Introduction: Total Hip Arthroplasty (THA) has become a standard procedure in treating hip coxarthrosis and the treatment of femoral head necrosis and femoral neck fracture. THA effectively reduces pain but has some functional limitations after the patient undergoes the procedure. This study aims to evaluate the effect of intraoperative administration of platelet-rich plasma to the hip capsule and the correlation of the amount of mechanoreceptor in the hip capsule to the Harris Hip Score (HHS) and Berg Balance Test (BBT) 1 month after the procedure of total hip arthroplasty.
Methods: This study is a post-test-only randomized clinical trial. The patient who had to fulfill the inclusion criteria will be assessed using HHS and BBT for the functional outcome 1 month after the total hip arthroplasty procedure. The data was then analyzed using the Pearson test in SPSS version 25 for Windows.
Results: Based on the Independent-T Test result, we found that administration of PRP gave a significant result statistically to increase Harris Hip Score and Berg Balance Test 1 month after undergoing total hip arthroplasty (P<0,05). Based on the Pearson test, we found that there was a strong significant correlation between the amount of mechanoreceptor (free nerve ending) to HHS (r=0.756; p=0.002) and BBT (r=0.660; p=0.010) in the patient who underwent THA with Platelet-Rich Plasma (PRP) administration.
Conclusion: PRP administration gave a better result to the patient who underwent THA 1 month postoperatively assessed by Harris Hip Score and Berg Balance Scale.
