Figure 3. Synovial pressure (Pj)-flow (Qs) relations in rabbit knee joints treated with intra-articular leech hyaluronidase in Ringer solution (left knee, filled symbols) or plain Ringer solution (right knee of same animal, open symbols).
The dashed regression lines were fitted above and below yield pressures. The latter were identified by inspection. Slopes are given in the text. Squares show results below yield pressure and circles show results above yield pressure.
