Understanding Chondromalacia Patella (Runner's Knee)? This guide provides clinicians with information on Chondromalacia Knee diagnosis, including Patellofemoral Pain Syndrome symptoms, ICD-10 coding for Chondromalacia, and best practices for clinical documentation of Runner's Knee. Learn about effective treatment options and healthcare strategies for managing Chondromalacia.
Also known as
Internal derangements of knee
Includes chondromalacia and other knee cartilage disorders.
Other specified diseases of cartilage
May include chondromalacia not otherwise specified.
Other specified soft tissue disorders
Can be used for patellofemoral pain syndrome if not classified elsewhere.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the chondromalacia patellar?
Yes
Is it bilateral?
No
Is the chondromalacia of another site in the knee?
When to use each related code

| Softening of knee cartilage |
| Irritation of the patellar tendon |
| Inflammation of the iliotibial band |
Coding chondromalacia requires specifying right, left, or bilateral. Unspecified laterality leads to claim denials and inaccurate data.
Coding to patellofemoral pain syndrome (Runner's Knee) when documented as chondromalacia lacks specificity and can trigger audits.
Lack of clinical evidence supporting chondromalacia diagnosis can lead to coding errors and compliance issues during audits.
Q: What are the best evidence-based conservative treatment options for chondromalacia patellae in young athletes?
A: Conservative management is the first-line treatment for chondromalacia patellae, particularly in young athletes. Evidence-based interventions include activity modification to avoid exacerbating activities like deep squats and stair climbing, physical therapy focusing on strengthening the quadriceps and hip abductors, improving patellar tracking, and addressing any biomechanical deficiencies. Furthermore, consider implementing pain management strategies like NSAIDs, ice, and patellar taping or bracing. Explore how biomechanical analysis can identify underlying movement patterns contributing to patellofemoral pain syndrome. In cases of persistent pain despite conservative measures, explore diagnostic imaging such as MRI to rule out other pathologies.

Q: How can I differentiate chondromalacia patellae from other causes of anterior knee pain like patellar tendinopathy or osteoarthritis in my differential diagnosis?
A: Differentiating chondromalacia patellae, also known as runner's knee, from other anterior knee pain conditions requires a thorough clinical evaluation. Chondromalacia is characterized by retropatellar pain worsened by activities like running, squatting, or prolonged sitting. Unlike patellar tendinopathy, which typically presents with localized tenderness at the patellar tendon, chondromalacia pain is more diffuse around the patella. Furthermore, osteoarthritis typically affects older patients and presents with crepitus and morning stiffness, whereas chondromalacia is more common in younger, active individuals. Consider implementing a physical exam that includes assessing patellar mobility, tracking, and the presence of pain with the patellar grind test. Imaging studies like X-rays can help rule out osteoarthritis, while MRI can be useful in evaluating cartilage damage in advanced cases of chondromalacia. Explore how advanced imaging techniques can aid in differential diagnosis of knee pain.
Patient presents with complaints consistent with chondromalacia patellae, also known as patellofemoral pain syndrome or runner's knee. The patient reports anterior knee pain, characterized as a dull ache or sharp pain around or behind the patella. Symptoms are exacerbated by activities such as running, jumping, squatting, stair climbing, and prolonged sitting with knees bent. The patient denies any specific injury or trauma to the knee. Physical examination reveals tenderness on palpation of the patella and crepitus with range of motion. No effusion or instability noted. McMurray's test is negative. Differential diagnosis includes patellar tendinitis, prepatellar bursitis, and iliotibial band syndrome. Assessment: Chondromalacia patellae (ICD-10-CM: M22.42). Plan: Conservative management is recommended, including rest, ice, compression, elevation (RICE), and over-the-counter NSAIDs such as ibuprofen for pain management. Referral to physical therapy for strengthening and stretching exercises targeting the quadriceps, hamstrings, and hip abductors. Patient education provided regarding activity modification and proper body mechanics. Follow-up scheduled in four weeks to assess response to treatment. If symptoms persist or worsen, further evaluation with imaging studies such as an X-ray or MRI may be considered to rule out other pathologies.
