Minimizing time lost from training and competition due to illness or injury is the priority for professional tennis players and their performance teams. There is a gap in tennis literature investigating injury prevalence in professional tennis players.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Purpose: &lt;/strong&gt;The primary aim of this study was to describe the incidence and prevalence of health conditions in elite tennis players over a full competition year.

The study was undertaken between the 1st January 2023 and 31st December 2023. The study was a retrospective analysis from the injuries and illnesses documented in the weekly meeting of LTA medical and physiotherapy staff as well as using each player's electronic medical records using the computer notes program Sports Office.

The overall incidence of injury and illness was found to be 3.3 per 365 days, 2.1 in males, and 4.4 in females.

Lateral collateral ligament injuries are much less common than those of the anterior cruciate or medial collateral ligament. When they do occur, they are more often associated with posterolateral corner injuries or meniscal injuries. A high index of suspicion is required when examining for lateral knee ligaments. An accurate diagnosis of partial tears or ruptures of the lateral collateral ligament is essential for appropriate treatment planning and optimizing patient outcomes. Diagnostic musculoskeletal ultrasound (MSKUS) offers a portable, real-time, and cost-effective alternative that is gaining traction in rehabilitation and sports medicine settings. MSKUS has emerged as a valuable, non-invasive imaging modality for evaluating ligament injuries, including sprains, partial tears, and ruptures. MSKUS is excellent at detecting changes in ligament composition and continuity. This article will review the utility of MSKUS in evaluating lateral collateral ligament injuries, including anatomy, common injury mechanisms, sonographic techniques, and clinical implications for rehabilitation professionals. Diagnosis of acute ligament injury by physical examination is often challenging and is frequently misdiagnosed.
