A knee that locks, catches, or feels as though it gets stuck can be both frustrating and concerning. These symptoms can make everyday activities such as walking, climbing stairs, or getting up from a chair difficult and uncomfortable.
While occasional clicking in the knee is often harmless, persistent locking or catching may indicate an underlying problem that requires assessment and treatment.
What Does Knee Locking Mean?
True knee locking occurs when the knee becomes temporarily stuck and cannot fully bend or straighten. Some people experience complete locking, while others notice a catching sensation or brief episodes where the knee feels as though it is giving way.
These symptoms can occur suddenly or develop gradually over time.
Common Causes of Knee Locking and Catching
Common causes of knee locking and catching include meniscus tears, knee osteoarthritis, loose bodies within the joint, and patellofemoral (kneecap) disorders:
Meniscus Tears
The meniscus is a piece of cartilage that helps cushion the knee joint. A tear can create a flap of tissue that interferes with normal movement, causing locking, catching, or pain.
Knee Osteoarthritis
Arthritis can cause rough joint surfaces, inflammation, and loose fragments within the knee. This may result in clicking, catching, stiffness, and reduced mobility.
Loose Bodies
Small fragments of cartilage or bone can sometimes float within the joint space. These loose bodies may occasionally become trapped between moving surfaces, causing sudden locking episodes.
Patellofemoral Joint Problems
Issues involving the kneecap can sometimes create grinding, catching, or instability during movement.
When Should You Seek Help?
You should seek professional assessment if:
- Locking or catching becomes frequent
- The knee swells regularly
- You experience instability or giving way
- Symptoms limit daily activities
- Pain persists despite rest
Early diagnosis often leads to more effective treatment and can help prevent further joint damage.
Treatment Options
Treatment depends on the underlying cause of the symptoms.
Chiropractic Care and Rehabilitation
Many knee problems benefit from a combination of manual therapy, exercise rehabilitation, and movement correction. Chiropractic care can help improve lower limb biomechanics, joint mobility, muscle balance, and overall movement patterns that may be contributing to knee pain.
Strengthening exercises and activity modification are often important parts of recovery.
MSK Injections
For patients with inflammation, arthritis, or persistent symptoms, ultrasound-guided MSK injection therapies can provide relief.
Depending on the diagnosis, options may include:
- Corticosteroid injections
- Hyaluronic acid injections
- Arthrosamid® injections
- NStride® injections
- Prolozone Therapy
Ultrasound guidance allows precise placement of the injection into the affected structure, helping to maximise treatment effectiveness.
Final Thoughts
A knee that locks or catches should not be ignored, especially if symptoms are becoming more frequent or affecting daily life. Causes range from meniscus tears and arthritis to loose bodies and kneecap problems.
With an accurate diagnosis, many patients respond well to conservative care, chiropractic treatment, rehabilitation, and ultrasound-guided MSK injections. Seeking early assessment can help identify the cause and get you back to moving confidently and comfortably.

Frequently Asked Questions
Knee locking or catching is often caused by a meniscus tear, knee osteoarthritis, loose fragments of cartilage or bone within the joint, or problems involving the kneecap. A proper assessment is important to identify the underlying cause and determine the most appropriate treatment.
Yes. Knee osteoarthritis can lead to inflammation, stiffness, rough joint surfaces, and loose bodies within the joint. These changes can create sensations of catching, clicking, or occasional locking, particularly during movement.
Treatment depends on the cause of the symptoms. Options may include chiropractic care, rehabilitation exercises, activity modification, and ultrasound-guided MSK injections such as corticosteroid, hyaluronic acid, Arthrosamid®, nStride®, or Prolozone Therapy. An assessment can help determine the most effective treatment plan for your condition
