The quality of life analysis of knee prosthesis with complete microprocessor control in trans-femoral amputees

Abstract

Objective: The aim of this study was to analyze the patient demographics, etiology of limb loss as well asreporting SF-36 scores for microprocessor prosthesis users in Turkish population.Methods: We reviewed 72 patients (61 male and 11 female; mean age: 37.7± 10.7) with uni-lateral,above knee amputation and a history of regular and microprocessor prosthesis use. All patients werecalled back for a last follow-up and they were asked toŞll a self-administered general health statusquestionnaire (SF-36).Results: According to the SF-36 results; physical component score (PCS) score was 46± 7.3 and mentalcomponents summary (MCS) score was 46.5± 9.1. These scores have statistical similarity with Turkishhealthy controls, except SF (social functioning) sub-dimension. PCS score for women microprocessorusers were signiŞcantly lower than men (43.3 vs. 48.7, p ¼ 0.03), but MCS scores were similar in betweengenders (46 vs. 48.2, p¼ 0.13). Conventional prostheses usage time was positively correlated withphysical function (PF) scores (r¼ 0.322, p ¼ 0.010). Microprocessor prosthesis usage time was negativelycorrelated with role limitations due to emotional problem (RE) scores (r¼ 0,313, p ¼ 0.009).Conclusion: The quality of life surveys were showed that the loss of an extremity have higher physicaland psychological impact on women's physical scores. Overall, SF-36 results were similar in microprocessor using amputee's and Turkish normal controls.Level of evidence: Level IV, therapeutic study.
