Knee Aspiration & Injection Trainer with Ultrasound Capabilities (Light Skin Tone)
An anatomically accurate adult knee model for injection and aspiration of synovial fluid from the knee joint, from both the lateral and medial aspects, using palpation or ultrasound guidance.
The robust sealed knee includes: knee joint, patella, patellar tendon and the suprapatellar space.
Discrete muscle, skin and fat layers, provide realistic tissue and needle response, while key anatomical landmarks are realistic to palpate. This enables trainees to improve their accuracy of injection and aspiration through repeatable practise.
Performing knee aspirations and injections are fundamental skills required for Internal Medical Trainees, as well as Rheumatologists, Doctors practising General Medicine and Orthopaedic Surgeons*
This model was evaluated by Charles Wakeley (Bristol Royal Infirmary, UK) and Andrew Grainger (Leeds Teaching Hospitals, UK).
The Synovial Fluid used with this product now contains a new preservative which is approved for use by EU cosmetic regulations which means that it is safe for extended skin contact.
We still recommend the use of gloves, as the pigments may stain skin and clothes.

Overview
- 1,000+ stabs per module with 21 gauge needle
- Precise, palpable anatomy with bony landmarks
- Robust, sealed knee unit that holds all anatomy
- Key internal landmarks visible under ultrasound
- Compatible with all standard ultrasound machines
- Echolucent material allows aspiration and injection under ultrasound guidance or using the palpation method
- Suitable for Undergraduate and Postgraduate medical study
- Knee skin is watertight
Realism
- Discrete muscle and skin layers provide realistic tissue and needle response
- Anatomically accurate synovial sac and palpable patella
- Realistic color and consistency of synovial fluid
Versatility
- Can be used with leg supports for supine position, or without leg supports for side of bed position
- Caters for ultrasound-guided techniques as well as palpation
- Separate Fluid Bag & Stand ensure the model is easy to use and mobile
- Clear indicator on Fluid Bag to prevent overfilling
Cleaning
- Clean off any residual ultrasound gel from the knee injection trainer
- Skin surface should be cleaned with a soft, damp cloth, using warm water and mild detergent
- Empty any remaining fluid from the knee once the procedure is complete
- Allow knee injection model to dry before storing
Safety
- This product is latex free
- If the model sustains damage, refer all servicing to qualified servicing personnel
- During practice injections, be sure to remove the needle at the same angle as inserted, removing at an angle can cause the knee skin to split
- We advise that you do not use simulator if the skin of the knee is torn
- Always store/dispose of needles safely in the sharps bin supplied or a suitable alternative
- While the new Synovial Fluid in this product contains a new preservative (approved for use by EU cosmetic regulations) meaning it is safe for extended skin contact, we still recommend the use of gloves while using this product
Simulated Patient
- This knee model can be used with a simulated patient to practice knee joint aspiration and injection
Anatomy

- Competence using ultrasound technology to perform
- systematic scanning techniques and examination of the knee joint
- Identification of anatomical landmarks using ultrasound guidance or the palpation method
- Patient positioning and management
- Recognition of joint effusion
- Ballottement

Can this knee aspiration and injection model be injected with fluid?
This knee model can be injected with fluids to aid in the practice of administering anti-inflammatory agents. This is commonly done for inflammatory joint conditions such as rheumatoid arthritis, psoriatic arthritis, gout, tendonitis, bursitis and, occasionally, osteoarthritis.
With the additional ultrasound capabilities, users can visualise the introduction of fluid to confirm the correct needle placement.
Does the knee trainer allow for suprapatellar bogginess simulation?
Yes, an accumulation of fluid in the suprapatellar region can be created, this will indicate positive results for ballottement.
