Abstract
Introduction Ankle fusion is still considered as an established therapy for end-stage ankle osteoarthritis.
To determine exact description of postoperative functioning, it is necessary to consult
a variety of functional scores and quality of life questionnaires.
Methods/Patients 34 patients with 34 ankle fusions were investigated on average 5.9 years postoperatively
by functional tests and health-related quality of life questionnaires (AOFAS hindfoot
score [AOFAS: American Orthopaedic Foot/Ankle Society], Foot Function Index [FFI],
Lower Extremity Functional Scale [LEFS], Lower Extremity Activity Scale [LEAS], Visual
Analogue Scale Foot/Ankle Surgery [VAS FA], Short Form 36 [SF-36], EuroQol 5D [EQ-5D]).
Results After ankle fusion: the majority of cases gain pain reduction, but residual symptoms
may persist; the maximum walking distance (subjectively more than objectively) will
be extended; rarely walking without any aids can be achieved; in most cases, the gait
pattern is only slightly changed; the re-entry into working life is often possible;
climbing stairs without any restrictions is not always possible; the psychological
situation will be equalized with that of healthy people.
Conclusion The results of the study confirm the success rates of ankle fusions in the majority
of cases. Well defined limitations and residual symptoms can be named on the basis
of the available data.
