recommended. If the hip is severely dysplastic,
a THR or FHO is advised.
Numerous techniques for open reduction
and stabilization of the hip have been described.
These can be extra‐articular or intra‐articular
repairs. The most common techniques are
reconstruction of the joint capsule with suture
and bone anchors, or the use of a synthetic
material to replace the ligament of the femoral
head, termed toggle rod stabilization (Figure
14.19). Both procedures provide immediate
stability to the hip. However, long‐term stability
is achieved from joint capsule healing and
periarticular fibrosis, as all synthetic materials
will eventually cycle and break.


Postoperative care and prognosis


Limb use following surgical repair is often
immediate. However, restricted activity is man­
datory for 8–12 weeks following surgery to allow
for the joint capsule and surrounding muscu­
lature to heal. Rehabilitation therapy, including
a home exercise program is strongly encour­
aged. Initially, static weight‐bearing exercises are


introduced along with short‐leash walks on even
terrain. Hill work and greater intensity strength
training is reserved until sufficient healing
occurs, usually about 6–8 weeks following
repair. The patient can return to full activity level
once range of motion of the hip joint and muscle
mass of the limb return to normal.
Repeat luxation is the most common compli­
cation. Until recently, this rate has been cited as
11–25% (Duff & Bennett, 1982; Bone et al., 1984;
Evers et al., 1997; Demko et al., 2006). Advances
in suture material have reduced the reluxation
rate following toggle rod stabilization to less
than 5% (Ash et al., 2012; Kieves et al., 2014).

Cranial cruciate ligament insufficiency


Anatomy

The CCL is composed of two bands, the smaller
craniomedial band that is taut in all phases of
flexion and extension of the stifle, and the cau­
dolateral band that is taut in extension, but lax
in flexion (Figure 14.20). Together, these bands
