A qualitative study of patients' experiences before, during and after surgical treatment for periprosthetic knee joint infection; “I assumed it had to be like that … ”

Background

Periprosthetic joint infection (PJI) of the knee is associated with extended hospital stay, high doses of antibiotics, lengthy rehabilitation, and pain. Standard treatment is a two-stage procedure comprising two surgeries and two hospitalizations. To facilitate exploration of patients’ perspectives, the qualitative study presented here was an adjunct to a Danish randomized controlled trial comparing one-stage and two-stage revision surgery.

Aim

To explore patient experiences, before, during and after hospitalization and surgical treatment with one- or two-stage revision for PJI of the knee.

Material and methods

Qualitative, semi-structured telephone interviews were conducted with 10 individuals who had undergone either one- or two-stage revision because of PJI. Thematic analysis was employed.

Results

The essence of the findings was that the infection was a transition point in a possible life-changing illness. The three themes representing this comprised: 1) physical, 2) psychological, and 3) social implications. Each theme is further illuminated with subthemes.

Conclusions

Infection is a transition point in a possible life changing illness. Late diagnosis and delayed treatment are major issues. Individuals suffer from pain, weight loss, fatigue, and reduced mobility as well as dependency on family members, leading to psychological challenges including depression.

Implications for clinical practice

Patients with PJI of the knee could be better informed, educated and involved before and during treatment. Information is needed not only about the physical consequences, but also the psychological and social consequences. More patient involvement and inter-professional and care sector coordination is important when caring for patients with PJI.
