What to know
Soft tissue injuries affect structures such as muscles, tendons, and ligaments. A sudden blow or twisting force can cause a sprain, strain, or bruise. These injuries can hurt and limit function even when an X-ray does not show a broken bone. AAOS soft tissue injury guide, RadiologyInfo bone X-ray guide
Understanding the terms
A sprain is an injury to a ligament, which connects bones at a joint. A strain affects a muscle or tendon. A contusion is a bruise caused by impact. The severity can range from overstretching to a more substantial tear. AAOS injury definitions
The knee meniscus is different: it is fibrocartilage that helps cushion the joint. A torn meniscus can cause swelling, catching, locking, or a feeling that the knee may give way. Being able to walk does not rule it out. AAOS meniscus guide
Why a normal X-ray may not explain your pain
X-rays provide useful bone images but limited detail about many soft tissues. Depending on the suspected injury, MRI or ultrasound may answer a different clinical question. Additional imaging is selected for a reason; it is not automatically necessary for every painful joint. RadiologyInfo imaging limitations
For knee symptoms, a clinician may examine tenderness, motion, and signs of a meniscus injury before recommending imaging. An MRI can show structures that are not visible on a routine X-ray. AAOS meniscus evaluation
Describing what has changed
Prepare examples of lost function: a knee that catches on stairs, a shoulder that prevents reaching overhead, or a wrist that hurts when gripping. Note swelling, the timing of symptoms, and any earlier problem in the same area.
Treatment depends on the tissue and severity. It may involve protection, activity changes, rehabilitation, or specialist treatment. Significant tears can require a different approach from a mild strain. AAOS soft tissue treatment guidance
Next steps
For persistent non-emergency joint or soft tissue symptoms, explore SpineLUX orthopedic care or call 972-920-9111. Sudden loss of circulation, major deformity, or another emergency requires immediate care.
Common questions
Frequently asked questions
Can a meniscus tear be called a torn ligament?+
No. The meniscus is cartilage; ligaments are separate structures.
What should I ask at follow-up?+
Ask what diagnosis best explains the symptoms, which activities are safe, and what improvement should look like before your next visit.
Do X-rays show soft tissue damage?+
No. X-rays mainly show bone, so a normal film does not rule out a ligament, tendon, muscle, or disc injury. Those structures may need MRI or ultrasound when a clinician decides that study is appropriate. The choice depends on the examination and the question the image should answer. Imaging is not automatic after every sprain, and recommendations depend on clinical evaluation.
