Six Treatments Have Positive Effects at 3 Months for People With Patellofemoral Pain: A Systematic Review With Meta-analysis.

To determine the effects of nonsurgical treatments on pain and function in people with patellofemoral pain (PFP). Systematic review with meta-analysis. We searched MEDLINE, Web of Science, and Scopus databases from their inception until May 2022 for interventional randomized controlled trials (RCTs) in people with PFP.

Adding muscle power exercises to a strength training program for people with patellofemoral pain: protocol of a randomized controlled trial.

Background: Strong evidence supports the proximal combined with quadriceps strengthening for patellofemoral pain (PFP) rehabilitation. However, most reported rehabilitation programs do not follow specific exercise prescription recommendations or do not provide adequate details for replication in clinical practice. Furthermore, people with PFP have power deficits in hip and knee muscles and it remains unknown whether the addition of power exercises would result in superior or more consistent outcomes.

Telerehabilitation for Knee Osteoarthritis in Brazil: A Feasibility Study.

Background: The effectiveness of telerehabilitation for a patient with knee osteoarthritis may depend upon the person's adherence to intervention. Thus, the aim of this study was to investigate whether people with knee osteoarthritis would adhere to exercise-therapy facilitated via multiple media in Brazil, a newly industrialized country.

Method: This is a feasibility study, pre-post intervention.

Females with patellofemoral pain have impaired impact absorption during a single-legged drop vertical jump.

Background: Females with patellofemoral pain (PFP) have been reported to land with altered biomechanics in some, but not all studies. Kinematic alterations previously reported may indicate, and relate to potential impairments in absorbing impact.

Research Question: To compare vertical ground reaction force (vGRF) and lower limb kinematics during single-legged drop vertical jumps in females with and without PFP; and establish the relationship between vGRF and kinematics during this task.

Clinically measured hip muscle capacity deficits in people with patellofemoral pain.

Objective: To evaluate differences in clinical measures of hip abductor and extensor capacity (strength, endurance and power) in people with patellofemoral pain (PFP) compared to asymptomatic controls.

Design: Cross-sectional.

Settings: Laboratory.

Manifestations of Pain Sensitization Across Different Painful Knee Disorders: A Systematic Review Including Meta-analysis and Metaregression.

Objectives: Previous reviews have reported that manifestations of pain sensitization may play an important role in the pain experienced by people with knee osteoarthritis. However, it is unknown if manifestations of pain sensitization are common features across other painful knee disorders or if sensitization requires targeted intervention. This review aims to synthesize the published research investigating manifestations of pain sensitization in painful knee disorders and to evaluate if the manifestations of pain sensitization change in response to treatment.

Kinesiophobia, but not strength is associated with altered movement in women with patellofemoral pain.

Background: Evidence indicates the presence of both kinesiophobia and knee extension strength deficits in women with patellofemoral pain (PFP). Both impairments may contribute to apparent compensatory gait patterns including reduced cadence and peak knee flexion during stair negotiation.

Research Question: Is kinesiophobia or knee extension strength associated with movement pattern in women with patellofemoral pain?

Methods: Forty women with PFP were assessed with three-dimensional kinematic analyses during stair descent; isokinetic dynamometry of the knee extensors (isometric, concentric and eccentric); and the Tampa scale for kinesiophobia.

Hip rate of force development and strength are impaired in females with patellofemoral pain without signs of altered gluteus medius and maximus morphology.

Objectives: To compare rate of force development (RFD) and isometric muscle strength of the hip abductors and extensors; and the thickness and the amount of non-contractile tissue of the gluteus medius and maximus between females with and without patellofemoral pain (PFP).

Design: Cross-sectional study.

Methods: Fifty-four physically active females (27 with PFP and 27 healthy individuals) were studied.

Proximal mechanics during stair ascent are more discriminate of females with patellofemoral pain than distal mechanics.

Background: Several hypotheses have been proposed to explain the pathomechanisms underlying patellofemoral pain (PFP). Concurrent evaluation of lower limb mechanics in the same PFP population is needed to determine which may be more important to target during rehabilitation. This study aimed to investigate possible differences in rearfoot eversion, hip adduction, and knee flexion during stair ascent; the relationship between these variables; and the discriminatory capability of each in identifying females with PFP.

The 'Best Practice Guide to Conservative Management of Patellofemoral Pain': incorporating level 1 evidence with expert clinical reasoning.

Importance: Patellofemoral pain (PFP) is both chronic and prevalent; it has complex aetiology and many conservative treatment options.

Objective: Develop a comprehensive contemporary guide to conservative management of PFP outlining key considerations for clinicians to follow.

Design: Mixed methods.
