Professional tennis players suffer high prevalence of shoulder alterations during the season: a possible tennis shoulder syndrome.

Purpose: To analyze the shoulder alterations of professional tennis players during the competition season and to compare the differences between their dominant vs. non-dominant shoulders, as well as gender and age differences.

Methods: Two-hundred and seventy shoulders of (78 men and 57 women) professional active tennis players were assessed during 3 ATP and WTA tournaments.

Fabella syndrome in an elite swimmer.

The fabella is a sesamoid bone present in 30% of the population and, in the majority of cases, it is shown in the proximal head of the lateral gastrocnemius articulating with the lateral femoral condyle. Fabella syndrome is an uncommon disease and it must be considered when dealing with posterolateral pain that increases with extension of the knee. Because of its rarity and underdiagnosis, the literature reports few articles relating to its therapeutic management.

Quadriceps tendon autograft and platelet rich plasma injection to treat chronic Achilles tears-a minimum two-year follow-up.

Background: The possibility of using a bone-tendon quadriceps tendon graft and platelet rich plasma (PRP) injection to enhance healing capability, to solve the defect created by stump retraction in chronic Achilles tendon ruptures was studied in a series of 8 patients.

Methods: A series of 8 patients studied prospectively and followed for more than 24 months is presented. Results were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) score, and evaluating pain, level of activity, footwear restrictions, and satisfaction.

Quadriceps autograft to treat Achilles Chronic tears: a simple surgical technique.

Background: Chronic Achilles tendon tears could hinder patients and represent a challenge to surgeons. Although many different surgical techniques have been proposed for reconstruction of a neglected Achilles tendon rupture, there is no clear evidence to support one technique over the others, but the use of a technique that could allow for an "anatomical" reconstructions seems desirable.

Methods: The present paper describes a new anatomic Achilles tendon reconstruction for chronic tears, using a quadriceps tendon autograft as graft source, with PRP injected into the graft and the neighbor tissue, and fixation in a bone trough with a simple small fragments screw.
