Introduction: Patellofemoral pain syndrome (PFPS) is one of the most common causes of anterior knee pain, predominantly affecting physically active individuals and significantly impacting functional ability. It is characterized by retropatellar or peripatellar pain without clearly defined structural changes, and its development can be influenced by various biomechanical and muscular factors. Despite the documented positive effects of exercise on pain reduction and functional improvement, it remains unclear whether strengthening of the knee or hip musculature is the more effective approach. Purpose: The purpose of this thesis was to analyze, through a literature review, the advantages of hip muscle strengthening compared to knee muscle strengthening in patients with PFPS. Methods: A descriptive method was used, based on a review of scientific literature. The literature search was conducted in the PubMed database using the keywords: patellofemoral, knee, hip. Randomized controlled trials comparing knee and hip strengthening exercises in patients with PFPS were included in the review. Results: A total of six randomized controlled trials involving 639 patients with PFPS, with symptoms lasting at least one month, were included in the final analysis. The results indicate that both knee and hip strengthening exercises led to statistically significant reductions in pain and improvements in function and muscle strength. In four studies, no statistically significant differences were found between the two approaches, although two studies reported greater effectiveness of hip or combined training, particularly in reducing pain. Discussion and conclusion: Based on the reviewed literature, both knee and hip strengthening exercises are effective in reducing pain and improving function and muscle strength in patients with PFPS, with no clear superiority of one approach, indicating comparable effectiveness. Hip joint muscles play an important role in controlling the position of the lower limb, as they prevent excessive adduction and internal rotation during functional tasks. Results of individual studies suggest that hip strengthening may be more effective in the early phase of rehabilitation for pain reduction. Therefore, incorporating hip strengthening into rehabilitation programs for PFPS is recommended in clinical practice.
