Participating in sports and physical activity comes with the risk of injury. Some of the most common sports injuries include runner's knee, sprained ankles, meniscus tears, rotator cuff tears, and ACL tears. Being aware of the causes, symptoms, and treatments for these injuries can help athletes prevent and recover from them.
Runner's Knee
Runner's knee, also known as patellofemoral pain syndrome, is characterized by pain behind or around the kneecap. It is often caused by overuse, muscle imbalance, and inadequate stretching. Symptoms include pain under or around the kneecap, especially when walking. Treatment focuses on rest, icing the knee, strengthening exercises, stretching, and modifying training.
Sprained Ankle
A sprained ankle happens when the ankle rolls, twists, or turns beyond its normal range of motion, which can tear the ligaments. Symptoms include pain, swelling, and bruising around the ankle. Treatment includes resting the ankle, icing it, compressing it, and elevating it to reduce swelling. Physical therapy exercises can help strengthen the ankle and prevent future sprains.
Meniscus Tear
The meniscus is a piece of cartilage that cushions the knee joint. A meniscus tear occurs when the knee is forcibly twisted, often when bearing full body weight. Symptoms include knee stiffness, swelling, pain, and locking. Minor tears may heal with rest and physical therapy. More severe tears require surgical repair.
Rotator Cuff Tear
The rotator cuff is a group of muscles and tendons that stabilize the shoulder joint. Rotator cuff tears can occur from falls, lifting heavy objects, or overuse. Symptoms include shoulder pain and weakness when lifting or rotating the arm. Rest, pain relief, steroid injections, and physical therapy can help minor tears. Major tears may require surgery.
ACL Tear
The ACL provides stability to the knee joint. It can tear when the knee is forced to suddenly change direction or slow down quickly. Symptoms include severe knee pain, swelling, and loss of full range of motion. Minor tears may heal with bracing and physical therapy. Complete tears require reconstructive surgery to restore knee stability.
Being aware of common sports injuries and their treatments can help athletes stay active while reducing injury risk. Rest, icing, compression, elevation, medication, bracing, physical therapy, and surgery are all options to help the body heal.
