Background:
Lateral epicondylitis (LE)1 affects between 1 and 3% of the population. Recently, platelet-rich plasma (PRP)2 has gained popularity.
Aim:
Assess the long-term outcomes of PRP for patients with refractory LE.
Methods:
We assessed 31 patients who had failed conservative management using the Oxford Elbow Score (OES).3.
Results:
Mean follow-up: 5.2 years (range 4.2-6.1 years).87.1% exhibited minimum clinically important difference (MCID)4 in pain scores between pre-op and long-term. 90.3% displayed MCID in function and psycho-social domains.Two patients had a repeat injection and six underwent open release.
Discussion:
PRP is successful in treating refractory LE in most patients and avoiding surgery.
