SUMMARYPatellofemoral pain (PFP) is a common knee disorder in orthopedic clinics. In the last decade, several investigations have considered the role of proximal factors in addition to local and distal factors in development of PFP. There is a hypothesis which suggests that impaired neuromuscular control and altered hip joint kinematic affect tibiofemoral and patellofemoral biomechanics. Hence, PFP may develop as a result. This article reviews studies assessing the relationship between altered hip mechanics and PFP.The Medline and PubMed databases were searched between January 2004 and October 2014. Two authors independently selected related articles using the same search strategy and key words.Among 149 articles, 16 met the review inclusion criteria. The study results were described in three sections: 1) kinematic studies, 2) muscle activity studies, and 3) postural stability studies.Increased hip adduction and internal rotation, gluteal muscle weakness, and neuromuscular impairment were common findings in patients with patellofemoral pain. Precise assessment of hip mechanics, including hip kinematic, muscle performance and postural stability, should be considered in the examination of patients with patellofemoral pain.

“…Despite the lack of consensus on the causes of this condition, several factors are believed to contribute to its development, such as weakness in the quadriceps (8), changes in the posture alignment of the lower limbs (9), abnormal leg biomechanics, (10), smaller knee flexion angle (11), weak hip muscles (12), excessive adduction and internal rotation of the hip (13) and, primarily, kneecap misalignment (8).…”

Effects of strength training on the treatment of patellofemoral pain syndrome - a meta-analysis of randomized controlled trials

et al. 2017

View full text Add to dashboard Cite

Introduction: Palletofemoral pain syndrome (PFPS) is anterior knee pain that affects around 25% of the population at some point in their lives. Muscle weakness is one of the main causal factors related to PFPS. Objective: Conduct a quantitative analysis on the effectiveness of strength training at reducing pain in PFPS sufferers. Methods: An electronic search was conducted on the MEDLINE, Pubmed, EMBASE, Lilacs and Scielo databases for studies published between January 2005 and September 2014. The following descriptors were used: "patellofemoral pain syndrome", "patellofemoral pain", "retropatellar pain", "exercise", "exercise therapy", "strength", "rehabilitation". Only randomized controlled trials (RCTs) that compared the effects of strength training to no exercise in terms of reducing pain among PFPS sufferers were included. Data were extracted by two independent authors using predefined quality indicators. Results: A total of 39 RCTs were initially identified in the search. However, only five met the inclusion criteria. Strength training exhibited a positive effect on PFPS (SMD = 0.85, CI: 0.45-1.25). However, high heterogeneity was observed between the studies (p < 0.05; I 2 = 68.3%). Conclusion: Strength training showed a statistically positive response in the treatment of PFPS.

“…Deficits in hip muscle strength, activity or hip joint mechanics have been identified in lower limb pathology (Bolgla et al, 2011;Sims et al, 2002;Smith et al, 2014). It is important then, to understand the function of hip muscles in order to facilitate the clinical assessment and rehabilitation of these conditions.…”
