Three-Part Question:
IN [adults with arthritis of the big toe]
IS [arthroplasty better than arthodesis]
FOR [improvement in pain and function]
Clinical Scenario:
A 59 year old women has painful osteoarthritis of the 1st MTPJ (great toe). She has been told that a MTPJ fusion is the best surgical solution but has read on t'internet that there are now joint replacements for the big toe MTPJ. She asks for your advice but before imparting wisdom, you wonder if there has been any study comparing the two techniques.
Search Strategy:
Medline via OVID; EMBASE via OVID; the Cochrane collaboration from 1950 to June 2020

Outcome:
277 papers were retrieved. Three systematic reviews were identified which were relevant to the 3 part question. There were 2 RCTs found which were cited in some but not all these reviews. A 5 year follow up study of the 2015 RCT by Baumhauser et al was not included as there was a lack of outcome data for the group having arthrodesis.
Each systematic review contained different numbers of papers which were either prospective or retrospective case series of arthrodesis or arthroplasty. None of these were able to directly compare arthroplasty with arthrodesis for first MTPJ arthritis.

Author Commentary:
The 3 systematic reviews incorporate a mixture of RCT, and cohort and case studies comparing first MTPJ arthrodesis with arthroplasty. There are only 2 randomised trials comparing arthroplasty surgery versus arthrodesis (Gibson & Thomson 2005; Baumhauer et al 2016).
Bottom Line:
There is some evidence based mainly on retrospective non-randomised case series systematic reviews and 2 RCTs that arthrodesis is superior to arthroplasty at improving pain in symptomatic end stage hallux rigidus.
