To compare self-reported joint status, quality of life, level of activity and pain management in patients scheduled for surgical treatment of seven common ankle disorders: osteoarthritis (OA), primary osteochondral lesion of talus (P-OLT), recurrent osteochondral lesion of talus (R-OLT), lateral ankle instability (INST) and anterior (ANT-IMP), posterior (POST-IMP) and combined (COMB-IMP) ankle impingements.
The cross-sectional study design was implemented. Hospital records of 610 patients that were admitted for surgical intervention on the ankle joint over a seven year period were reviewed. Patient selection (over 18 years, no systemic musculoskeletal illnesses, only one isolated ankle pathology) resulted in 123 eligible patients for current study (OA 22, P-OLT 19, R-OLT 18, INST 15, ANT-IMP 20, POST-IMP 13, COMB-IMP 16). Foot and Ankle Outcome Score (FAOS), European quality of life in a visual analogue and in five dimensions (EQ-VAS, EQ-5D-3L), Tegner activity scale (TAS) and pain medication usage were recorded at the admission and compared across these seven groups.
All evaluated ankle disorders induced the following: (a) subjective joint-specific dysfunction - FAOS cumulative: 42 (OA), 50 (R-OLT), 65 (P-OLT), 65 (INST), 63 (ANT-IMP), 61 (POST-IMP), 60 (COMB-IMP); (b) decreased quality of life - EQ-5D-3L: 0.41 (OA), 0.44 (R-OLT), 0.56 (P-OLT), 0.62 (INST), 0.64 (ANT-IMP), 0.56 (POST-IMP), 0.60 (COMB-IMP) and (c) decreased activity level - TAS: 2.1 (OA), 2.7 (R-OLT), 3.7 (P-OLT), 4.0 (INST), 4.7 (ANT-IMP), 4.4 (POST-IMP), 5.1 (COMB-IMP). FAOS subscales, EQ-5D-3L and TAS were significantly lower in OA and R-OLT patients. Between 31% (POST-IMP) and 68% (OA and R-OLT) of patients required pain medication over one month prior to the assessment.
All analysed ankle disorders in patients amenable for surgical treatment induced a considerable decline in patients` perceived ankle function, quality of life and activity level. The worst subjective ankle status was reported equally by OA and R-OLT patients, while patients with the other five disorders reported comparable values.
