Relationship Between Intraosseous Pressures and Intra-Articular Pressure in Arthritis of the Knee: An Experimental Study in Immature Dogs

Abstract: The influence of chronic synovial inflammation and effusion on the juxta-articular bone haemodynamics in the juvenile knee was studied in 12 immature dogs with Carragheenin-induced unilateral arthritis. Using a fluid filled electromanometric pressure recording system simultaneous pressure measurements were taken from the distal femoral metaphysis, juxta-articular epiphyses and knee joint cavity in general anaesthesia followed by intraosseous phlebographies. During resting conditions the intraosseous pressure o… Show more

“…Passive intraosseous venous congestion of microvascular patellar blood flow could theoretically occur in the setting of increased intraarticular pressure as a result of an articular joint effusion (19,20). Our data, however, did not show a significant relationship between the presence of a joint effusion and visualization of increased T2-weighted subcortical signal intensity changes.…”

“…All MR examinations were performed with a 1.5-T MR unit (Signa; GE Medical Systems, Milwaukee, Wis) and dedicated quadrature extremity coils. 20.83-kHz bandwidth, 4.0-mm-thick sections with a 1.0-mm gap, 14-cm FOV, and 256 ϫ 192 matrix). In all patients, surgery was performed by one orthopedic surgeon (E.B.)…”

“…This results in an acute, and on repeated provocation, in a chronic nonspecific inflammation ( 19). Repeated intra-articular injections of carragheenan into the immature dog knee result in a chronic non-specific arthritis, being reproducible with respect to haemodynamic changes and growth disturbances (2)(3)(4) resembling those of human juvenile chronic arthritis and haemophilic arthropathy ( 1,7 ) . The leukotrienes ( 15), generated via 5-lipoxygenase (LO) pathway of arachidonic acid (AA), comprise the peptidoleukotrienes (LIT,, LTD, and LTE4), being mediators of immediate hypersensitivity, and leukotriene B4 (LTB,), which is one of the most chemotactic and chemokinetic agents known (9,18).…”

“…In the last three decades, several authors have described a direct correlation between IOP and regional blood perfusion [ 10,[17][18][19][20], In 1975, Wilkes and Visscher [21] demon strated that IOP recording is a reliable meth od for bone blood flow assessment. IOP is a measurement of the gradient between arterial and venous pressure and therefore reflects bone blood flow.…”

“…IOP was measured in the distal femoral epiphysis by transcuta neous bone cannulation according to Biinger et al (10,17], The insertion of the cannula into the epiphysis, distal to the growth plate, was performed under the guidance of an image intensifier. The tip of the cannula was placed in the middle of the lateral femoral condyle.…”
