Knee pain may develop from sudden injuries, repetitive strain, or arthritis, affecting joint movement and everyday activities. Although symptoms vary, healthcare providers use physical examinations, medical histories, and imaging tests to identify underlying causes. Treatment options include physical therapy, anti-inflammatory medications, joint injections, and nerve-targeted procedures, which may help manage pain without surgery. Here are a few signs, symptoms, and treatment options for knee pain:
Identifying Causes of Pain
Knee pain may develop from sudden injuries, repetitive movements, or degenerative joint conditions such as arthritis. Although symptoms vary, injuries often affect the ligaments, tendons, cartilage, and other structures that support knee movement. Common causes include:
- Anterior cruciate ligament (ACL) tears
- Medial collateral ligament (MCL) tears
- Meniscus tears
- Patellar instability
- Iliotibial (IT) band injuries
- Patellofemoral pain syndrome
- Patellar tendinitis
- Bone fractures
- Joint dislocations
- Knee bursitis
- Articular cartilage injuries
- Osteoarthritis
Osteoarthritis develops when joint cartilage gradually deteriorates, contributing to stiffness, swelling, and discomfort during movement. Because knee pain has several possible causes, healthcare providers evaluate symptoms and joint function to determine appropriate treatment options.
Diagnosing Pain Conditions
Diagnosing knee pain typically begins with a review of the patient’s medical history, symptoms, and recent injuries. During a physical examination, healthcare providers assess knee stability, range of motion, and areas of tenderness or swelling. Because several conditions cause similar symptoms, these findings help identify potentially affected structures, including ligaments, cartilage, and the meniscus.
Imaging tests provide additional information about the knee joint and surrounding tissues. X-rays help identify fractures, bone alignment changes, and joint space narrowing, while MRI scans provide detailed images of soft tissues. Although not always necessary, CT scans may offer additional views of complex bone injuries. Healthcare providers use these findings to determine the underlying condition and recommend appropriate treatment options.
Treating Pain Nonsurgically
Nonsurgical treatments focus on reducing inflammation, improving joint function, and managing discomfort without invasive procedures. Although treatment depends on the underlying condition, providers often begin with medications, physical therapy, or targeted injections. Common nonsurgical treatment options include:
- Anti-inflammatory medications: Reducing inflammation and discomfort associated with certain knee conditions
- Physical therapy: Strengthening surrounding muscles and improving joint flexibility
- Corticosteroid injections: Providing temporary relief from inflammation and joint pain
- Genicular nerve blocks: Interrupting pain signals transmitted by nerves surrounding the knee
- Platelet-rich plasma (PRP) injections: Using concentrated blood components to support tissue healing, although effectiveness varies
- Radiofrequency ablation: Targeting specific nerves to reduce chronic pain signals
- Peripheral nerve stimulation: Delivering electrical impulses to help manage persistent nerve-related pain
Healthcare providers may use ultrasound or fluoroscopy guidance to improve accuracy when administering certain knee injections. These imaging techniques help identify treatment areas and guide needle placement within or around the joint. Because symptoms and treatment responses vary, providers develop individualized plans based on examination findings and patient needs.
Schedule Your Knee Pain Evaluation
Knee pain may result from injuries, repetitive strain, or arthritis, and identifying the underlying cause helps guide treatment decisions. Although symptoms vary, physical examinations and imaging tests provide information about joint health and potential structural damage. Nonsurgical treatments, including physical therapy, injections, and nerve-targeted procedures, may help manage discomfort and improve mobility. Schedule an evaluation today to discuss your symptoms and explore treatment options that support joint function.
