MRI Patellar Tracking

Partially — MRI can detect structural causes and consequences of patellar tracking disorder, such as trochlear dysplasia, patellar tilt or lateral translation, patellar height abnormalities, MPFL tears, cartilage damage, and bone bruises. However, routine static MRI may miss dynamic maltracking that occurs during movement; weight-bearing/kinematic imaging or dynamic studies plus clinical assessment are often needed to confirm functional maltracking and guide treatment.

Patellar tracking describes how the kneecap (patella) glides within the femoral groove during knee bending and straightening. Normal tracking keeps the patella centered; maltracking involves sideways shift, tilt or instability, causing pain, grinding, swelling and cartilage wear. Causes include muscle imbalance, poor alignment, injury or ligament laxity. Diagnosis uses exam and imaging; treatment focuses on physiotherapy, strengthening, taping, orthotics, and rarely surgery.

The patellar tracking test assesses patella motion during active knee flexion and extension. The clinician observes for lateral deviation or a J-sign, checks medial and lateral patellar glide and patellar apprehension, and may perform a patellar grind (Clarke) test. Positive findings—lateral tracking, tilt, crepitus, pain, or apprehension—suggest patellar maltracking or instability; Q-angle and imaging are adjuncts.

Treat patellar tracking by modifying activities and using ice/NSAIDs for pain control, plus physiotherapy to strengthen the quadriceps (especially VMO) and hip abductors/glutes, and stretch the IT band and hamstrings. Use patellar taping or a supportive brace and consider orthotics for foot mechanics. Maintain weight control. If pain, swelling, or locking persists despite rehab, consult an orthopedic specialist.

You may run with patellar tracking disorder if pain is controlled, but only with modifications and rehabilitation. Begin pain-free, reduce speed/volume, avoid hills/steps, and use a gradual return. Key measures: quadriceps (VMO) and hip-abductor strengthening, stretching tight structures, gait/footwear assessment, patellar taping or brace for symptom relief, and cross‑training. See a physiotherapist or clinician if pain or instability persists.

Yes. MRI is excellent at detecting many knee problems, including ligament tears (ACL, PCL, MCL, LCL), meniscal tears, cartilage defects, bone bruises or occult fractures, joint inflammation, synovitis, tumors, and degenerative changes. It visualizes soft tissues and bone marrow better than X‑ray. Results should be interpreted with clinical examination and sometimes additional imaging for alignment or surgical planning.
