This meta-analysis examined the impact of prior arthroscopic surgery on postoperative infection risk following knee, hip, and shoulder arthroplasty, analyzing 31 observational studies. It found that previous arthroscopic surgery significantly increased the risk of overall infection (OR = 1.33) and deep infection (OR = 1.38), particularly for knee and shoulder arthroscopies, while hip arthroscopy showed no significant correlation with infection risk.
Key findings
- Prior arthroscopic surgery increased overall infection risk after arthroplasty (OR = 1.33).
- Deep infection risk was significantly elevated with prior arthroscopic surgery (OR = 1.38).
- Knee arthroscopy was linked to higher postoperative infection risks.
- Shoulder arthroscopy notably increased the risk of deep infection.
Why it matters
Understanding the joint-specific risks associated with previous arthroscopic surgeries can help clinicians better assess infection risks when planning arthroplasty procedures, ultimately improving patient outcomes.
