What is the treatment for a longitudinal horizontal tear of the body and posterior horn of the medial meniscus with distal quadriceps tendinosis?

Treatment for Longitudinal Horizontal Tear of Medial Meniscus with Distal Quadriceps Tendinosis

Conservative management is strongly recommended as the first-line treatment for a longitudinal horizontal tear of the body and posterior horn of the medial meniscus with distal quadriceps tendinosis, as arthroscopic surgery offers no significant benefit over non-surgical approaches for degenerative meniscal tears. 1

Conservative Management Approach

Physical Therapy and Exercise

• A structured physical therapy program should be implemented as the cornerstone of treatment, focusing on strengthening exercises for the quadriceps and hamstrings 2
• Eccentric exercises are particularly beneficial for quadriceps tendinosis and should be incorporated into the rehabilitation protocol 1
• Tensile loading of the tendon stimulates collagen production and guides normal alignment of newly formed collagen fibers, which is essential for healing 1
• Complete immobilization should be avoided to prevent muscular atrophy and deconditioning 1

Pain Management

• NSAIDs (oral or topical) are effective for pain relief in both the meniscal tear and quadriceps tendinosis 1
• Topical NSAIDs may be preferred to avoid gastrointestinal side effects associated with oral NSAIDs 1
• Cryotherapy (ice) should be applied through a wet towel for 10-minute periods to reduce pain and swelling 1

Intra-articular Injections

• Corticosteroid/bupivacaine injections may provide significant symptom relief in patients with degenerative tears of the posterior horn of the medial meniscus 3
• Up to 82% of patients report improvement following guided intra-articular knee steroid/bupivacaine injection, with complete resolution in 42% of cases 3
• Patients with isolated tears (without significant osteoarthritis) are more likely to have favorable outcomes with injections 3

When to Consider Surgery

Surgery should only be considered in specific circumstances:

• After failure of a comprehensive conservative treatment program lasting at least 3 months 2, 4
• In cases of persistent objective locked knee (true mechanical locking) 1
• For younger patients with acute traumatic tears rather than degenerative tears 2, 5

Expected Outcomes

Conservative Management

• Most patients experience decreased pain severity and frequency within 3 months of starting conservative treatment 4
• Clinical outcomes typically improve at 12 months follow-up, though may decline somewhat after that while still remaining improved over baseline 4
• Non-operative treatment of medial meniscus posterior horn root tears has shown poor long-term outcomes in some studies, with 87% of patients showing failure at 5-year follow-up 6

Surgical Management

• If surgery becomes necessary, the recovery typically takes 2-6 weeks 1
• At least 1-2 weeks off work is usually required, depending on job demands 1
• While meniscal repair has higher reoperation rates compared to partial meniscectomy, long-term outcomes show better clinical results and less severe degenerative changes 5

Common Pitfalls to Avoid

• Rushing to surgery without an adequate trial of conservative management 2
• Assuming all mechanical symptoms require surgical intervention 2
• Overlooking the quadriceps tendinosis component, which requires specific eccentric strengthening exercises 1
• Failing to recognize that MRI often shows false-negative results for radial tears of the posterior horn of the medial meniscus 7

Monitoring and Follow-up

• Regular assessment of pain levels and functional improvement using standardized scales (Visual Analog Scale, Lysholm Knee Scoring scale) 4
• Radiographic monitoring for progression of osteoarthritis, particularly in patients over 50 years 6
• Adjustment of the conservative management program based on patient response and progress 2, 4
