Knee Taping: Techniques, Benefits, and Applications for Support and Pain Relief

How to tap a knee?

When discussing "tapping" a knee in a fitness or rehabilitation context, the most common and beneficial interpretation refers to the application of athletic tape to provide support, reduce pain, or enhance proprioception for various knee conditions and activities.

Understanding "Tapping" the Knee: Clarifying the Intent

The phrase "tapping a knee" can carry a few different meanings depending on the context. In a medical diagnostic setting, it might refer to eliciting the patellar reflex with a reflex hammer. In general exercise, it could simply mean lightly touching the knee, perhaps as part of a warm-up or coordination drill. However, within the realm of exercise science, sports medicine, and rehabilitation, "tapping the knee" is almost universally understood as applying athletic tape to the knee joint. This comprehensive guide will focus on the principles and techniques for knee taping, a valuable tool for athletes, fitness enthusiasts, and individuals managing knee discomfort.

Why Tape the Knee? Benefits and Applications

Knee taping is a non-invasive strategy employed for a variety of purposes related to knee health and performance. Its benefits stem from providing external support and influencing proprioceptive feedback.

• Support and Stability: Taping can provide mechanical support to unstable knee joints, helping to restrict excessive or painful movements, particularly following ligamentous sprains or during recovery from certain injuries.
• Pain Reduction: By offloading stressed tissues, compressing swollen areas, or subtly altering movement patterns, taping can significantly reduce pain during activity or rest.
• Injury Prevention: For athletes participating in high-impact or pivoting sports, taping can offer an added layer of support, potentially reducing the risk of re-injury or initial injury to vulnerable structures.
• Swelling Management: Kinesiology tape, in particular, can be applied to lift the skin, creating space for improved lymphatic drainage and reducing localized swelling.
• Proprioceptive Feedback: The sensation of the tape on the skin provides continuous sensory input to the nervous system, enhancing body awareness and encouraging more controlled movement patterns. This can be crucial for motor control retraining.

Types of Athletic Tape for Knee Applications

Selecting the correct type of tape is crucial for achieving the desired outcome.

• Rigid (Athletic) Tape:
  • Characteristics: Non-stretch, strong adhesive, typically white or colored cotton-based.
  • Purpose: Provides robust mechanical support and limits range of motion. Ideal for acute injury support, restricting unwanted joint movement, or offloading specific structures.
  • Common Use: Patellar stabilization (McConnell taping), collateral ligament support.
• Kinesiology (K-Tape) Tape:
  • Characteristics: Elastic, breathable, water-resistant, similar stretch properties to human skin.
  • Purpose: Designed to provide proprioceptive feedback, facilitate or inhibit muscle activity, reduce swelling, and alleviate pain without significantly restricting movement.
  • Common Use: General knee pain, patellofemoral pain syndrome, muscle imbalances, swelling reduction.

Essential Principles Before Taping

Proper preparation is key to effective and safe taping.

• Clean, Dry Skin: Ensure the skin is free of oils, lotions, and sweat to maximize tape adhesion.
• Hair Removal: For optimal adhesion and to prevent painful removal, consider shaving or trimming hair in the taping area.
• Skin Protection: For sensitive skin or if using rigid tape, applying a pre-wrap (underwrap) can protect the skin from irritation and blistering. Adhesive sprays can also be used to enhance tape grip.
• Correct Joint Position: The knee must be positioned correctly (e.g., slightly bent, fully extended) according to the specific taping technique to ensure effectiveness and avoid constricting movement or circulation once the tape is applied.
• Avoid Over-Tightening: Never apply tape so tightly that it causes numbness, tingling, discoloration, or increased pain. Always check circulation (capillary refill) after application.
• Professional Guidance: For significant injuries or chronic pain, always consult with a qualified healthcare professional (e.g., physical therapist, athletic trainer, orthopedic doctor) before attempting self-taping. They can diagnose the issue, recommend the appropriate technique, and teach you proper application.

Common Knee Taping Techniques

Here are detailed steps for some common knee taping applications using both rigid and kinesiology tape.

For Patellar Tracking Issues (McConnell Taping / Patellar Stability)

This technique uses rigid tape to correct patellar alignment and reduce pain, commonly for patellofemoral pain syndrome.

• Purpose: To medialize (pull inwards), tilt, or rotate the patella to improve tracking and reduce stress on the joint.
• Materials: Rigid athletic tape (e.g., 1.5-inch), pre-wrap (optional).
• Steps:
  • Patient Position: Lie on your back with the knee slightly bent (approx. 20-30 degrees) and relaxed.
  • Skin Prep: Clean and dry the skin around the patella. Apply pre-wrap if desired.
  • Anchor Strips: Apply two horizontal anchor strips of pre-wrap or light adhesive tape. One above the patella, one below, extending slightly wider than the patella.
  • Correction Strip (Medial Glide): From the outer edge of the patella, pull the patella medially (towards the inner thigh) and apply a rigid tape strip that adheres to the inner anchor strip. Apply this strip with significant tension to pull the patella.
  • Correction Strip (Tilt/Rotation - if needed): Depending on the specific patellar malalignment, additional strips can be applied to correct tilt or rotation. For example, to correct an inferior tilt, a strip might pull the lower border of the patella upwards.
  • Locking Strips: Apply additional horizontal strips over the anchor strips to secure the corrective strips, ensuring they don't peel off.

For Ligamentous Support (MCL/LCL)

This technique provides external support to the medial collateral ligament (MCL) or lateral collateral ligament (LCL) following a sprain or for preventative measures.

• Purpose: To limit valgus (knock-kneed) or varus (bow-legged) stress on the knee joint.
• Materials: Rigid athletic tape (e.g., 1.5-2 inches), pre-wrap (optional).
• Steps (for MCL support - valgus stress):
  • Patient Position: Standing or sitting with the knee slightly flexed (about 15-20 degrees).
  • Skin Prep: Clean and dry the skin. Apply pre-wrap around the mid-thigh and mid-calf.
  • Anchor Strips: Apply one anchor strip circumferentially around the mid-thigh (just above the knee joint) and another around the mid-calf (just below the knee joint).
  • Support Strips (Medial Side): Starting from the outer aspect of the thigh anchor, bring a strip diagonally across the medial side of the knee (where the MCL is located) and attach it to the inner aspect of the calf anchor. Apply 2-4 such strips, overlapping slightly, to create a strong medial support. You can also apply an 'X' pattern across the joint for enhanced support.
  • Locking Strips: Apply additional circumferential strips over the thigh and calf anchors to secure the support strips.

For General Knee Pain / Swelling (Kinesiology Taping)

Kinesiology tape can be used for various purposes, from pain relief to reducing swelling.

• Purpose: To alleviate general knee pain, reduce swelling, or provide gentle support without restricting movement.
• Materials: Kinesiology tape (e.g., 2-inch wide).
• Steps (Example: Pain around Patella):
  • Patient Position: Knee slightly bent (approx. 20-30 degrees).
  • Skin Prep: Clean and dry skin.
  • "I" Strip Application (for pain/support):
    • Measure an "I" strip long enough to go from below the patella, around one side, and above the patella.
    • Tear the backing in the middle. With the knee bent, apply the middle of the strip with 0% stretch just below the patella (the base).
    • Gently pull one end of the tape around the side of the patella (e.g., medially) with 25-50% stretch, adhering it above the patella.
    • Repeat with another "I" strip from the other side, creating a "basket" or "X" pattern over the patella. Rub to activate adhesive.
  • "Fan" Strip Application (for swelling):
    • Cut one long "I" strip and cut it into 4-5 narrow "fingers" at one end, leaving an uncut base.
    • Anchor the uncut base of the tape below or above the swollen area with 0% stretch.
    • Fan out the individual "fingers" over the swollen area, applying them with very light (0-15%) stretch, creating a ripple effect. This lifts the skin to promote lymphatic drainage. Rub to activate adhesive.

Post-Taping Care and Considerations

Once the tape is applied, ongoing vigilance is important.

• Monitor Skin: Regularly check the skin beneath and around the tape for any signs of irritation, redness, itching, blistering, numbness, or increased pain. If any of these occur, remove the tape immediately.
• Duration of Wear: Rigid tape is typically worn for short periods (hours to a day) during activity. Kinesiology tape can be worn for 3-5 days, even through showering, as long as it remains comfortable and effective.
• Tape Removal: Remove tape slowly and carefully to avoid skin damage. It's often easier to remove in the shower or by saturating it with oil to loosen the adhesive. Pull the tape back on itself, pulling parallel to the skin, rather than pulling straight up.
• When to Seek Professional Help: Taping is a supportive measure, not a cure. If pain persists, worsens, or new symptoms develop, discontinue taping and consult a healthcare professional for a thorough evaluation.
