Reliability of Modified Harris Hip Score as a tool for outcome evaluation of Total Hip Replacements in Indian...

Standard Harris Hip Score (HHS) is a validated tool, to measure the functional status of an individual and has been traditionally used to assess the condition of a patient with hip pathologies. Harris hip score in its standard form includes a physician's physical examination component which has a high inter-observer variability. A modified version of HHS (MHHS) was devised and brought into use, but has not been validated as an outcome measure, post total hip replacement (THR) in Indian population.

101 patients with 122 hips for whom THR was done, were followed up, and HHS and MHHS were recorded at a minimum followup of 6 months.

The mean MHHS was 78.97 with a standard deviation of 15.017. There was positive correlation between the two functional outcome scores with a p value of 0.001. MHHS was found to be reliable with a significant intraclass correlation coefficient (p = 0.001).

MHHS is a reliable and valid tool to measure functional outcome in patients undergoing Total Hip Replacements.
