Brief summary

The purpose of this study is to investigate whether our standard practice of injecting local anaesthetic into the knee joint for total knee replacements impacts knee range of motion at 6 weeks post operation for total knee replacement. We hypothesize that local infiltration analgesia during operation in total knee replacements negatively impacts the knee range of motion.

Interventions

Our intervention will be the surgeon’s standard practice of 200mg of naropin (ropivacaine) and 0.5mg of adrenaline, used as local infiltration analgesia injected around the joint replacement in TKA.

Inclusion criteria

All patients with a diagnosis of osteoarthritis undergoing bilateral total knee arthoplasty

Exclusion criteria

Patients with allergies to any of the used analgesic agents, patients unable to undergo a femoral sheath or sciatic nerve block. Patient’s with prior surgeries on their knee, for example prior knee arthroscopies, high tibial osteotomy, tibial or femoral nail, open reduction and internal fixation of the distal femur will all be excluded from the study. Patients with either a varus or valgus knee deformity were excluded from the study.
