Arthroscopic Rotator Cuff Repair With Platelet-Rich Plasma(PRP) in Large to Massive Tears
- The purpose of this study is to compare the clinical and anatomical outcomes of rotator cuff repair with Platelet-Rich Plasma(PRP) and conventional rotator cuff repair in treatment of large to massive rotator cuff tears.
- PRP application to arthroscopic rotator cuff repair would accelerate recovery after arthroscopic rotator cuff repair in terms of pain relief, functional outcomes, overall satisfaction, and enhance structural integrity of repaired tendon.

|Official Title:||Arthroscopic Rotator Cuff Repair With Platelet-Rich Plasma(PRP) in Large to Massive Tears : A Randomized Controlled Trial|
- structural integrity of repaired rotator cuff tendon [ Time Frame: postoperative 9months ]
To evaluate structural outcomes, magnetic resonance(MR)imaging or computed tomography arthrography were used at minimum postoperative 9months.
The structural integrity was evaluated using Sugaya's method;
- type I, sufficient thickness with homogenously low intensity
- type II, insufficient thickness partial high intensity
- type III, insufficient thickness without discontinuity (thinned cuff)
- type IV, presence of minor discontinuity
- type V, presence of a major discontinuity
Type I, II, and III were considered as healed, while type IV, and V were considered as retear.
