The implant is only half the job. The other half is making sure it is in your theatre when the patient is on the table.
Decima Group Limited is the exclusive Tanzanian distributor of JUST Medical hip and knee systems, the joint reconstruction range built in Tianjin since 1958 and proven on German test benches. You get the implants, the full instrument trays, the trials, and a specialist standing in your theatre. From one accountable partner.
Exclusive hip & knee distribution and theatre support for Tanzania



A cancelled joint case is not an inconvenience. It is money, theatre time, and trust walking out the door.
The patient is consented and starved. The team is scrubbed. Then the wrong size shows up, the trial is missing from the tray, the revision component nobody ordered is suddenly needed, and the case is cancelled. The patient goes back to the ward. The slot is wasted. Your waiting list grows. And the surgeon remembers exactly who let it happen.
An arthroplasty case does not begin at the incision. It begins weeks earlier, when somebody makes certain the right implant, the right sizes, and the right instruments are confirmed and in the building. That somebody is Decima.

Pedigree you can point to, not a brochure claim.
JUST Medical (Just HuaJian Medical Devices, Tianjin) has built hip and knee implants since 1958. The range runs deep: four hip systems across more than 40 series and over 1,000 specifications, and four knee systems across 7 series and over 600 specifications. That depth is the difference between "we think we have your size" and "your size is confirmed."
This is not marketing. The polyethylene inserts are made from German UHMWPE raw material meeting ISO 5834-2 and ASTM F648. Wear testing is run at EndoLab in Munich, where the JUST knee recorded a wear rate of 5.79 mg per million cycles against a database mean of 12.37. The manufacturing carries GMP, ISO, CE, CFDA and FSC certification.

The questions theatre managers and procurement always ask.
"Will the size I need be there?"
That is the whole point. We confirm sizes and stage trials before the case, with a range either side. Send the case and we plan it with you.
"What if a primary becomes a revision?"
The JUST Medical revision platform is held on standby. SEE, ASM, RSL stems, revision cups, augments and sleeves, ready when the table changes.
"Is the quality real or just cheap?"
German UHMWPE, EndoLab wear data below the database mean, BIOLOX delta ceramic heads, and GMP, ISO, CE certification. Documentation on request.
"Who supports the surgeon in theatre?"
We do. A Decima specialist attends the case for sizing and technique, and we train your team on the instrument system.
Product availability and configurations are subject to registration and specification. Clinical use should follow hospital protocols, surgeon judgement and applicable regulatory requirements. Technical details should be confirmed with the Decima product team. JUST Medical and product names are trademarks of their respective owners.
