Amniotic Tissue Injections Are an Effective Alternative to Corticosteroid Injections for Pain Relief and Function in Patients With Severe Knee Osteoarthritis: A Double-Blind, Randomized, Prospective Study.

Introduction: The use of corticosteroid injections for short-term pain relief for knee osteoarthritis can have deleterious adverse effects. Amniotic tissue has shown promise in vitro; therefore, this study compared a morcellized injectable amniotic tissue allograft to corticosteroid injection.

Methods: Eighty-one patients with symptomatic severe knee osteoarthritis (Kellgren-Lawrence grade 3 to 4) were prospectively randomized to either a double-blinded single injection of BioDRestore (Integra LifeSciences; n = 39) or triamcinolone acetonide (n = 42).

Regenesorb and polylactic acid hydroxyapatite anchors are associated with similar osseous integration and rotator cuff healing at 2 years.

Background: Commercially available suture anchors for rotator cuff repairs can differ significantly in architecture and material. Clinical data on their osseous integration and its effect on patient-reported outcomes is scarce. Preclinical investigations indicated a higher rate of osseous integration for the open-architecture design of the Healicoil Regenesorb anchor than the closed-threaded design of the Twinfix (Smith & Nephew).
