Patients with lower-extremity amputations who underwent total hip arthroplasty experienced clinically significant improvements, according to results of a study published recently in Orthopedics.
Researchers reviewed 35 total hip arthroplasties (THAs) among patients with a lower-extremity amputation and a minimum of 2-years follow-up.
After a contralateral amputation, results showed the mean time from lower-extremity amputation to THA was approximately 12.2 years compared with approximately 5.4 years for after an ipsilateral amputation. The researchers also found the mean time to THA was 15.6 years following an above-knee amputation, compared with 6.4 years following a below-knee amputation.

THA after both a contralateral and ipsilateral amputation resulted in a statistically significant improvement in the mean Harris Hip Score, from 25.4 to 78.6, according to study results. The researchers also found 17.7% of THAs after a contralateral amputation and 11.1% of THAs after an ipsilateral amputation required revision THA.
According to the researchers, patients who underwent ipsilateral amputation or a below-knee amputation progressed more quickly to THA compared with patients who underwent contralateral or above-knee amputation. – by Casey Tingle
