Abstract

Update This article was updated on January 25, 2024 because of a previous error. John Hodges, DPT should be listed as Jonathan J. Hodges, DPT. An erratum (JBJS Case Connect. 2024;14[1]:e23.00422ER) has been published for this article. Case: This is the first documented case of an isolated traumatic vastus medialis rupture that occurred in a 14-year-old athlete after direct impact during play. Imaging confirmed a rare mid-substance rupture. The patient underwent conservative management with physical therapy augmented by blood flow restriction therapy (BFRT) and platelet-poor plasma (PPP) injection to regain full function. Conclusion: Isolated quadriceps mid-substance tears are rare. Determining an appropriate treatment technique for mid-substance tears is complex. This case documents the use of nonoperative management with BFRT and PPP to achieve full recovery and early return to play in a young athlete.
