Patients with isolated displace patella fractures who underwent either open reduction and internal fixation or partial patellectomy experienced similar final range of motion, functional scores and complication rates, according to study results.
Researchers had 52 patients with isolated displaced patella fractures who underwent operative treatment between January 2002 and December 2009 complete outcome questionnaires and participate in a physical examination. Overall, 26 patients underwent partial patellectomy (PP) and 26 underwent open reduction and internal fixation (ORIF). Outcomes were measured using the Knee Outcome Survey – Activities of Daily Living Scale, SF-36 Health Survey and SF Musculoskeletal Function Assessment Survey.
At final follow-up, 94% of patients achieved radiographic union. The PP group had a total degree of motion of 118.8° vs. 113.7° in the ORIF group. Mean Knee Outcome Survey – Activities of Daily Living Scale score was 64.1 for the ORIF group and 62.1 for the PP group, according to the researchers. Additionally, no significant differences were observed between the groups with regard to SF-36 mental component, Short Musculoskeletal Function Assessment Function Index or Short Musculoskeletal Function Assessment Bother Index.
According to the researchers, complication rates did not differ significantly between the two groups. – by Casey Tingle
