To review the etiology of patellar tendinopathy as it relates to clinical management of chronic patellar-tendon disease in athletes.
Information was gathered from a MEDLINE search of literature in English using the key words patellar tendinitis, patellar tendonitis, patellar tendinosis, patellar tendinopathy, and jumper’s knee.
All relevant peer-reviewed literature in English was reviewed.
The etiology of patellar tendinopathy is multifactorial, incorporating both intrinsic and extrinsic factors. Age, muscle flexibility, training program, and knee-joint dynamics have all been associated with patellar tendinopathy. The roles of gender, body morphology, and patellar mobility in patellar tendinopathy are unclear.
The pathoetiology of patellar tendinopathy is a complex process that results from both an inflammatory response and degenerative changes. There is a tremendous need for research to improve our understanding of the pathoetiology of patellar tendinopathy and its clinical management.

To compare outcomes of 2 rehabilitation protocols on patellar tendinitis subjects.
Prospective, randomized, blinded, controlled clinical trial.
Outpatient rehabilitation clinic.
Randomized into 2 rehabilitation groups—traditional (n = 10) and ASTM AdvantEDGE (n = 10).
Main Outcome Measures:
Clinical data and self-reported questionnaires collected at 0, 6, and 12 weeks.
On completion of the 6th week, 100% of the ASTM AdvantEDGE group and 60% of the traditional group had resolved. The unresolved subjects were crossed over to the ASTM AdvantEDGE for additional therapy. At the end of the additional therapy, 50% of the crossover subjects had resolved. The ASTM AdvantEDGE group's clinical outcomes and weekly journals indicated a statistically significant (P = .04) improvement in subjective pain and functional-impairment ratings.
Findings suggest that ASTM AdvantEDGE resulted in improved clinical outcomes in treating patellar tendinitis.
