Hip Implant and Knee Implant Surgery


Surgical site infections within 90 days of surgery (Hip implant and knee implant surgery)

A Surgical Site Infection (SSI) refers to an infection that occurs where an incision is made on the skin for a surgical procedure. It happens when micro-organisms enters and multiplies at the surgical site. An SSI can range from a superficial wound infection to life-threatening complications involving soft tissue, organs or on the implants. Most SSIs develops within 90 days post-surgery.

In KTPH, we have implemented processes for the prevention of SSI. They include pre-operative antiseptic showering, pre-operative hand and forearm antisepsis and patient skin antisepsis measures.

Hip Implant Surgery

Hip implant surgery is a common treatment for a hip fracture. A fracture of the hip can limit mobility and decrease quality of life. Hip implant surgery can be a total hip replacement or a hemi (half) hip replacement. A hip implant surgery may last from 1 to 2 hours and most patients will be able to sit and stand as early as 1 to 2 days after surgery.

Knee Implant Surgery

Knee implant surgery is recommended to patients with severe knee pain and walking difficulty caused by knee conditions such as osteoarthritis, rheumatoid arthritis or traumatic injury. The patient’s damaged part of the knee is replaced with an implant. Like the natural knee joint, knee implants will also experience wear and tear from usage and patients may need a subsequent revision of component surgery. Similar to the Implants, it can be done as a total or partial replacement.

Indicators Update

From January 2016 to April 2018, the mean rate of SSI within 90 days of hip implant surgeries was 0.3% (n=2), which is lower than international standards of 12.8% (Brazil, 2015). For SSI following a knee implant surgery, KTPH's mean rate of 0.9% (n=4) is lower than the international rate of 6.7% (Brazil, 2015).
