Lower extremity amputees are subject to increased physical demands proportional to their level of amputation. Lower extremity amputees have a 6-fold higher risk of developing radiographic osteoarthritis in the ipsilateral hip and a 2-fold risk of developing radiographic osteoarthritis in contralateral hip when compared with the non-amputee population. Additionally, there is a 3-fold increased risk of developing radiographic osteoarthritis in the ipsilateral hip after an above knee amputation when compared with a below knee amputation. The authors retrospectively reviewed 35 total hip arthroplasties after lower extremity amputation. The mean clinical follow-up was 5.3\u00b14.0 years. The mean time from lower extremity amputation to total hip arthroplasty was 12.2\u00b112.8 years after a contralateral amputation and 5.4\u00b16.0 years after an ipsilateral amputation (\n            <jats:italic>P<\/jats:italic>\n            =.050). The mean time to total hip arthroplasty was 15.6\u00b115.4 years after an above knee amputation and 6.4\u00b16.1 years after a below knee amputation (\n            <jats:italic>P<\/jats:italic>\n            =.021). There was a statistically significant improvement in the mean Harris Hip Score from 35.9\u00b121.8 to 76.8\u00b112.8 with total hip arthroplasty after a contralateral amputation (\n            <jats:italic>P<\/jats:italic>\n            &lt;.001). There also was a statistically significant improvement in the mean Harris Hip Score from 25.4\u00b121.7 to 78.6\u00b117.1 with total hip arthroplasty after an ispilateral amputation (\n            <jats:italic>P<\/jats:italic>\n            &lt;.001). Three (17.7%) total hip arthroplasties after a contralateral amputation and 2 (11.1%) total hip arthroplasties after an ipsilateral amputation required revision total hip arthroplasty. Patients with an ipsilateral amputation or a below knee amputation progress to total hip arthroplasty faster than those with a contralateral amputation or an above knee amputation, respectively. Lower extremity amputees experience clinically significant improvements with total hip arthroplasty after lower extremity amputation.
