BACKGROUND Chronic Achilles tendinosis is a common musculoskeletal disorder often refractory to conservative management. Our study aimed to assess the safety and efficacy of the use of autologous skin-derived collagen-producing cells in the treatment of refractory Achilles tendinosis. METHODS We conducted a randomized, double-blind study on forty Achilles tendons in thirty-two patients (eight...

BACKGROUND Ultrasound (US) elastography can provide information about the hardness of calcification and might help decide treatment strategy. The purpose of this study was to evaluate the hardness of the calcific area within rotator cuffs by US elastography as an aid for the selection of aspiration or fine-needle repeated puncture for the treatment of rotator cuff calcific tendinosis. METHODS...

We describe the use of ultrasound guidance for hyperosmolar dextrose (prolotherapy) injection of the distal calcaneal tendon specifically just anterior to identified enthesophytes in patients with insertional Achilles calcific tendinosis refractory to conservative treatment. This specific technique has not to our knowledge been described or used in literature previously.

BACKGROUND Elbow epicondylar tendinosis is a common problem that usually resolves with nonoperative treatments. When these measures fail, however, patients are interested in an alternative to surgical intervention. HYPOTHESIS Treatment of chronic severe elbow tendinosis with buffered platelet-rich plasma will reduce pain and increase function in patients considering surgery for their problem....

It has been shown that 12 weeks of eccentric heavy resistance training can reduce pain in runners suffering from chronic Achilles tendinosis, but the mechanism behind the effectiveness of this treatment is unknown. The present study investigates the local effect of an eccentric training regime on elite soccer players suffering from chronic Achilles tendinosis on the turnover of the peritendinou...

BACKGROUND Tendinosis lesions show an increase of glycosaminoglycan amount, calcifications, and lipid accumulation. Therefore, altered cellular differentiation might play a role in the etiology of tendinosis. This study investigates whether adolescent human tendon tissue contains a population of cells with intrinsic differentiation potential. METHODS Cells derived from adolescent non-degenera...

PURPOSE The goal of the present study was to compare the patellar tendon cross-sectional area with the patellar tendon thickness and to determine the intra-observer compliance level in the cross-sectional area and thickness measurements. This comparison was used to describe the effects of playing volleyball on the patellar tendon. MATERIALS AND METHODS The patellar tendons of 60 volleyball pl...
