Abstract
PICO question
 In cats with traumatic coxofemoral injury, does total hip replacement (THR) offer improved outcome when compared with femoral head and neck excision (FHNE) arthroplasty?
 
 Clinical bottom line
 Category of research question
 Treatment
 The number and type of study designs reviewed
 One paper was critically reviewed. It was a non-randomised retrospective observational study
 Strength of evidence
 Moderate evidence
 Outcomes reported
 THR results in superior clinical outcome and owner satisfaction compared to FHNE in cats
 Conclusion
 In cats with traumatic coxofemoral injury, although the evidence is not conclusive and somewhat limited, the literature reviewed here suggests that THR offers a superior outcome in feline patients.
 There is currently insufficient evidence to determine if there is a difference in long-term outcome, complications or osteoarthritis (OA) development following THR or FHNE in feline patients
 
 How to apply this evidence in practice
 The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
 Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care.
 
Highlights
Superior return to normal thigh circumference following THR compared to FHNE (98% compared with 92%)
Mild reduction in hip flexion with THR 29° ± 10° (98%) compared with mild increase in hip flexion with FHNE 32° ± 3° (103%) Improvement in pain-free range of hip joint motion in THR compared with FHNE
This paper looked at owner satisfaction as an outcome for each procedure and found a reported improvement in the THR group compared to the FHNE group
