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.
