Özet
Objective To compare 12-month outcomes of single-session arthrocentesis with intra-articular injectable platelet-rich fibrin (i-PRF) in temporomandibular joint osteoarthritis (OA) vs disc displacement without reduction (DDWOR). Study Design Single-center retrospective cohort of 89 consecutive patients (OA = 48, DDWOR = 41) treated by one surgeon. Methods Double-needle lavage (∼100 mL saline) followed by intra-articular i-PRF (∼1.5 mL). Primary outcomes were pain on function (0-100 visual analog scale) and maximum interincisal opening (mm) measured at baseline (T0) and 12 months (T1). Two-tailed tests (α = 0.05) and Cohen’s d were used. Results Both groups improved significantly at T1 ( P < .001). OA showed greater relative pain reduction (−66.4% vs −52.5%; d≈0.50), whereas DDWOR achieved larger functional gains (ΔMIO 5.34 vs 2.71 mm; +19.7% vs +8.8%; d≈0.77-0.84). Conclusions Arthrocentesis plus i-PRF yields clinically meaningful 12-month improvements in both conditions, with greater pain relief in OA and greater mouth-opening gains in DDWOR, supporting individualized, goal-oriented TMJ management.
