Stifle: lateral - parapatellar approach
Synonym(s): Lateral parapatellar stifle arthrotomy
Contributor(s): Toby J Gemmill
Introduction
- To access the stifle joint.
Uses
Advantages
- Most stifle procedures can be performed via the lateral parapatellar approach.
- Very safe because major neurovascular structures are caudal to stifle.
- A more limited lateral subpatellar arthrotomy can be used if desired, to allow access to the femorotibial joint but minimize morbidity. With this approach the incision is made 2-3 mm lateral to the straight patellar tendon, but only runs from the distal pole of the patellar to the tibial crest. The incision is not continued proximally alongside the patella.
Disadvantages
- Access to the caudal joint is limited
- The peroneal nerve (coursing just caudal to the fibular head) and the popliteal artery (lying deep to the lateral fabella) can be damaged during procedures involving placing sutures and/or the passage of a graft passer in that region.
