Understanding the BASK Meniscal Surgery Guidelines (2018): Key Insights for Clinicians

The 2018 Meniscal Surgery Guidelines by the British Association for Surgery of the Knee (BASK) provide a comprehensive roadmap for assessing and managing meniscal injuries. Whether you’re a seasoned clinician or early in your career, these guidelines emphasize evidence-based practice, patient-centered care, and the importance of non-operative approaches where appropriate. Here’s a breakdown of the key points.

1. Identifying Symptoms and Treatment Pathways

Meniscal injuries can present with varying symptoms, categorized as:

• Strongly Suggestive (Meniscal): Locked knee, catching, or palpable tender meniscal tissue.
• Possibly Meniscal: Episodic sharp pain, intermittent swelling, or specific provocative signs like joint line tenderness or clicking.
• Arthritic: Crepitus, bony enlargement, or stiffness after inactivity, suggesting osteoarthritis (OA).

Key takeaway: Symptom duration matters. Acute injuries (<3 months) or chronic symptoms (>3 months) guide treatment pathways.

2. Non-Operative First: The Guiding Principle

Optimal non-operative treatment—including physiotherapy, exercise, analgesia, or injections—is often the first line of care, particularly for non-urgent cases. Surgery is considered only if these measures fail to improve symptoms.

---

3. When is Surgery Appropriate?

Surgical interventions are categorized based on clinical presentations:

• Urgent Arthroscopic Surgery: Indicated for cases like a locked knee caused by a bucket-handle tear.
• Arthroscopic Meniscal Repair: Recommended for suitable candidates with repairable meniscal tears.
• No Surgery: Advanced OA or minimal meniscal abnormalities on imaging typically warrant conservative care.

Imaging Role: MRI is key for detailed assessment unless clinical findings (e.g., locked knee) clearly indicate surgery.

4. Classifying Meniscal Tears: Treatable vs. Non-Treatable

The guidelines classify meniscal tears into treatable (e.g., displaced tears, bucket-handle tears) and non-treatable (e.g., minor contour abnormalities or isolated extrusion). This distinction ensures targeted interventions.

5. Case-Based Recommendations in Practice

The BASK guidelines offer detailed case examples to illustrate how clinical presentations, imaging findings, and symptom duration guide treatment decisions. Here’s a closer look at three scenarios:

• Example 1:
  • Presentation: A patient presents with a locked knee caused by a twisting injury one week prior.
  • Symptoms and Imaging: Examination and MRI confirm a bucket-handle meniscal tear, a treatable lesion that is causing a complete mechanical block to knee movement.
  • Recommendation: Urgent arthroscopic surgery is indicated to address the locked knee and restore mobility.
• Example 2:
  • Presentation: A patient with chronic knee pain and stiffness persisting for six months, with no history of acute injury.
  • Symptoms and Imaging: The clinical picture includes osteoarthritic symptoms such as aching pain and crepitus. Imaging reveals advanced structural OA alongside a possible meniscal tear.
  • Recommendation: Surgical intervention is not appropriate. The focus should be on non-operative management such as physiotherapy, exercise, and analgesia to manage symptoms and maintain function.
• Example 3:
  • Presentation: A twisting injury occurred one week ago, leading to pain and limited knee movement.
  • Symptoms and Imaging: MRI confirms a longitudinal meniscal tear located in the repairable zone of the meniscus.
  • Recommendation: Arthroscopic meniscal repair is advised if the patient is a suitable candidate, with the aim of preserving meniscal function.

These cases highlight the nuanced approach required in managing meniscal injuries, demonstrating how patient-specific factors and imaging results drive clinical decisions. By tailoring treatments to individual needs, clinicians can ensure the best possible outcomes.

6. The Role of Imaging

The use of imaging, particularly MRI, plays a pivotal role in diagnosis. For suspected OA, weight-bearing X-rays are the first step. When OA is ruled out, MRI is the preferred tool to confirm meniscal pathology.

---

7. Integrating Patient-Centered Care

Ultimately, the guidelines emphasize a personalized approach—balancing clinical findings, imaging results, and patient preferences. Non-surgical options remain foundational, reserving surgery for specific indications backed by evidence.

Why These Guidelines Matter

BASK’s Meniscal Surgery Guidelines serve as a critical tool for clinicians, ensuring care aligns with the latest evidence. They advocate for thoughtful decision-making, prioritizing non-operative management while recognizing when surgery is necessary.

For clinicians, these guidelines provide clarity. For patients, they promise care that’s both effective and empathetic—a balanced approach to managing complex knee conditions.
