Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Hip stem prosthesis

Experimental: Intervention group - Insignia hip stem study group


Treatment: Devices: Hip stem prosthesis
The Insignia hip stem prosthesis will be used in cementless total hip replacement surgery (THA). The surgery typically takes approximately two hours. All study participants will receive the Insignia hip stem and compatible components. Experienced Orthopaedic Surgeons trained in THA will perform the surgeries as per the standard surgical technique guide for this prosthesis.
