CASE 557.—Private W. Patterson, Co. K, 6th Wisconsin, aged 36 years, was wounded through both knees, at Gainesville, August 28, 1862. He was treated at Carver Hospital, Washington, whence he was discharged and pensioned December 9, 1862, Surgeon O. A. Judson, U. S. V., certifying to: "Shot wound of both knee joints, involving a fracture of the right patella and causing extensive effusion in the left knee joint." Examiner J. Hobbins, February 18, 1863, certified to "imperfect flexion and limited and difficult extension," resulting from the wounds. Examiner D. C. Green, of Mauston, Wisconsin, reported, April 28, 1870: "The wound was caused by a ball which entered the left knee at the left side and passed through, striking the bone. The missile then, being slightly turned in its course, struck the right knee and passed through it anteriorly, fracturing the patella and lacerating the muscles badly. At present both knee joints are stiff." Subsequent examiners report no additional information. The pensioner was paid December 4, 1879.
