Objectives

The primary objective of this tender is to procure certified, high-quality modular orthopedic knee joint components to support patient rehabilitation and mobility within the provincial public healthcare system. The procurement aims to secure a compliant supplier who can deliver consistent product quality, meet strict clinical specifications, and provide post-delivery warranty support while adhering to national preferential procurement policies.

Scope

The contract covers the one-off supply and delivery of 150 units of Modular Single Knee Axis Joints with a locking option. The scope includes physical delivery to the designated Orthopaedic Services facility, submission of pre-award samples for compliance verification, and provision of a two-year replacement warranty. Pricing must remain firm for a 90-day validity period. Evaluation follows a three-stage process: administrative compliance, sample conformity testing, and final scoring based on price (80 points) and preferential procurement goals (20 points for historically disadvantaged ownership).

Technical Requirements

Bidders must supply knee axis joints that strictly conform to the following specifications:

• Connections: Pyramid adaptors for both proximal and distal mounting interfaces.
• Material: Medical-grade stainless steel construction.
• Mechanism: Roller bearing knee axis bushing for smooth articulation; automatic locking at full extension assisted by an extension spring.
• Dimensions & Weight: Flexion angle of 120°; total length between 108mm and 110mm; height from knee centre to pyramid upper edge between 35mm and 38mm; maximum unit weight of 700 grams.
• Locking System: Plastic or nylon lock handle featuring a vertical slot, secured via a 3.6mm chrome-plated stainless steel or brass screw with a laminating lug. Perlon cords attach to either side of the joint using matching screws and connect to the lock handle via a short threaded fitting.
• Cable Specification: 2mm perlon cord lock cable.
• Load Capacity: Engineered for patients weighing up to 125 kg.
• Certification & Warranty: Must hold a C.E Rating and provide a two-year replacement warranty.
• Packaging: Each component must be individually packaged and clearly labelled with the manufacturer’s name or logo.
• Samples: Physical samples must be delivered on or before the closing date for direct specification verification.

Explanation of Technical Terms: “C.E Rating” denotes Conformité Européenne certification, confirming compliance with European health, safety, and environmental standards for medical devices. “Pyramid adaptor” refers to a standardized geometric mounting interface commonly used in modular orthopedic prosthetic systems. “Perlon cord” is a high-tensile nylon-based synthetic fibre utilized for reliable tension and mechanical locking mechanisms in medical hardware.

Skills Requirements

No explicit clinical or surgical skills are required, as this is a goods supply contract. However, bidders must demonstrate proven capability in manufacturing or distributing certified medical orthopedic components, maintaining rigorous quality assurance protocols, and executing timely logistics within the public sector framework. Suppliers must also possess the administrative capacity to comply with South African procurement regulations, including Central Suppliers Database registration, tax clearance validation, and B-BBEE ownership verification. Familiarity with medical device packaging standards and warranty management processes is essential for successful contract execution.
