3 Clinical Trials for Various Conditions
This pilot study will evaluate the feasibility of pain-guided activity modification during rehabilitation for patellar tendinopathy. The information provided will be utilized to conduct a larger randomized clinical trial to determine if there is a difference in recovery from patellar tendinopathy during rehabilitation between individuals that use pain-guided activity modification and those that halt all painful activities. Recovery from patellar tendinopathy will be assessed using pain ratings, tendon-specific outcome measures, tendon structure, tendon mechanical properties, and muscle function.
Patellar tendinopathy is one of the most frequent causes of non-traumatic knee pain and reduced function in patients. Standard treatment options for patellar tendinopathies include non-steroidal anti-inflammatory drugs, corticosteroids, cryotherapy, manual therapy, eccentric exercises, and ultrasound. Unfortunately many patients fail to respond to these therapies and return to normal activity levels, and recurrence rates for those who do respond are unacceptably high. Many patients who fail to respond display persistent degenerative changes on imaging studies suggesting a failure to regenerate the pathological tissue. Developing new therapies that can directly promote the synthesis of new, healthy extracellular matrix tissue could therefore address an important therapeutic need and make a substantial improvement in our ability to effectively treat patellar tendinopathy and reduce recurrence rates. Somatropin (human growth hormone of recombinant DNA origin) has been shown to increase protein synthesis and matrix production when delivered directly into the tendon. This study will evaluate the ability of somatropin to improve clinical outcomes and tissue quality in patients with chronic tendinopathy.
The goal of this study is to find an effective treatment for chronic patellar tendinopathy (PT). Investigators will conduct a 32-week randomized controlled clinical trial to determine whether platelet rich plasma (PRP) injections improve disease-specific clinical outcomes with correlation to a new method of ultrasound (US) imaging assessment called Acoustoelastography (AE). Positive findings of PRP compared to control would suggest future larger scale studies to help establish an optimal protocol for the nonsurgical management of PT.
