Summary
Fast-track unicompartmental knee arthroplasty (UKA) shows potential for quicker recovery, but current utilization suggests underuse. High-volume centers achieve more same-day discharges, indicating room for improvement in patient recovery protocols.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Fast-track Protocols
Background:
- Unicompartmental knee arthroplasty (UKA) is an alternative to total knee replacement.
- Fast-track protocols aim to optimize patient recovery and reduce hospital stay.
- Variations in UKA utilization and outcomes exist across different surgical centers.
Purpose of the Study:
- To analyze trends in length of stay and early complications after UKA.
- To compare length of stay between high and low utilization UKA centers.
- To evaluate the effectiveness of fast-track protocols in UKA.
Main Methods:
- Prospective multicenter study of 3,927 UKA procedures (2010-2018).
- Data collected on length of stay, 30- and 90-day readmissions, and mortality.
- Centers categorized by UKA utilization (percentage and annual volume).
Main Results:
- Mean length of stay was 1.1 days, with no significant change over time.
- Same-day discharge rates varied widely (0-50%), higher in high-utilization centers.
- 90-day readmission rate was 6.9%; 90-day mortality was 0.08%.
Conclusions:
- UKA in a fast-track setting has underutilized potential for rapid patient recovery.
- High-utilization centers demonstrate better same-day discharge rates.
- Further optimization of fast-track protocols could enhance UKA outcomes.
