Development of patellofemoral pain syndrome (PFPS) is considered to be
multifactorial. The aims of this systematic review were to (i) summarise and
critique the body of literature addressing kinematic gait characteristics
associated with PFPS; and (ii) provide recommendations for future research
addressing kinematic gait characteristics associated with PFPS. A comprehensive
search of MEDLINE, EMBASE, CINAHL, and Current Contents revealed 561 citations
for review. Each citation was assessed for inclusion and quality using a modified
version of the 'Quality Index' and a novel inclusion/exclusion criteria checklist
by two independent reviewers. A total of 24 studies were identified. No
prospective studies with adequate data to complete effect size calculations were
found. Quality of included case-control studies varied, with a number of
methodological issues identified. Heterogeneity between studies made
meta-analysis inappropriate. Reductions in gait velocity were indicated during
walking, ramp negotiation, and stair negotiation in individuals with PFPS.
Findings indicated delayed timing of peak rearfoot eversion and increased
rearfoot eversion at heel strike transient during walking; and delayed timing of
peak rearfoot eversion, increased rearfoot eversion at heel strike, reduced
rearfoot eversion range, greater knee external rotation at peak knee extension
moment, and greater hip adduction during running in individuals with PFPS. There
is a clear need for prospective evaluation of kinematic gait characteristics in a
PFPS population to distinguish between cause and effect. Where possible, future
PFPS case-control studies should consider evaluating kinematics of the knee, hip
and foot/ankle simultaneously with larger participant numbers. Completing between
sex comparisons when practical and considering spatiotemporal gait
characteristics during methodological design and data analysis is also
recommended.
