60 y.o. Male s/p Revision TKR with Pain and Instability

By Elliot Gross

60 yo male 1 yr post revision TKR with PS knee with well fixed long stems has chronic pain and effusions. Infection workup neg, also has 3+ AP laxity at 90 degrees and moderate med-lat laxity in any midrange. ROM 4 hyper to 115 flex. Very stable at full extension. Will a more constrained and a slightly thicker poly insert solve problem?
