The Stanmore Implants METS (Modular Endoprosthetic Tumour System) is a modular titanium endoprosthetic system designed for the reconstruction of large bone defects, typically following tumour resection, severe trauma, failed joint replacements, or failed massive allografts. Distributed by Stryker, the METS system was introduced in 2001 and encompasses reconstruction solutions for the proximal femur, distal femur, total femur, proximal tibia, proximal humerus, and pelvis.

The SMILES (Stanmore Modular Individualised Lower Extremity System) knee is the platform knee component of the METS system. The knee is based on a rotating hinge design with a long clinical track record, and a fixed hinge option is also available for cases of marked instability or gross deformity.

System Overview:
Manufacturer: Stanmore Implants Worldwide Ltd. (a Stryker company)
System Name: METS Modular Endoprosthetic Tumour System — SMILES Knee
Indications: Primary bone tumours, metastatic bone disease, severe trauma, revision knee arthroplasty, failed massive allografts, failed massive replacements
Construction Material: Modular titanium construction
Resection Increments: 15mm modular increments
Distal Femur Resection Range: Minimum 76mm, Maximum 263mm

SMILES Knee Tibial Options:
Option 1 — Rotating Hinge Polyethylene Tibia: Recommended for routine primary cases where tibial cortical bone is strong
Option 2 — Rotating Hinge Metal Cased Tibia: Suited to revision cases with reduced stability or where tibial plateau plates are required to maintain joint line height
Option 3 — Fixed Hinge Tibia: For knees with marked instability or gross deformity; available in short and long stem configurations
Tibial Sizes: Small and Standard

Key Features:
- Minimises the number of modular components, reducing fretting
- Contoured metal-on-plastic bearing surfaces to reduce friction and wear
- Rotational laxity reduces torsional stress at the cement/bone interfaces
- Components connect via interlocking taper junctions with anti-rotation lug for quick, secure assembly
- Hinge allows a few degrees of hyperextension to compensate for quadriceps weakness
- Optional hydroxyapatite (HA) coated collar available to reduce loosening
- Tibial plateau plates allow adjustment of joint line height
- Minimal specialised instrumentation required for a clutter-free operating theatre
- Custom implants available with short turnaround times for complex cases

Trial Set Purpose:
The METS SMILES Knee Trial Set is provided to enable intraoperative sizing and trialling of femoral and tibial components prior to definitive implant selection. Instrumentation is supplied non-sterile in surgical trays intended for reprocessing prior to use.
