Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomisation comparing distal femur M-O-M TiN/silver Uncoated prosthesis (MUTARS) distal femur prosthesis. MUTARS segmental distal femoral implants with galvanised silver coating. Femoral implant surgery will be stratified between trauma, joint replacement and tumour surgical patient groups. Surgery will be conducted by qualified orthopaedic surgeons. Intervention will be delivered surgically once over a period of at least 2 hours, depending on the extent of patient anatomy and surgery time required. Infection will be assessed by clinically trained professionals (e.g. nurse and doctor) and presence or absence of infection will be recored at 2,5,14 & 30 days, 6 months, 1 year and 2 years. Patient reported outcomes will be collected 1, 6,12 and 24 months.

Outcomes
Primary outcome [1] 335170 0
The primary outcome of this study is to assess surgical site infection (SSI) prospectively by qualified medical or nursing staff, with the presence or absence of infection recorded at 2, 5, 14, 42 days, 6 months, 1 year and 2 years postoperatively.
Timepoint [1] 335170 0
2, 5, 14, & 42 (+/-2) days, 6 months, 1 year and 2 years postoperatively across all patient strata groups, or at any time a clinical indication of infection arises as determined by qualified medical staff.
Secondary outcome [1] 423385 0
Composite secondary outcomes will be assessed by determining any change in the incidence of secondary surgeries including wash out, soft tissue coverage, implant revision and amputation by audit of patient medical records postoperatively.

Summary
Brief summary
This trial is exploring the efficacy of coating limb implants with a galvanised silver layer for the prevention of surgical site infection.

Who is it for?
You may be eligible for this study if you are an adult who has undergone resection of primary or secondary musculoskeletal malignancy, and require subsequent segmental bone reconstruction of the distal femur. In addition, there will be other participant groups recruited including those requiring reconstruction following trauma or implant failure.

Study details
Participants will be randomly allocated to receive implants with or without a galvanised silver coating. The surgery will be performed by an orthopaedic surgeon. Participants will be asked to attend follow-up appointments for up to 2 years after the surgery to establish whether any surgical site infection or other complications have occurred.

It is hoped that information from this study will establish the utility of silver-coating limb salvage implants in reducing the risk of surgical site infection
