Purpose
To evaluate the clinical and radiographic outcomes of patients with total elbow arthroplasty (TEA) and soft tissue reconstruction.
Methods
We investigated six patients who underwent TEA and soft tissue reconstruction (two elbows with 1-stage surgery and four elbows with 2-stage surgery). The mean patient age at the time of the surgical procedure was 43.2 years; the mean follow-up duration was 88.2 months.
Results
The mean pain visual analogue scale (VAS) during motion was improved from 6.3 pre-operatively to 0.7 at the last follow-up. The mean Mayo Elbow Performance Score (MEPS) improved from 26.7 pre-operatively to 81.7 at the last follow-up. The mean flexion-extension arcs of the 1- and 2-stage surgery groups increased from 12.5° and 13.8° pre-operatively to 72.5° and 100° at the last follow-up, respectively. The mean MEPS of the one and two stage surgery groups were 75 and 85, respectively, at the last follow-up. One of the six elbows had loosening on the simple radiograph at the last follow-up, and there were no cases with bushing wear. Three elbows needed additional skin debridement owing to wound complications (2/2 elbows in the 1-stage surgery group and 1/4 elbows in the 2-stage surgery group).
Conclusions
Under unfavorable soft tissue conditions, performing soft tissue reconstruction with TEA provides satisfactory functional improvement and pain relief. The two stage surgery provided a lower rate of wound complication and better elbow function than the one stage surgery, which led to high patient satisfaction post-operatively.
Level of evidence
Therapeutic Level IV.
