg oral tablet; vitamin b-12; vitamin b-6.On (b)(6) 2017, the patient received treatment with intra-articular synvisc one injection, at an unknown dose for left knee pain and primary osteoarthritis of left knee (lot number: 7rsl021).On an unknown date, after unknown latency, patient developed creatinine high 0.92 mg/dl, glomerular filt.Rate low 58 ml/min/1.73m2, inr low 0.94 na, partial thromboplastin time decreased 21.9 seconds.On (b)(6) 2017, a day after initiating treatment, patient was noticed to have left knee series demonstrating moderate to marked degenerative change with "chondrocaicinosis".On (b)(6) 2017, 5 days after initiating, patient developed experienced left knee pain that has increased, pain with walking, tenderness at medial joint line, tenderness at lateral joint line, pain worsened by standing and walking, lower extremity pain, severe, swelling present, weak flexion, "weqak" extension and limping gait.On (b)(6) 2017, 6 days after initiating treatment, patient developed a/g ratio low , hdl cholesterol high , ldl high , vitamin b12 high, rdw low, mch high, rbc low, wbc low.On (b)(6) 2017, patient recovered from weak flexion, "weqak" extension.Corrective treatment: walker, ice, hydrocodone bitartrate/paracetamol (norco), ketorolac tromethamine (toradol) for left knee pain that has increased, pain with walking, tenderness at medial joint line, tenderness at lateral joint line, pain worsened by standing and walking, lower extremity pain, severe; not reported for rest of the events.A product technical complaint was initiated on 16-may-2018 for synvisc one, batch number: 7rsl021, global ptc number (b)(4).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.The product met all release testing at time of manufacture in june 2017.Retain samples were retested due to the unexpected increase in adverse events.Higher than expected endotoxin results were obtained.In addition, the presence of microbial contamination was also confirmed.The cause of these events is under investigation.Once this investigation is completed, corrective and preventive actions will be implemented.Outcome: recovered for weak flexion, "weqak" extension; unknown for rest of the events.Seriousness criteria: disability for left knee pain that has increased, pain with walking, tenderness at medial joint line, tenderness at lateral joint line, pain worsened by standing and walking, lower extremity pain, severe, device malfunction.Follow up as received on 16-may-2018.Global ptc number was added.Text amended accordingly.
