Causes & Symptoms
Clinical Causes: Traumatic injuries such as sports accidents or falls that stretch or tear the knee ligaments Repetitive stress or overuse leading to ligament laxity Degenerative joint diseases like osteoarthritis causing weakening of knee structures Previous knee surgeries or injuries that weaken the internal structures Genetic predispositions affecting ligament strength or joint stability
Key Symptoms: A sensation of the knee giving way or feeling unstable Snapping or popping sounds during movement Persistent or intermittent knee pain Swelling around the knee joint Difficulty fully extending or bending the knee Tenderness over the affected area Visible or palpable ligament laxity leading to joint looseness
Diagnostic & Treatment
Diagnosis Path: Diagnosing internal derangements of the knee involves a combination of clinical evaluation and imaging techniques. Healthcare providers perform physical examinations to assess joint stability, check for loose or tender areas, and observe movement patterns. Imaging studies such as MRI scans are particularly useful for visualizing soft tissue structures, including ligaments, cartilage, and menisci, enabling a detailed assessment of internal knee conditions.
Treatment Protocols: Treatment options focus on alleviating symptoms and restoring knee stability. They may include:
