The product injected matters, but so does how and where it is placed. An injection that reaches the intended space delivers its full effect, while one placed outside the joint may provide little benefit and more discomfort. This article reviews the main orthopedic injection techniques and the factors that improve accuracy and results.<\/p>\n\n\n\n

Understanding Orthopedic Injection Techniques<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

An injection technique combines the choice of approach (the entry point and needle path), the patient’s position, the needle size and the use or not of imaging guidance. Clinicians choose the technique according to the joint, the patient’s anatomy, the product and the goal of treatment. In Canada, who may perform intra-articular injections varies by province and professional college.<\/p>\n\n\n\n

The Role of Precision and Anatomy<\/h2>\n\n\n\n

Viscosupplements such as SYNVISC\u00ae<\/a>, MONOVISC\u00ae<\/a>, DUROLANE\u00ae<\/a> and ORTHOVISC\u00ae<\/a>, as well as combination products such as CINGAL\u00ae<\/a>, are designed to be placed inside the joint space. A good knowledge of anatomy, careful palpation of landmarks and, when needed, imaging guidance all help the needle reach the right place. When a joint effusion is present, aspirating excess fluid before the injection can also improve comfort and product distribution.<\/p>\n\n\n\n

Common Techniques for Orthopedic Injection<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

1. Superolateral and Anterolateral Approaches (Knee)<\/h3>\n\n\n\n

For the knee, the superolateral approach, with the leg extended, enters the joint above and to the outside of the kneecap. It is often preferred when an effusion is present. The anterolateral approach, with the knee bent, enters beside the patellar tendon and is common when the patient is seated.<\/p>\n\n\n\n

2. Anteromedial Approach (Knee)<\/h3>\n\n\n\n

The anteromedial approach enters on the inner side of the patellar tendon with the knee bent. It can be useful depending on the patient’s anatomy or the clinician’s preference.<\/p>\n\n\n\n

3. Posterior and Anterior Approaches (Shoulder)<\/h3>\n\n\n\n

For the glenohumeral joint, the posterior approach is frequently used, entering below the back of the acromion and aiming toward the front. The anterior approach is an alternative. The subacromial space is targeted for certain rotator cuff conditions.<\/p>\n\n\n\n

4. Infiltration Techniques for Soft Tissue<\/h3>\n\n\n\n

Some conditions affect tendons, bursae or ligaments rather than the joint itself. Infiltration places the product around these structures, for example in a bursa of the shoulder or hip, while avoiding injection directly into a tendon.<\/p>\n\n\n\n

5. Ultrasound-Guided Injections<\/h3>\n\n\n\n

Ultrasound shows the needle and the target in real time. It improves accuracy, particularly for deep joints such as the hip, for small joints and for patients whose landmarks are difficult to palpate. Many Canadian clinics now use it routinely for viscosupplementation.<\/p>\n\n\n\n
