Common Knee Sports Injuries in Texas

The knee is a finicky joint, and not difficult to injure. Sports-related knee injuries often result from poor strength conditioning, overburdening the joint, poor nutrition (which leads to weakened joints), and sudden movements that place unexpected stress on the knee. 

When knee injuries happen, you need to visit a sports knee injury specialist for urgent care. Sunnyvale Sports Medicine and Orthopedic Surgery Center customizes your treatment to get you back in the game asap – because no one joins the team to warm the bench. 

Texas Children’s Hospital reports that two of young athletes’ most common sports injuries happen to the knee.  

  • Torn Anterior Cruciate Ligament (ACL) is the second-most common sports injury. Athletes can twist or collide the outside of their knee, then hear a “pop” and experience swelling and stiffness.   
  • Another common knee problem or sports injury among Texas athletes is a torn meniscus. Athletes might hyper-extend or twist their knee and feel a tearing sensation, then experience sudden, painful swelling. A torn meniscus may need surgery, although some younger athletes (under age 15) may recover without surgery.  

Athletes who experience any of these symptoms need evaluation from a specialist for knee injury to determine the exact knee condition, type of injury, and the best course of treatment.

The knee connects the leg’s upper and lower structures. It’s a key weight-bearing joint and needs to be stable to carry your body weight comfortably.  

The knee joint mostly moves backward and forward, although it also rotates slightly. We use it for daily functions like walking, standing up, and climbing stairs.  

Many athletic movements, including running, jumping, and changing direction suddenly, place increased pressure on the knee. Vigorous and demanding activities bring you greater knee injury risk.  

Knee Bones

  • Femur ("thigh bone”)  
  • Patella (“kneecap”) 
  • Tibia (“shin bone”)

Knee Muscles

  • Quadriceps (front of the thigh) 
  • Hamstrings (back of the thigh) 
  • Calf & lower-leg muscles (gastrocnemius and soleus) 

Knee Ligaments

Ligaments attach bones to one another, allowing bones to move fluidly each other in the joint. The main ligaments of the knee include:   

  • Anterior cruciate ligament (ACL) stabilizes the knee’s anterior (front) 
  • Posterior cruciate ligament (PCL) stabilizes the knee’s posterior (back) 
  • Lateral collateral ligament (LCL) stabilizes your knee’s side-to-side movement 
  • Medial collateral ligament (MCL) stabilizes underneath your patella/knee cap  

Knee Cartilage

Cartilage protects the ends of bones from friction. The knee’s main cartilage is the meniscus, which is divided into two crescent-shaped pieces.   

A diagnosis from a knee injury specialist provides the best solutions for your specific knee pain.

Knee Injuries Explained

Whatever the cause of your knee pain or injury, allow an experienced knee pain specialist to treat itDon’t settle for anything less. 


Orthopedic surgeons are medical doctors who specialize in the diagnosis, treatment, and restoration of musculoskeletal ailments. Knee doctors deal with knee bones and joints. Aside from the knees, Dr. Hibbitts has focused his specialized practice on the body’s most critical joints – shoulders, hips, and ankles – and offers both surgical and nonsurgical joint treatment options.


A strain occurs by overstretching, overusing, or bruising a knee’s muscles or tendonsAthletes with impaired balance or coordination and those with leg muscle weakness or inflexibility are at risk. 

Knee Fractures

A fracture happens when the knee’s bones are partially or completely broken. A sudden impact is the most common cause of a fracture near the knee joint.  

Knee Dislocation

A dislocation occurs when the knee bones do not align properly, the patella is out of place, or the tibia or femur do not align with the rest of the joint. 


“Bursitis” happens with inflammation or irritation of the bursae -- the fluid-filled sacs that cushion your joints. Arthritis can cause bursitis, and bursitis can make arthritis worse.  


Tendonitis occurs when tendons become irritated, often causing swelling and tenderness. Repeated movement, overuse, or a sudden injury such as twisting, pulling, or straining the knee can cause tendonitis. 

Quad Tendon Repair

The tendon attaching the quadriceps and patella can partially or completely tear. A surgeon may insert a quad tendon graft using the patient’s own tissue or reattach the tendon by anchoring the detached muscle to the patella with sutures.  

Meniscus Tears & Transplants

Tearing the meniscus cartilage results in pain, swelling, and instability, often causing the knee to “give out.” Sudden twisting or hyperextension of the joint can tear the meniscus, which is frequently accompanied by a “popping” sound.  

During meniscus transplant surgery, a knee injury specialist replaces the injured or worn-away meniscus cartilage with donor tissue.    

ACL Tear Surgery, Grafting, & Repair

A tear in the Anterior Cruciate Ligament (ACL) results in pain, inflammation, and the knee’s inability to bear weight, often accompanied by a “popping” sound and sensation. A sudden impact or a stressful movement such as a hyper-extension or severe twisting can detach the ACL partially or completely from the femur and tibia.  

During ACL tear surgery, knee surgeons repair the torn ligament by grafting the patient’s tissue or tissue from a donor onto the detached area, securing the femur to the tibia using surgical sutures. Graft options for ACL reconstruction include harvesting ligament tissue from the patient’s patellar, hamstring, or quadriceps ligaments, or using cadaver donor ligaments. 

CL Cartilage Surgery & Grafting

In the back, the posterior cruciate ligament (PCL) and nearby cartilage stabilize the knee. A sudden frontal injury that hyper-extends the knee causes damage that requires surgery. Even without injury, long-term damage to the cartilage results in knee instability and weakness. A cartilage transplant graft surgery alleviates ongoing damage to the interior soft tissues in the knee.   

Patellar Instability Correction (Subluxation & Dislocated Patella Repair)

A “luxating patella” results when the patella (or “kneecap”) dislodges from its position in the groove at the front of the femur. A partial dislodge is called “subluxation,” and a complete dislodge is called a “dislocation.” Sudden impact, twisting, or pulling on the leg can cause patella instability.  

MCL, PCL, & LCL (Collateral Ligament) Reconstruction & Repair

Tears in the other ligaments of the knee – the MLC, PCL, and LCL – are less common than ACL tears; however, they should all be treated by a knee pain specialist. Known as “collateral ligaments,” these supporting structures provide essential knee stabilization from every direction. 

During a collateral ligament reconstruction procedure, the orthopedic surgeon will surgically reattach the damaged ligament using specialized surgical sutures or grafted ligament tissue from the patient or a donor. 

Untreated knee injuries result in reduced mobility, decreased life enjoyment, and long-term disability. If you experience a knee injury, visit a knee injury specialist right away to avoid complications and chronic issues. 

Indications of Knee Injury

Knee Pain that Indicates You Should See a Knee Injury Specialist

Do not self-diagnose a knee injury. Athletes who don’t seek medical attention from a sports knee injury specialist can suffer ongoing ailments. To recover fully, don’t ignore joint pain, knee arthritis, or other symptoms.

Knee injury doctors are trained to know how to best treat your knee pain and restore function. If you experience any knee injury symptoms, please make an appointment with the Sunnyvale Sports Medicine and Orthopedic Center.  

Common knee injury symptoms: 

  • Stiffness, decreased range of motion, & immobility 
  • A “pop” or “snap” sound or sensation 
  • Decreased function, including the inability to bear weight 
  • Pain, especially radiating down or up the leg 
  • Swelling and inflammation 

These symptoms indicate that you may need immediate knee treatment from a specialist in knee injuries. 

Diagnosing Knee Injuries for Treatment

During your diagnosis, Dr. Hibbitts, knee injury specialist, may utilize several techniques to determine your best course of treatment.   

  • X-rays: Provides images of your bones. 
  • Magnetic Resonance Imaging (MRI): Provides images of the soft tissues (ligaments, tendons, & cartilage).  
  • Arthrocentesis (fluid sample): Provides information about bursae.  
  • Blood tests: Provide information about infections. 

A thorough diagnosis is crucial to customize your treatment and support your full recuperation. As a specialist for knee injury, Dr. Hibbitts uses a full assessment process to determine the best course of action for you, getting you back in the game as soon as possible.
