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.

To review the etiology of patellar tendinopathy as it relates to clinical management of chronic patellar-tendon disease in athletes.

Data Sources:

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.

Study Selection:

All relevant peer-reviewed literature in English was reviewed.

Data Synthesis:

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.

Overuse injuries are common in basketball. To gain insight into their etiology and relationship to mechanics, researchers and clinicians need an understanding of the normal biomechanics of the sport. This study was undertaken with this goal in mind. Lower extremity joint kinematics and structural parameters were collected from 24 players from five professional basketball teams as they performed maneuvers typical of their sport. The results indicated that certain common moves such as the layup landing resulted in knee flexion velocities almost double those seen during the landing phase of running. Lateral movements such as cutting and shuffling placed the foot in extreme positions of supination. Both of these findings have implications for injuries common to basketball such as patellar tendinitis and ankle sprains. It is hoped that this information will initiate a database for normal lower extremity kinematics during basketball and lead to a greater understanding of the relationship of lower extremity movement patterns and injury.

incidence of injury to runners ranges from 18.2% to 94.4%. 2 The most frequent lesion suffered is that of medial tibial stress syndrome, which has an incidence of 13.6% to 20%. This is followed by Achilles tendinitis, which affects 9.1% to 10.9% of runners, 3 plantar fasciitis (4.5%–10%), and patellar
