Predictors for outcome in acute lateral epicondylitis

Area of Science:

• Orthopedics
• Sports Medicine
• Physical Therapy

Background:

• Lateral epicondylitis (tennis elbow) is a common condition with persistent symptoms.
• Predictors for treatment success and pain require identification for effective management.
• A randomized controlled trial investigated physiotherapy with or without corticosteroid injection for acute lateral epicondylitis.

Purpose of the Study:

• To identify predictors of treatment success in lateral epicondylitis.
• To determine factors associated with pain levels in lateral epicondylitis patients.
• To inform clinical decision-making for managing acute lateral epicondylitis.

Main Methods:

• Utilized data from a randomized controlled trial (NCT00826462).
• Assessed treatment success and VAS pain scores at 6, 12, 26, and 52 weeks.
• Employed univariate and multilevel logistic/linear regression analyses to identify prognostic indicators.

Main Results:

• High Pain Free Function Index scores consistently predicted reduced treatment success.
• Paid sick-leave and recurring complaints initially improved but later decreased success.
• Baseline overall complaint scores were the strongest predictor of increased pain.

Conclusions:

• Baseline pain, overall complaint severity (VAS), and functional index scores help identify patients with potentially protracted lateral epicondylitis.
• These factors aid in stratifying patients for more serious or prolonged conditions.
• Informed patient assessment can lead to more targeted and effective treatment strategies.
