From the Guidelines

Infection after hip labrum repair can occur at any time, but it is most commonly seen within the first 3 months post-operatively [ 1 ].

Typically, signs of infection such as increased pain, redness, swelling, warmth, and drainage may appear within 2-6 weeks after surgery.

In some cases, infection can be delayed and present 6-12 months or even years after the procedure.
As a precautionary measure, patients are usually prescribed antibiotics such as cefazolin 1-2 grams intravenously 30-60 minutes before surgery, and in some cases, oral antibiotics like ciprofloxacin 500mg twice daily for 5-7 days post-operatively [ 1 ].
It is essential to monitor patients closely for any signs of infection and to have a low threshold for ordering diagnostic tests such as complete blood counts, erythrocyte sedimentation rates, and C-reactive protein levels if infection is suspected [ 1 ].

C-reactive protein (CRP) levels can be elevated after surgery, but generally return to baseline values within 2 months after surgery [ 1 ].
Joint aspiration has been found to be extremely useful in diagnosing joint infection after surgery [ 1 ].
Synovial fluid alpha-defensin tests have also been shown to be highly accurate in the diagnosis of prosthetic joint infection [ 1 ].

From the Research

The typical timeframe for infection after hip labrum repair is not directly stated in the provided studies, as they primarily focus on hip arthroplasty and hemiarthroplasty procedures 2, 3, 4, 5.
However, study 6 discusses arthroscopic treatment of calcification with surrounding inflammation in the hip labrum, but it does not provide information on the timeframe for infection after hip labrum repair.
Studies 2, 3, 4 mention late infection, which is defined as more than 3 months after surgery, but this is in the context of hip arthroplasty and hemiarthroplasty, not hip labrum repair specifically 2, 3, 4.
It is essential to note that the provided studies do not directly address the question of the typical timeframe for infection after hip labrum repair, and therefore, no specific timeframe can be determined from the available evidence.

Several studies identify risk factors for infection after hip arthroplasty and hemiarthroplasty, including posttraumatic osteoarthritis, previous surgery, chronic liver disease, corticoid therapy, and excessive surgical time 2, 3, 4.
Other risk factors mentioned include obesity, female gender, glucocorticoid and immunosuppressant treatments, prolonged surgical time, inadequate antibiotic prophylaxis, prolonged wound drainage, hematoma, dislocation, and cutaneous, urinary, and/or abdominal infections 2, 3, 4.
These risk factors may be relevant to hip labrum repair, but the provided studies do not specifically address this procedure.

Study 6 reports significant improvement in symptoms and hip joint function after arthroscopic treatment of calcification with surrounding inflammation in the hip labrum.
Study 5 describes a care bundle that includes pre-operative bleeding risk assessment, double preparation and draping, broad-spectrum antibiotic agents, tranexamic acid, meticulous hemostasis, and watertight wound closure, which contributed to a significant reduction in surgical site infection rates.
These findings may be relevant to infection prevention in hip labrum repair, but further research is needed to determine their applicability to this specific procedure.
