Retrospective Analysis of Responders and Impaired Patients with Knee Osteoarthritis Treated with Two Consecutive Injections of Very Pure Platelet-Rich Plasma (PRP).

Objectives: To assess the effectiveness of two consecutive intraarticular injections of PRP to treat knee osteoarthritis (KOA), discriminating between responders and impaired patients.

Methods: This retrospective study included 73 consecutive patients who were referred for two intra-articular PRP injections (one week apart) for treating symptomatic moderate/severe KOA. Biological characterization of the PRP, including platelets, leukocytes and erythrocytes, was evaluated.

High insertion of conjoint tendon is associated with inguinal-related groin pain: a MRI study.

Purpose: To compare the insertions of the conjoint tendon (CT) on MRI in athletes with and without symptoms and to assess their relationship to groin pain with surgery as a reference.

Materials And Methods: Between January and May 2017, patients with inguinal-related groin pain undergoing Shouldice repair were prospectively enrolled and underwent MRI. Exams were independently reviewed by two radiologists blinded to surgical results to assess types of CT insertion as high muscular without (type 1) or with tendinous expansion (type 2) or low muscular (type 3).

Effects of Axial Traction during Direct MR-Arthrography of the Wrist in Sports Injuries.

Purpose: To evaluate the degree of joint distraction during direct MR arthrography with axial traction in sports injuries. To confirm the effect of axial traction on the quality of wrist opacification.

Patients And Methods: Seventeen patients (11 male, 6 female) underwent wrist MR arthrography without (mean: 39 years (SD 11.

Intratendinous injection of platelet-rich plasma under US guidance to treat tendinopathy: a long-term pilot study.

Purpose: To assess the potential therapeutic effect of intratendinous injection of platelet-rich plasma (PRP) under ultrasound (US) guidance to treat tendon tears and tendinosis in a pilot study with long-term follow-up.

Materials And Methods: The study included 408 consecutive patients referred for treatment by PRP injection of tendinopathy in the upper (medial and lateral epicondylar tendons) and the lower (patellar, Achilles, hamstring and adductor longus, and peroneal tendons) limb who received a single intratendinous injection of PRP under US guidance. Clinical and US data were retrospectively collected for each anatomic compartment for upper and lower limbs before treatment (baseline) and 6 weeks after treatment.

Acceleration of tendon healing using US guided intratendinous injection of bevacizumab: first pre-clinical study on a murine model.

Purpose: Tendinopathy shows early disorganized collagen fibers with neo-angiogenesis on histology. Peri-tendinous injection of corticosteroid is the commonly accepted strategy despite the abscence of inflammation in tendinosis. The aim of our study was to assess the potential of intratendinous injection of an anti-angiogenic drug (bevacizumab, AA) to treat tendinopathy in a murine model of patellar and Achilles tendinopathy, and to evaluate its local toxicity.

Rotator cuff tears: should abduction and external rotation (ABER) positioning be performed before image acquisition? A CT arthrography study.

Objective: To evaluate the impact of abduction and external rotation (ABER) positioning performed before image acquisition on the assessment of rotator cuff tears.

Methods: Twenty-seven consecutive patients with clinically suspected rotator cuff tears underwent an initial CT arthrogram of the shoulder in neutral position, immediately followed by temporary ABER positioning, before a second CT acquisition in neutral position. Two observers blinded to potential pre-procedure ABER positioning independently analysed the randomly distributed images.
