Conditions We Treat

Dr. Kahn has extensive personal and professional experience in the evaluation and non-surgical management of knee pain, after sustaining numerous athletic and non-athletic related knee injuries himself, and undergoing multiple surgical and non-surgical treatments, including arthroscopy, artificial join fluid (viscosupplementation) injections, therapeutic bracing, and rehabilitation. His approach to knee pain includes both a biomechanical and radiological analysis, and he is often able to determine that the pain is secondary to another joint disorder, such as at the level of the pelvis, hip, or foot, or due to muscle imbalances after an injury or due to activity-specific causes. Our practices treats a variety of knee related disorders from adolescents to seniors, including:

  • Patellar tendonitis and quadriceps tendonitis
  • Pre-patellar and infrapatellar bursitis
  • Sprains and strains of cruciate and collateral ligaments
  • Synovitis and inflammatory disorders of the knee
  • Osteoarthritis of the medial, lateral, and patellofemoral compartments
  • Non-surgical treatment of tears of the meniscus and cruciate ligaments

Diagnostic Tests

Standard x-ray imaging of the knee, including AP and lateral views, has limited diagnostic value except when attempting to exclude fracture, tumor, or infection, and even in those cases may miss important pathology. When indicated, we obtain x-rays with the patient standing, and include Merchant’s view to analyze the patellofemoral compartment. MRI scan of the knee is an excellent overall diagnostic tool which demonstrates pathology of bone, articular cartilage, muscle, ligament, and meniscus. The usage of CT scan and nuclear bone scan may play a role in evaluating suspected bone lesions, tumor, infection, or prosthetic loosening. All of these procedures are available either at Brittonfield Medical Center or at the imaging center across the street from our office.

Within our own office suite, we offer non-invasive and non-radiating diagnostic testing, which requires no insurance pre-authorization:

  • Diagnostic musculoskeletal ultrasound (US-MSK) is an excellent diagnostic tool in the evaluation of knee disorders, as it clearly demonstrates the presence of joint effusion (swelling), bursitis, tendinopathy, changes in articular (chondral) cartilage, and can identify various types of meniscal disorders


  • Joint aspiration (drainage of fluid) and injection with corticosteroid agents
  • Injection of various tendon and bursa related structures and disorders
  • Injection of artificial joint fluid (viscosupplementation) for the treatment of osteoarthritis
  • Custom and off the shelf orthotics (knee braces)
