Knee Ligament Injuries
Knee ligament injuries are common, especially among athletes or individuals who engage in activities involving sudden stops, twists, or impacts. These injuries can lead to significant pain, instability, and impaired mobility. At RAD Clinics, we provide effective relief through ultrasound-guided cortisone injections, a minimally invasive treatment option designed to reduce inflammation and alleviate pain.

Causes of Knee Ligament Injuries
Knee ligament injuries are typically caused by:
- Sports or Physical Activities: High-impact sports like football, basketball, and skiing frequently result in ligament injuries.
- Twisting Motions: Sudden changes in direction or twisting the knee can cause strain or tear ligaments.
- Direct Impact: A blow to the knee, such as in contact sports or falls, can damage the ligaments.
- Overuse: Repeated stress or strain can weaken the ligaments over time, making them susceptible to injury.
Symptoms of Knee Ligament Injuries
- Pain and Swelling: Immediate or delayed swelling and pain around the knee.
- Instability: A sensation that the knee may give way or buckle.
- Reduced Range of Motion: Difficulty fully bending or straightening the knee.
- Bruising: Discolouration around the knee may occur following injury.
- Popping Sound: Some individuals may hear or feel a “pop” at the time of injury, especially with ACL tears.
Understanding Knee Ligament Injuries
Ligaments are strong, fibrous bands of tissue that connect bones and provide stability to joints. The knee has four main ligaments:
- Anterior Cruciate Ligament (ACL): Prevents the tibia from sliding too far forward.
- Posterior Cruciate Ligament (PCL): Prevents the tibia from sliding backwards.
- Medial Collateral Ligament (MCL): Provides stability to the inner knee.
- Lateral Collateral Ligament (LCL): Provides stability to the outer knee.
A ligament injury occurs when one or more of these structures are overstretched or torn, often due to sudden movements or trauma.
Diagnosis of Knee Ligament Injuries
Diagnosing knee ligament injuries involves:
- Physical Examination: A clinician will assess the knee for tenderness, swelling, and signs of instability.
- Imaging Tests: MRI scans are commonly used to confirm ligament injuries, as they provide a detailed view of soft tissues.
- Ultrasound: In some cases, ultrasound may be used to assess ligament damage, particularly for superficial ligaments like the MCL and LCL.

Cortisone Injections for Knee Ligament Injuries
At RAD Clinics, we offer ultrasound-guided cortisone injections to manage pain and inflammation associated with knee ligament injuries. This non-surgical treatment option provides targeted relief, allowing you to return to activity faster and with less discomfort.
Benefits of Ultrasound-Guided Cortisone Injections
- Precision: Ultrasound guidance ensures accurate delivery of cortisone to the injured ligament, maximising its effectiveness.
- Pain Relief: Cortisone reduces inflammation in the affected area, providing significant pain relief.
- Reduced Swelling: By controlling inflammation, cortisone helps reduce swelling, promoting a quicker recovery.
- Minimally Invasive: The procedure is non-surgical, involves minimal discomfort, and requires little to no downtime.
What to Expect During the Procedure
- Preparation: You will be positioned comfortably, and the area around the knee will be cleaned.
- Ultrasound Guidance: The clinician uses ultrasound to visualise the injured ligament and precisely guide the injection.
- Injection: A fine needle is carefully inserted into the targeted area, delivering the cortisone.
- Post-Procedure Care: You may experience some initial relief, and the full benefits will typically become noticeable within a few days.
When to Seek Treatment
Consider seeking treatment for knee ligament injuries if you experience any of the following:
- Persistent Pain and Swelling: If pain and swelling do not improve with rest and home remedies, medical treatment may be necessary.
- Instability or Buckling: A feeling that the knee may give way can indicate a serious ligament injury that requires intervention.
- Difficulty with Everyday Activities: Inability to perform daily tasks, such as walking or climbing stairs, suggests the need for further evaluation and possible treatment.
At RAD Clinics, our specialised approach, including ultrasound-guided cortisone injections, provides safe and effective relief for knee ligament injuries, tailored to your needs.
