M22.10
Recurrent subluxation of patella, unspecified knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Recurrent subluxation of the patella refers to repeated episodes where the kneecap (patella) partially slips out of its normal position. This condition can cause instability, pain, and can affect daily activities and mobility. It most often involves the knee joint and is classified under ICD-10 code M22.10. Recognizing the symptoms and understanding potential causes can help in seeking appropriate management for this condition.
Causes & Symptoms
Clinical Causes: Weakness or imbalance in the thigh muscles, especially the quadriceps Anatomical abnormalities such as a shallow trochlear groove or high-riding patella Injury or trauma that damages the stabilizing structures of the knee Ligamentous laxity or hypermobility syndromes Recurrent sports injuries or activities involving frequent twisting or squatting
Key Symptoms: Repeat episodes of the kneecap slipping out of its normal position Pain around the front of the knee, especially after dislocation events Swelling or inflammation around the knee joint A sense of instability or the knee feeling like it is 'giving way' Crepitus or grinding sensations during knee movement Tenderness along the edges of the kneecap
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a physical examination to assess knee stability and alignment, along with medical history review. Imaging studies, such as X-rays, MRI scans, or CT scans, help to identify anatomical factors and extent of soft tissue damage. Special tests may be performed to evaluate the tendency of the kneecap to slip out of place and identify structural abnormalities.
Treatment Protocols: Physical therapy focused on strengthening the quadriceps and other supporting muscles around the knee Use of knee braces or taping techniques to provide additional stability during activities Activity modifications to avoid movements that trigger dislocation Pain management with medications if necessary In severe or persistent cases, surgical interventions may be considered, such as realignment procedures or repair of torn tissues
