Overview

ACL Tear
An ACL tear is an injury to the anterior cruciate ligament, one of the major ligaments that stabilizes the knee. It commonly occurs during sports or activities involving sudden stopping, changing direction, landing from a jump, or a direct blow to the knee. A tear may cause a popping sensation, pain, swelling, reduced range of motion, and a feeling that the knee is unstable.
Polymyalgia Rheumatica
Polymyalgia rheumatica is an inflammatory disorder that causes pain and stiffness, especially in the shoulders, neck, and hips. Symptoms are often worse in the morning or after periods of rest. It mainly affects adults over 50 and may occur together with giant cell arteritis, which can cause headaches, vision problems, and other vascular symptoms.

Diagnosis

ACL Tear
An ACL tear is diagnosed using the injury history and a physical examination of the knee. Tests such as the Lachman test and other stability maneuvers can indicate ligament injury. MRI may be used to confirm the diagnosis and identify associated damage to the meniscus, cartilage, or other ligaments. X-rays may be performed to check for fractures or other bone injuries.
Polymyalgia Rheumatica
Polymyalgia rheumatica is diagnosed from the pattern of pain and stiffness, medical history, and physical examination. There is no single test that confirms the condition. Blood tests such as erythrocyte sedimentation rate and C-reactive protein may show inflammation. Additional testing may be used to exclude rheumatoid arthritis, other inflammatory disorders, infections, or malignancy.

Prevention

ACL Tear
ACL injuries may be reduced through structured injury-prevention programs that include strength training, balance exercises, agility work, and instruction in safe jumping and landing techniques. Proper warm-up and conditioning are important before sports. Training that improves control of the hips, knees, and core may help reduce excessive forces on the knee during cutting, landing, and sudden changes in direction.
Polymyalgia Rheumatica
There is no known way to prevent polymyalgia rheumatica. Because the condition is associated with giant cell arteritis, people diagnosed with PMR should be aware of new headaches, scalp tenderness, jaw pain while chewing, or visual changes and seek prompt medical evaluation if these occur. Regular follow-up can help monitor symptoms and treatment-related complications.

Risk Factors

ACL Tear
Risk factors include participation in sports involving cutting, pivoting, jumping, or rapid changes in direction, such as football, basketball, soccer, and skiing. Previous knee injury, inadequate conditioning, poor landing or movement mechanics, and muscle weakness may increase risk. Differences in anatomy and neuromuscular control can also influence susceptibility to ACL injury.
Polymyalgia Rheumatica
Polymyalgia rheumatica occurs almost exclusively in adults over 50 and is more common in women. Risk may also be influenced by genetic and geographic factors. Having giant cell arteritis is closely associated with PMR, and people with PMR may develop symptoms of giant cell arteritis. There are no established lifestyle measures known to prevent the disorder.
