The Effectiveness of Blood Flow Restriction Technique Combined with Low-Resistance Exercise in the Postoperative Rehabilitation of Patients Following Knee Surgery: A Narrative

Background: Blood Flow Restriction (BFR) therapy has emerged as a promising rehabilitation approach after knee surgery. The technique involves the use of a torniquet or cuff to limit blood flow to the affected limb during low-resistance exercise, which creates a hypoxic environment thought to stimulate muscle growth and improve muscle function. Objective: Our scoping review aims to examine the current literature on the effectiveness of BFR combined with low-resistance exercise on rehabilitation after knee surgery. Method: The Google Scholar, PubMed, and PEDro databases were searched using relevant keywords. Studies that met the inclusion criteria were selected for analysis. The data from the selected studies were analyzed, categorized, and summarized to provide an overview of the findings. Results: A total, 12 studies met the inclusion criteria and were included in the review. Outcomes such as pain, strength, and range of motion were assessed. Conclusion: The results suggest that BFR and low-resistance exercise can be effective in improving patient outcomes following knee surgery. However, the heterogeneity of the studies made it difficult to determine the most effective approach. Further research is needed to identify the optimal dosage, frequency, and duration of BFR and low-resistance exercise for knee surgery rehabilitation.
