Abstract
There is a paucity of published literature regarding the long-term outcomes of the modern generations of total joint arthroplasty (TJA) of the first metatarsophalangeal joint. Between 1999 and 2001, we recruited 63 patients into a randomised controlled trial of arthrodesis vs TJA. The 2 year results were published in 2005.
At a mean follow-up 15.2 years (range 13.2–17.2), all patients from the original trial were contacted. Data were collected in the form of visual analogue score for pain (VAS), visual-Analogue-Scale Foot and Ankle (VAS FA) as well as information on any revision procedures.
Data were available from all surviving patients (66 toes 53 patients). There was no difference in pain scores between the arthrodesis group and arthroplasty group 7.4 ± 15.7 vs 15.7 ± 19.7 (p=0.06). There was also no difference in the VAS FA scores as a whole 88.9 ± 12.9 vs 86.1 ± 17.1 (p = 0.47), or when divided into its 3 components (pain, function and other complaints). There was however a significant difference with regards to patient satisfaction with the arthrodesis group outperforming the TJA group: 95.5 ± 10.4 vs 83.6 ± 20.9 (p<0.01). There was a significantly higher rate of revision surgery in the TJA group when compared to the arthrodesis group (p= 0.009).
At 15 years the patients that underwent arthrodesis were more satisfied and had a greater survivorship compared to TJA, however there was no difference in outcome with regards to pain or function between the two groups. Based on the results of this study arthrodesis remains the ‘gold standard’ due to excellent pain relief, high function and low risk of revision surgery.
