About this study

Objectives:

A. To evaluate the effectiveness of electrocoagulation:

  • To measure the reduction in intraoperative bleeding volume when using electrocoagulation.
  • Analyse the impact of electrocoagulation on surgical visibility and accuracy during implant placement.

B. Comparison of surgical outcomes:

  • Investigate the incidence of intra- and postoperative complications, such as incidental vascular-nerve injury, wound infections, deep vein thrombosis, and implant-related problems, in patients operated on with electrocoagulation versus techniques without electrocoagulation.
  • Examine the influence of haemostatic technique on the need for blood transfusion during or after surgery.
  • Evaluation of long-term functional outcomes and patient satisfaction, including joint stability and range of motion, in both groups.

C. Review of patient recovery and period of hospitalization:

  • Analysis of the impact of electrocoagulation on length of hospitalisation, and time to ambulation.
  • Assessment of postoperative pain levels and analgesic medication use between the two groups.
  • Patients' return to daily activities and overall quality of life after surgery.

D. Comparison of data obtained with other studies conducted internationally.

Primary outcomes

  1. Knee Injury and Osteoarthritis Outcome Score (KOOS) knee subjective score

    Time frame: the test will be administered pre operation, 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, score is on a scale, higher values mean a worse outcome, scale 0-168

  2. Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) subjective score

    Time frame: the test will be administered pre operation, 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, score is on a scale, higher values mean a worse outcome, scale 0-96 .

  3. International Knee Documentation Committee (IKDC) objective form

    Time frame: the test will be administered pre operation, 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, score has different classifications on a scale from A to D, the latter being the worse outcome .

  4. Harris Hip Score

    Time frame: the test will be administered pre operation, 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, score is on a scale, higher values mean a better outcome, scale 0-100 .

  5. Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR) hip subjective score

    Time frame: the test will be administered pre operation, 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, score is on a scale, higher values mean a worse outcome, scale 0-24 .

  6. Forgotten Joint Score

    Time frame: the test will be administered 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, score is on a scale, higher values mean a worse outcome, scale 0-48 .

Secondary outcomes

  1. hemaglobin levels

    Time frame: the hemaglobin levels will be registered pre-operation, then post-op day: 1, 2, 3, 4, and 5. Then at 2 weeks post-operation, 6 weeks, and 3 months

    for blood loss objectification .

  2. leucocyte levels

    Time frame: the leucocyte levels will be registered pre-operation, then post-op day: 1, 2, 3, 4, and 5. Then at 2 weeks post-operation, 6 weeks, and 3 months

    for infection objectification .

  3. thrombocyte levels

    Time frame: the thrombocyte levels will be registered pre-operation, then post-op day: 1, 2, 3, 4, and 5. Then at 2 weeks post-operation, 6 weeks, and 3 months

    for blood loss objectification .

  4. mobilisation intervals of the patient

    Time frame: through hospital stay of patient approximatively 4-7 days

    the investigators will asses the time for the self-mobilisation of the patient to sit at the bed's edge, and then mobilisation with a walking aid like a walking frame. .

  5. joint hyperextension angle

    Time frame: the measurements will be registered pre-operative, then 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, the measurement will be done with a measuring angle during objective evaluation. .

  6. joint flexion angle

    Time frame: the measurements will be registered pre-operative, then 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op

    to objectify the recovery, the measurement will be done with a measuring angle during objective evaluation. .

  7. genu flexum angle

    Time frame: the measurements will be registered pre-operative, then 2 weeks post-operation, 6 weeks post-op, 3 months post-op, 6 months post-op, 1 year post-op
