5D Lipo Laser for the Knees: Inner Knee Fat Reduction Protocol

June 25 2026, by Kashif Amin, 11 min reading time

Inner knee fat is one of the most overlooked yet most impactful body contouring areas in aesthetic practice. This guide covers the complete 5D Lipo Laser protocol for inner knee fat reduction: client assessment, pad placement, session structure, RF skin tightening, realistic results, and aftercare.

Inner knee fat — the soft, rounded fat deposit that accumulates on the medial aspect of the knee, just above and around the knee joint — is one of the most overlooked yet most impactful body contouring areas in aesthetic practice. It affects both male and female clients, is notoriously resistant to diet and exercise, and has a significant impact on how the legs look in profile and how fitted clothing sits across the knee and lower thigh.

5D Lipo Laser is well-suited to inner knee fat reduction. The medial knee fat deposit is predominantly subcutaneous, soft, and accessible to laser stimulation, and the combination of lipo laser fat reduction and RF skin tightening delivers a meaningful improvement in knee contour and the overall leg silhouette. This guide covers everything a practitioner needs to know about treating the inner knee with 5D Lipo Laser.

1. Understanding Inner Knee Fat

Inner knee fat accumulates on the medial aspect of the knee — the area on the inside of the knee joint, extending from the lower inner thigh to the upper inner calf. It is driven by a combination of genetics, hormonal fat distribution, and the natural tendency for fat to accumulate around joints as part of the body’s protective padding mechanism.

The inner knee fat deposit is characterised by a relatively small volume compared to other lower body fat deposits, but its location — directly at the knee joint — makes it disproportionately visible and impactful on the overall leg silhouette. Even a modest reduction in the inner knee fat deposit can create a meaningful improvement in the appearance of the knee and the overall leg line.

2. Client Assessment for Knee Treatment

The assessment for inner knee treatment follows the standard consultation protocol, with specific attention to the extent and depth of the medial knee fat deposit and the client’s goals for their knee and leg silhouette.

Ask the client to stand with their feet together and assess the inner knee from the front and side. Note the extent of the fat deposit — whether it is confined to the medial knee or extends up the inner thigh or down the inner calf — and the degree to which it disrupts the overall leg line. Perform the pinch test at the point of maximum fat depth on the medial knee — a pinch depth of 1.5 centimetres or more indicates a sufficient volume of subcutaneous fat that will respond to lipo laser treatment.

The inner knee is a smaller treatment area than most other body contouring zones, and the fat volume is typically lower. Set realistic expectations at the consultation — the result for inner knee clients is a refined and more defined knee contour rather than a dramatic circumference reduction. Take baseline circumference measurements at the knee level and photograph the treatment area from the front and side with the client standing with feet together.

3. Pad Placement for the Inner Knee

Pad placement for inner knee treatment requires careful positioning to ensure the paddles are in full contact with the medial knee fat deposit.

Position the client lying on their back (supine) with the knees slightly bent and supported by a rolled towel or bolster beneath the knees. This position relaxes the medial knee tissue and allows the paddles to be positioned flat against the inner knee fat deposit.

For standard inner knee treatment, position 4 to 6 paddles across the medial knee surface, covering the fat deposit from the lower inner thigh to the upper inner calf. The paddles should be arranged in a vertical column following the medial knee contour. Secure the paddles with the provided straps or wraps to maintain contact during the session. Treat both knees in the same session by repositioning the paddles from one knee to the other after the first side is complete.

4. Session Duration and Machine Settings

The standard session duration for inner knee treatment is 15 to 20 minutes per knee, or 30 to 40 minutes for bilateral treatment in the same session.

Use the continuous operation mode for inner knee treatment to maintain consistent laser energy delivery throughout the session. The five wavelengths of the 5D Lipo Laser — 650nm, 780nm, 808nm, 940nm, and 980nm — work simultaneously to stimulate fat cells across the full depth of the medial knee subcutaneous layer. The inner knee fat is typically soft and responsive, and the laser energy penetrates effectively from the first session.

5. RF Skin Tightening for the Knee Area

RF skin tightening is a particularly valuable addition to the inner knee protocol. The skin around the knee joint is prone to laxity, particularly in older clients and clients who have lost significant weight, and the combination of fat reduction and skin tightening delivers a significantly better result than fat reduction alone.

Apply the RF treatment to the medial knee and lower inner thigh immediately after the lipo laser session, while the tissue is warm and the lymphatic system is active. A 10 to 15 minute RF treatment delivers a meaningful collagen stimulation benefit that firms the skin and improves the overall texture of the knee area.

6. Combining Knee Treatment with Other Areas

Inner knee treatment is most commonly combined with inner thigh treatment as part of a comprehensive medial lower body contouring course. The inner knee fat deposit is anatomically continuous with the inner thigh fat deposit, and treating both areas in the same course delivers a complete medial leg reshaping result that improves the overall inner leg silhouette from the upper thigh to the knee.

Inner knee treatment is also commonly combined with outer thigh and banana roll treatment for clients who want to address the full lower body silhouette from all angles.

7. Session Protocol and Course Structure

The recommended course structure for inner knee treatment is 8 to 10 sessions, delivered once or twice per week. The inner knee is a smaller treatment area than most other body contouring zones, and an 8-session course is often sufficient to achieve a meaningful result for clients with a modest inner knee fat deposit. Clients combining knee treatment with inner thigh treatment may benefit from a 10 to 12 session course.

Take circumference measurements at the knee level at every session and record the data in the client’s file. Photograph the treatment area from the front and side at the baseline, midpoint, and end of course.

8. What Results Are Realistic for Knee Contouring Clients?

A realistic expectation for most clients completing a standard 8 to 10 session inner knee course is a visible reduction in the medial knee fat deposit, a more defined and refined knee contour, a circumference reduction of 1 to 3 centimetres at the knee level, and a meaningful improvement in the overall inner leg silhouette.

The inner knee result is particularly impactful for clients who are self-conscious about the appearance of their knees in skirts, shorts, or swimwear. Many clients report that the improvement in their knee contour has a significant positive impact on their confidence in clothing that exposes the knee area.

9. Aftercare for Inner Knee Treatment Clients

The aftercare protocol for inner knee treatment clients follows the standard aftercare guide. Walking for at least 20 to 30 minutes within two hours of each session is the primary aftercare recommendation, as walking activates the lymphatic pump in the lower limbs and accelerates the elimination of the fatty acids released during the session.

Advise inner knee treatment clients to avoid wearing tight knee-high socks, compression stockings, or tight leggings that compress the knee area in the 24 hours after each session. Loose, comfortable clothing is recommended for the remainder of the treatment day.

Encourage inner knee treatment clients to perform gentle knee flexion and extension exercises and calf raises in the 24 hours after each session to stimulate the lymphatic vessels in the treatment area.
