Do I Need an MRI If My Knee Catches After Basketball Games?
Yes, an MRI is often recommended because it shows the root cause of your knee locking after activity. These imaging scans provide detailed images of ligaments, cartilage, and soft tissues. This helps your sports medicine physician detect knee conditions such as meniscus tears, ligament injuries, or cartilage damage.
At Total Orthopedics and Sports Medicine, we assess knee catching with specialized tests such as the McMurray’s, Ege’s, and Lachman’s. If these assessments suggest an underlying issue, our doctors may recommend an MRI to obtain a clearer view of the knee’s internal structures. Once the diagnosis is confirmed, we may recommend targeted injections to improve joint function or therapies that stimulate natural healing for lasting recovery.

When Should You Get an MRI for Knee Catching?
You need an MRI if you experience sudden, severe pain, ongoing swelling, visible deformity, or discomfort that lasts longer than three weeks. These warning signs often suggest damage inside the joint that can’t be confirmed through a physical exam. In such cases, an MRI provides detailed images that standard X-rays often miss.
According to Radiopaedia, MRI shows a sensitivity of ~95% for medial meniscal tears and ~85% for lateral meniscal tears. This high level of accuracy makes MRI an essential tool for confirming the source of knee damage, particularly when symptoms like catching, locking, or persistent swelling raise suspicion of internal injury. By identifying tears or loose fragments early, doctors can recommend the most effective treatment plan before the condition worsens.
What Causes Knee Catching in Athletes?
Knee catching often occurs due to meniscus tears, chondromalacia patellae, iliotibial band syndrome, osteochondritis dissecans, and patella subluxation. In some athletes, a Baker’s cyst can also rupture and create a sudden catching or locking sensation. These conditions disturb the normal movement between the thigh bone and shin bone. As the joint becomes less stable, you notice locking, catching, persistent pain, and swelling during activity. Here is how these knee injuries lead to catching sensations:
Meniscus Tears
A tear in the meniscus disrupts normal joint motion, especially when the knee bends. This leads to pain and swelling and may require arthroscopic surgery.
Chondromalacia Patellae
Softening the articular cartilage beneath the kneecap groove causes grinding when you move. That grinding sensation creates discomfort and can feel like the knee giving way.
Iliotibial Band Syndrome (ITBS)
Tightness along the outside of the thigh rubs against the joint with repetitive motion. This friction creates sharp catching pain, especially in athletes who play sports or run regularly.
Osteochondritis Dissecans (OCD)
A small piece of bone or articular cartilage breaks loose and floats inside the joint. These bone and cartilage fragments interrupt smooth motion, often locking the injured knee during activity.
Patella Subluxation
When the kneecap slips partially out of its groove on the thigh bone, the joint immediately becomes unstable. This bone shifting creates a catching sensation and increases the chance of a complete dislocation.
Does Knee Catching Lead to Early Arthritis Development?
Yes, knee catching can sometimes signal the early stages of post-traumatic osteoarthritis. In fact, a study in the Journal of Orthopaedic Trauma shows that in the United States, 12% of all arthritis cases are linked to post-traumatic injuries. When damage such as a meniscus tear or an anterior cruciate ligament (ACL) injury occurs, the joint surface becomes uneven and slowly breaks down. This constant pressure on the injured knee often leads to the early onset of arthritis.
How Does Total Orthopedic & Sports Medicine Treat Knee Catching?
At Total Orthopedics and Sports Medicine, our doctors use advanced imaging tests such as MRI and X-rays, and create treatment plans based on each patient’s condition. We provide conservative treatment options like anti-inflammatory medications and bracing with an elastic bandage to reduce swelling and relieve discomfort. To ensure long-term results, our doctors recommend exercises that strengthen muscles, improve mobility, and help keep the knee stable. We also offer advanced surgical options, including:
- Osteotomy to realign the knee joint.
- Cartilage restoration procedures, such as microfracture or autologous chondrocyte implantation.
- Partial or total knee replacement, depending on the extent of joint damage.
- Anterior cruciate ligament reconstruction for stability in cases of ligament injury.
- Partial meniscectomy to remove damaged meniscus tissue that cannot be repaired.
Many of these procedures can be performed arthroscopically, and Dr. Jarret Boroniec specializes in this minimally invasive technique. Through small incisions, he performs arthroscopy to precisely repair meniscal tears, restore cartilage surfaces, and treat other causes of knee catching. This approach often results in faster recovery, less pain, and minimal scarring compared to traditional open surgery. Contact us today to schedule an appointment.
What’s the Difference Between Knee Catching and Knee Locking?
Knee catching occurs when the joint briefly gets stuck during movement, while knee locking is a complete inability to bend or straighten. Both conditions are linked to underlying knee problems, but locking is the more severe condition. In many cases, knee locking requires immediate medical attention to prevent further damage or other injuries. Here is how knee locking is categorized:
- True locking: The joint is physically blocked, often by a torn meniscus or cartilage flap.
- Pseudo-locking: The knee appears stuck due to pain, swelling, or muscle spasm rather than a block.
To manage these conditions, you must follow targeted exercises that also support long-term knee stability. For knee catching, you can perform wall slides, side-lying hip abduction, and calf raises. Tools like a knee glider support these movements and improve the safe range of motion. In cases of knee locking, doctors suggest hamstring curls and heel slides to restore flexibility. With consistent practice, these exercises help keep the knee stable and support a safe return to normal activity.
Why Do Doctors Prefer MRI Over X-Rays or CT Scans for Knee Injury?
Magnetic resonance imaging (MRI) uses a powerful magnet and radio waves to create detailed images of the knee joint. Unlike X-rays and CT scans, it does not use ionizing radiation, making it a safer option for detecting sports injuries or chronic knee pain. Because it can also produce 3D and cross-sectional views, your doctor can assess knee structural changes.
In addition, doctors often prefer MRI because it reveals both the location and pattern of knee injuries, helping them understand the injury mechanism. These scans effectively detect common knee injuries like ACL tears, medial collateral ligament (MCL), or lateral collateral ligament (LCL), and meniscal injuries. Research published in BMC Musculoskeletal Disorders also reports that MRI achieves about 90.7% accuracy for ACL injuries and 90.4% for PCL injuries, providing reliable data for clinical decisions.
At Total Orthopedic and Sports Medicine, we offer advanced imaging, including X-rays, ultrasound, injections, and open MRI, to assess knee injuries. Our doctors consider your specific symptoms to recommend the imaging test that will give the most accurate and valuable results. Contact us today at 855-321-6784 to schedule your visit.
What Are The Risks Of Delaying An MRI For Knee Pain?
Delaying an MRI for knee pain can lead to worsened pain, reduced mobility, chronic symptoms, and the need for more costly treatments. When injuries such as meniscus tears, tendon injuries, or articular cartilage injuries are not diagnosed early, they may progress and cause long-term damage. Minor injuries that seem mild in the beginning can slowly worsen and develop into chronic pain if the root cause is ignored. Over time, these risk factors may lead to larger tears, knee instability, and tissue flaps that eventually require surgery.

FAQs
Are There Any Risks Associated With Knee MRI Scans?
No, MRI scans do not carry health risks since they rely on magnetic fields rather than radiation. The scan provides detailed images that help doctors assess most knee injuries, including posterior cruciate ligament tears or patellar tendon tears. It also helps doctors choose the right treatment plan based on each patient’s needs.
Can Micro-Tears or Overuse Injuries Cause Knee Catching?
Yes, micro-tears or overuse injuries can cause knee catching because they place stress on the joint’s soft tissues. This repeated stress may irritate the quadriceps tendon or patellar tendon, creating discomfort during movement. Over time, the continuous pressure may cause meniscal tears and jumper’s knee, which are among the most common knee injuries athletes experience.
How Accurate Is MRI at Detecting Meniscus Tears?
MRI for meniscus tears has an accuracy of 85.8%, which makes it a strong diagnostic option. It allows doctors to see the extent of damage and understand whether it relates to a traumatic injury or strain from daily movement. The scan also guides decisions on whether a patient may benefit from rest and therapy or need meniscus repair.
How Long Does It Take to Get Results From a Knee MRI?
Knee MRI results are typically available within 1-2 days, but can take up to a week or more. If doctors suspect a serious problem, some clinics prioritize urgent cases and provide results more quickly. After receiving the images, doctors review them alongside a physical examination to design the most effective treatment plan for recovery.
Are Contrast Dyes Always Needed for Knee MRI Scans?
No, knee MRI scans do not always require contrast dyes. Doctors may recommend contrast when they need a clearer view of soft tissues, especially if pain occurs while trying to bear weight or move a bent knee. In most cases, standard imaging provides enough detail for assessing the quadriceps muscles and surrounding structures.
Can You Get an MRI if Your Knee Is Swollen?
Yes, you can get an MRI if your knee is swollen. It helps identify the extent of the injury and provides detailed images that guide treatment options. In many cases, doctors recommend nonsurgical treatments such as over-the-counter medication, therapy, or lifestyle adjustments. If the injury is more severe, a surgical intervention may be necessary to help patients remain physically active.
Does Your Whole Body Go In for a Knee MRI?
No, you only need to place your lower body inside the machine for the scan. Your upper body stays outside, which often makes the process easier to tolerate. This positioning allows doctors to capture detailed images of the joint while keeping you more comfortable throughout the procedure.
