This randomized study with a minimum 2-year follow-up showed patients who received platelet-rich plasma injection at the end of arthroscopic hip surgery for femoroacetabular impingement had less pain at 48 hours postoperatively and fewer joint effusions at 6 months compared with those who did not receive augmented treatment.
Researchers prospectively evaluated 57 patients (mean age 35.3 years) who underwent arthroscopic hip surgery for femoroacetabular impingement from May 2009 to January 2010. Of these patients, 30 were randomized to receive a platelet-rich plasma (PRP) injection after surgery and 27 patients did not receive this treatment. At 3 months, 6 months and 24 months, investigators clinically evaluated patients with the modified Harris Hip Score (mHHS). In addition, the VAS was used to evaluate pain at 24 hours, 48 hours, 3 months and 6 months postoperatively.
Findings showed no significant differences between the groups at both 24-month and 6-month follow-ups regarding mean mHHS. VAS scores at 48 hours after surgery for the PRP and control groups were 3.04 and 5.28, respectively. MRI evaluation showed the labral integration rate was not significantly different between the groups. MRI results also showed no evidence of effusion in 36.7% of patients in the RPR group compared with 21.1% of patients in the control group.‒ by Monica Jaramillo
