<h2>Patella Luxation – “Dislocating kneecap”</h2>
<p>The patella (knee cap) doesn’t sit in the centre of the groove on the lower femur. This is because three structures are not in a straight line:</p>
<ol>
<li>Bone at the front of the tibia</li>
<li>The groove in the lower femur</li>
<li>The muscles and tendons pulling on the patella</li>
</ol>
<p>When the patella is out of the groove, the groove becomes shallower, or the ridge may be worn away, making the problem worse.<br /><br />Causes include genetic factors, trauma or ligament problems but often cannot be tracked down precisely in any one dog. May dogs may have a combination of several causes.<br /><br />The patella rubs on the edge of the ridge or the rough bone to the side of the ridge. This wears away the cartilage, eventually causing pain and arthritis.</p>
<h6>Treatment:</h6>
<ol>
<li>Realign bone at front of tibia to match the muscle and femur (“tibial tuberosity transposition”). </li>
<li>Deepen groove of femur (“sulcoplasty”)</li>
<li>Loosen soft tissue on tight side (“release”)</li>
<li>Tighten soft tissue on loose side (“imbrication”)</li>
</ol>
<p><br />If ligament damage is also present, different or additional surgical treatments may be required (see Rupture of the Cranial Cruciate Ligament - Tibial Tuberosity Transposition Advancement).</p>

Just to say thank you. Cassie the Boxer is back running at top speed after her elbow operation. It's great to see her running around again. Thank you so much!...
