  1. DISEASES OF THE MUSCULOSKELETAL SYSTEM PART 2

  2. Ligament Injury – Anterior Cruciate Ligament Rupture • ACL and PCL (posterior cruciate ligament) • stabilize knee joint • Intra-articular structures • Ruptured ACL – most common stifle injury and leads to DJD • May be complete rupture or partial tear => unstable joint => DJD

  3. TRAUMA: CRUCIATE LIGAMENT INJURY/RUPTURE

  4. TRAUMA: CLINICAL SIGNS OF CRANIAL CRUCIATE LIGAMENT INJURY/RUPTURE Middle-aged obese dog Highly active, athletic animals

  5. TRAUMA: CLINICAL SIGNS OF CRANIAL CRUCIATE LIGAMENT INJURY/RUPTURE Animal is acutely non wt. bearing on the rear leg after hyperextending the stifle joint Joint effusion

  6. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE Cranial drawer test Tibial compression test

  7. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE http://www.youtube.com/watch?v=9jg9E2nBt_E&feature=related

  8. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE REPAIR Extra-articular Stabilization *Most successful in patients less than 15kg

  9. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE REPAIR Intra-articular stabilization – Over-the-top patellar tendon graft

  10. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE http://www.youtube.com/watch?v=4nU2QZjjByg

  11. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE REPAIR Intra-articular stabilization technique TPLO – Tibial Plateau Leveling Osteotomy

  12. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE http://www.youtube.com/watch?v=-1pxxX4TXko&feature=fvw

  13. TRAUMA: CRANIAL CRUCIATE LIGAMENT RUPTURE – CLIENT INFO • Restrict activity 3-4 weeks post surgery • Cage rest • Leash walk only to urinate and defecate • Gradually increase exercise 4-8 wks post sx • Full activity 8-12 weeks • Opposite cruciate often tears within 1 yr • Weight loss helps • DJD of stifle joint likely • If no surgery, joint thickens - fibrosis
