Conservative Management of Chondromalacia Patellae

Introduction to Conservative Management

A comprehensive conservative management approach is recommended, including quadriceps strengthening, medial patellar taping, weight management, and topical NSAIDs for pain control, as suggested by the American Academy of Orthopaedic Surgeons 1
Aquatic exercises may be beneficial for patients who are aerobically deconditioned, as part of a comprehensive conservative management approach 2
Weight loss is strongly recommended for overweight patients, and should include a structured approach with regular self-monitoring and increased physical activity 2, 3
A structured approach to weight loss should include regular self-monitoring, support meetings, increased physical activity, structured meal planning, and reduced fat, sugar, and salt intake, as suggested by the Annals of the Rheumatic Diseases 3

Topical NSAIDs are strongly recommended as first-line treatment due to lower systemic absorption, fewer adverse effects, and particular benefits for patients ≥75 years or with GI risk factors, as suggested by the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
Oral NSAIDs are strongly recommended as second-line treatment when topical treatments are insufficient, with consideration for gastric protection, according to the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
Paracetamol (up to 4g/day) is recommended for mild to moderate pain, and weak opioids can be used for moderate to severe pain when other options have failed, with caution due to risk of dependence, as recommended by the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
Acetaminophen may be used for mild to moderate pain, up to 4g/day, as part of a conservative management approach 2

Medial patellar taping provides short-term relief of pain and improved function, and is more effective when compared to no taping 1
Patellofemoral bracing is conditionally recommended, and a brace with valgus-directing force may be considered for medial compartment involvement 1
Tibiofemoral bracing is strongly recommended for tibiofemoral OA, and patellofemoral bracing is conditionally recommended for patellofemoral OA, according to the Arthritis care & research journal 5

Quadriceps strengthening exercises, particularly closed kinetic chain exercises like semi-squats, are superior to open kinetic chain exercises like straight leg raises 2
Closed kinetic chain exercises like semi-squats are more effective than open kinetic chain exercises for reducing Q angle, decreasing crepitation, increasing quadriceps strength, and increasing thigh circumference 2
Exercise should include walking, strengthening exercises, neuromuscular training, and aquatic exercise, as recommended by the Arthritis care & research journal 5
Quadriceps strengthening exercises are strongly recommended as they provide statistically significant and clinically important effects on pain and function, according to the American Academy of Orthopaedic Surgeons 1

A stepped-care approach can be used, with first-line treatment including exercise therapy, weight management, appropriate footwear, and topical NSAIDs, according to the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
Second-line treatment can include oral NSAIDs, bracing, and intra-articular glucocorticoid injections, and third-line treatment can include re-evaluation of diagnosis and treatment adherence, consideration of referral to an orthopedic specialist, and evaluation for surgical intervention if conservative measures fail, as suggested by the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
The initial 6-8 weeks of treatment should focus on daily quadriceps strengthening, medial patellar taping, weight management, and topical NSAIDs for pain control 2
If there is an inadequate response after 8 weeks, oral NSAIDs and patellofemoral bracing may be considered, and physical therapy should be intensified 1

Lateral heel wedges should not be used for medial compartment OA, as they are not recommended 1
Quadriceps strengthening should not be neglected, as it is the cornerstone of conservative management 1
Surgical intervention should not be rushed into before an adequate trial of conservative management, which should last at least 3-6 months 1
Total knee arthroplasty (TKA) should be considered when the patient has failed conservative management, has progressive pain and functional limitation, and radiographic evidence shows moderate to severe degenerative changes, according to the American Academy of Orthopaedic Surgeons 6
Before surgery, patients should enroll in weight loss programs if overweight, participate in structured physical therapy to strengthen quadriceps, and achieve good control of any comorbidities, as recommended by the American Academy of Orthopaedic Surgeons 6

Regular assessment of pain control and function, monitoring for medication side effects, and adjusting the treatment plan based on disease progression and response to therapy are essential, according to the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
Consider specialist referral if there is established functional limitation and severe refractory pain despite conservative management, as recommended by the Praxis Medical Insights: Practical Summaries of Clinical Guidelines 4
