Athletes who tested positive for a COVID-19 infection were more likely to suffer a concussion within 60 days of recovering from the infection than athletes who did not contract COVID-19.

Background

COVID-19 affects the respiratory, cardiovascular and nervous systems. In some cases, COVID-19 can lead to long-term consequences (e.g. impaired cognition). It is currently unknown whether COVID-19 infection affects the risk of sports-related concussions.

Study aim

Bullock and colleagues completed a prospective cohort study to compare concussion rates between high school athletes who recently tested positive for COVID-19 and those who did not.

Methods

The authors recruited athletes from high schools in six states. A certified athletic trainer recorded all cases of COVID-19 infection or concussion. If an athlete reported COVID-like symptoms or had an elevated temperature during a daily screening, the athletic trainer administered a COVID test. The research team also recorded when an athlete participated in a training or competition. The authors focused on the number of concussions within 60 days after an athlete returned to play following a COVID-19 infection. All data was recorded in the Players Health Rehab system, including demographic information, sports and illness data for all athletes.

Results

A total of 72,522 athletes participated in high school sports at the affected school during the 2020-2021 school year. Of these athletes, 430 had COVID-19 infections. Of the athletes with a COVID-19 infection, 32 had a concussion, and 1,241 athletes without COVID-19 had a concussion. An athlete with a history of COVID-19 was approximately 3 times more likely to suffer a concussion within 60 days of returning to play than an athlete without COVID-19.

Viewpoints

Overall, the authors found that prior COVID-19 infection increased the risk of concussion during the first 60 days after recovery from COVID-19. Therefore, the effects of a COVID-19 infection may linger after returning to play. Knowing whether this applies to other sports-related injuries would be interesting. Additionally, learning why these athletes are at greater risk for concussion (e.g., deconditioning, persistent symptoms) can help us develop prevention strategies and make informed decisions about when and how to release an athlete to play following a COVID-19 infection.

Clinical implications

Doctors should explain to patients with COVID-19 that they may experience lingering effects that predispose them to concussion. We need to help the patient make an informed decision about when to return to play after COVID-19 infection. Once an athlete returns, doctors should monitor these patients for concussions.

Questions for discussion

What other measures have you implemented in your clinical practice to monitor athletes after COVID-19 infection? Is a COVID-19 infection something you are currently documenting?

    Knee replacement age limit

    Is there a magic number that determines when you’re too old for a joint procedure? This is one of the most common questions we hear from individuals struggling with persistent pain. Many believe a strict cutoff exists. In reality, the decision for this surgical intervention is far more nuanced. Nearly one million of these procedures are performed each year in the United States. knee replacement age limit discussion We find the timing is based on your unique health profile, not just the calendar. Your specific joint condition and how it impacts your daily mobility are the true guides. While concerns about being “too old” are frequent, we see successful outcomes across a wide spectrum of years. The focus should be on your overall wellness and the level of disability you’re experiencing. Key Takeaways There is no universal, strict age cutoff for considering a joint procedure. The decision is highly individual, based on health and lifestyle factors. Successful outcomes are achieved for patients of various ages. Your specific level of pain and disability is a more critical factor than your birth year. Nearly one million of these surgeries are performed annually in the U.S. A consultation focuses on your overall wellness, not just a number. Understanding Knee Replacement Surgery When pain from joint degeneration becomes debilitating, many consider surgical intervention as a viable solution. This procedure, formally called arthroplasty, removes damaged bone and cartilage. Artificial implants are then secured to restore smooth movement. understanding knee replacement surgery What Is Knee Replacement? Arthroplasty is a major operation performed by orthopedic specialists. During this surgery, the ends of the thigh and shin bones are reshaped. Metal and plastic components are fixed in place to create a new joint surface. The goal is to eliminate discomfort and improve mobility. According to Toni Golen, M.D., and Hope Ricciotti, M.D., these artificial joints typically function well for 15 to 20 years. This durability influences the timing of the operation. Who Are the Ideal Candidates? We identify suitable candidates based on several key factors. The severity of arthritis discomfort is a primary consideration. Individuals whose chronic pain persists despite medications or injections are often good candidates. Doctors also examine how the joint has deteriorated over time. When non-surgical options no longer provide relief, this procedure may be recommended. Research shows 80% to 90% of individuals report positive outcomes after their operation.

Medical Factors Beyond Age Medical professionals look beyond the calendar to evaluate a person’s fitness for a major joint operation. Your specific health profile and daily function are the true guides.
