Confirmatory factor analysis of VISA-P scale and measurement invariance across sexes in athletes with patellar tendinopathy.

J Sport Health Sci 2017 Sep 22;6(3):365-371. Epub 2016 Jan 22.

Department of Basic Psychology and Methodology, University of Murcia, Murcia 30100, Spain.

Background: The Victorian Institute of Sport Assessment-Patella (VISA-P) scale is the most condition-specific patient-reported outcome measure used to assess symptom severity in athletes with patellar tendinopathy. Previous exploratory factor analyses have been conducted to evaluate the scale's dimensionality, with inconsistent results, and the factor structure of the scale remains unclear. The aims of the present study were to determine the factorial structure of the VISA-P scale using confirmatory factor analysis (CFA) and test measurement invariance across sexes. Read More

Authors:
Keith Baar

Int J Sport Nutr Exerc Metab 2019 Feb 4:1-5. Epub 2019 Feb 4.

1 University of California Davis.

Patellar tendinopathy is one of the most common afflictions in jumping sports. This case study outlines the rehabilitation of a professional basketball player diagnosed by magnetic resonance imaging (MRI) with a central core patellar tendinopathy within the proximal enthesis. The player undertook a nutrition and strength-based rehabilitation program combining gelatin ingestion and heavy isometric loading of the patellar tendon designed to produce significant stress relaxation as part of their competition schedule and a whole-body training plan.

J Orthop Sports Phys Ther 2018 Sep 23;48(9):676-684. Epub 2018 May 23.

Background Investigations on the causes of patellar tendinopathy should consider impairments at the hip and foot/ankle because they are known to influence movement patterns and affect patellar tendon loading.

Freiburg University Hospital, Clinic of Orthopedic Surgery and Traumatology, Hugstetter Str. 55, 79098, Freiburg, Germany.

Background: The prevalence of patellar tendinopathy is elevated in elite soccer compared to less explosive sports. While the burden of training hours and load is comparably high in youth elite players (age < 23 years), little is known about the prevalence of patellar tendinopathy at this age. There is only little data available on the influence of age, the amount of training, the position on the field, as well as muscular strength, range of motion, or sonographical findings in this age group.

Because tendinopathy is difficult to treat and has negative effects on the ability to work and quality of life, development of preventive interventions is important. The first step in the Van Mechelen prevention model is to determine the extent of the problem. Read More

Do isometric and isotonic exercise programs reduce pain in athletes with patellar tendinopathy in-season? A randomised clinical trial.

J Sci Med Sport 2016 Sep 7;19(9):702-6. Epub 2015 Dec 7.

Monash University, School of Physiotherapy, Australia.

Objectives: Many athletes with patellar tendinopathy participate in sports with symptoms during or after activities. Current treatments do not decrease pain in-season; eccentric exercises in-season result in an increase in pain. This study examined if isometric and isotonic exercises relieved pain in competing athletes with patellar tendinopathy. Read More

Prospective Study of the Relation between Landing Biomechanics and Jumper's Knee.

Int J Sports Med 2016 Mar 23;37(3):245-50. Epub 2015 Dec 23.

Department of Rehabilitation Medicine, University of Groningen, University Medical Center, Groningen, Netherlands.

The literature on the relation between jump biomechanics and jumper's knee indicates that a jump with horizontal displacement poses a threat for developing jumper's knee. Subjects with jumper's knee have been shown to display a stiff landing pattern characterized by a small range of motion. However, up to now only cross-sectional studies have been conducted.

Lower Extremity Kinematics During a Drop Jump in Individuals With Patellar Tendinopathy.

Orthop J Sports Med 2015 Mar 18;3(3):2325967115576100. Epub 2015 Mar 18.

University of Georgia, Athens, Georgia, USA.

Background: Patellar tendinopathy (PT) is a common degenerative condition in physically active populations. Knowledge regarding the biomechanics of landing in populations with symptomatic PT is limited, but altered mechanics may play a role in the development or perpetuation of PT.

Purpose: To identify whether study participants with PT exhibited different landing kinematics compared with healthy controls. Read More

Editorial Commentary: Arthroscopy Is Preferred Over Open Surgery for Patellar Tendonitis.

Authors:
James H Lubowitz

Arthroscopy 2015 Dec;31(12):2430

Jumper's knee is generally managed without surgery, but for patellar distal pole or midsubstance tendonitis (or tendinosis), if surgery is indicated, arthroscopic surgery is as effective as open, with faster return to play. Read More

Muscle and tendon adaptation in adolescent athletes: A longitudinal study.

Scand J Med Sci Sports 2017 Jan 8;27(1):75-82. Epub 2015 Dec 8.

Department of Training and Movement Sciences, Humboldt-Universität zu Berlin, Berlin, Germany.

There is evidence that a non-uniform adaptation of muscle and tendon in young athletes results in increased tendon stress during mid-adolescence. The present longitudinal study investigated the development of the morphological and mechanical properties of muscle and tendon of volleyball athletes in a time period of 2 years from mid-adolescence to late adolescence. Eighteen elite volleyball athletes participated in magnetic resonance imaging and ultrasound-dynamometry sessions to determine quadriceps femoris muscle strength, vastus lateralis, medialis and intermedius morphology, and patellar tendon mechanical and morphological properties in mid-adolescence (16 ± 1 years) and late adolescence (18 ± 1 years).

State-of-the-art ultrasonographic findings in lower extremity sports injuries.

J Med Invest 2015 ;62(3-4):109-13

Department of Orthopedics, the University of Tokushima.

Athletes sometimes experience overuse injuries. To diagnose these injuries, ultrasonography is often more useful than plain radiography, computed tomography (CT), or magnetic resonance imaging (MRI). Ultrasonography can show both bone and soft tissue from various angles as needed, providing great detail in many cases. Read More

Rehabilitation of Patellar Tendinopathy Using Hip Extensor Strengthening and Landing-Strategy Modification: Case Report With 6-Month Follow-up.

J Orthop Sports Phys Ther 2015 Nov 21;45(11):899-909. Epub 2015 Sep 21.

Study Design Case report. Background Although eccentric exercises have been a cornerstone of the rehabilitation of athletes with patellar tendinopathy, the effectiveness of this intervention is sometimes less than ideal. Athletes with patellar tendinopathy have been shown to have different jump-landing patterns and lower hip extensor strength compared to asymptomatic athletes. Read More

Center for Sports Medicine, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.

Numerous athletes with patellar tendinopathy (PT) use a patellar strap or sports tape during sports. This study's aim was to investigate the short-term effect of these orthoses on patellar tendon pain. Participants performed the single-leg decline squat, vertical jump test, and triple-hop test under four different conditions (patellar strap, sports tape, placebo, and control). Read More

The effect of a patellar strap on knee joint proprioception in healthy participants and athletes with patellar tendinopathy.

J Sci Med Sport 2016 Apr 14;19(4):278-82. Epub 2015 May 14.

University of Groningen, University Medical Center Groningen, Center for Sports Medicine, P.O. Box 30 001, 9700 RB Groningen, The Netherlands.

Objectives: The primary aim of this study is to investigate the effect of the use of a patellar strap on knee joint proprioception in both healthy participants and in patients with patellar tendinopathy (PT). Secondary aims are to examine whether there is a difference in effectiveness of the use of a patellar strap between participants with low and high proprioceptive acuity and if possible predictors of effectiveness can be determined.

Design: Case-control. Read More
