RESUMO
Deep flexion activities including kneeling are desired by patients after total knee arthroplasty. This in vivo radiographic study sought to reveal the effect of tibial insert design on tibiofemoral kinematics during kneeling. One group of patients received standard posterior stabilized tibial inserts, whereas the other group received posterior stabilized tibial inserts (Flex inserts) that were designed to allow more flexion. The patients with the Flex inserts achieved greater range of motion without different tibiofemoral contact behavior.

We report a case of appendiceal colic presenting as chronic right lower quadrant abdominal pain, without leukocytosis or other inflammatory signs, following an uneventful colonoscopic exam without biopsy or polypectomy. The resected appendix appeared grossly abnormal and was engorged with fecal material. The patient was immediately relieved of pain and remains so four years postoperatively. We conclude that insufflation of the cecum caused inspissation of fecal material into the lumen of the appendix. The ensuing incomplete or partial obstruction of the appendiceal lumen resulted in development of appendiceal colic without any signs or symptoms of inflammation.
