Global Journal of Orthopedics | Vol 1, Issue 1

Table 1. Types of Hip Prostheses.

Material/DesignBiomechanical AdvantagesLimitationsReferences
CoCrMoHigh strength, superior wear and fatigue resistanceHigh elastic modulus, stress shielding[1,2,5,18]
Titanium AlloysLow modulus, high biocompatibility, osseointegrationLess wear resistance than CoCrMo[6,7,15,16]
PEEKBone-like modulus, radiolucency, reduces stress shieldingLimited clinical long-term data[9,10]
PCD CoatingsOptimal stress distribution, high hardness, low frictionHigh manufacturing cost[10,32]
CoC BearingsLow wear, inert, ideal for young/active patientsPotential for squeaking, higher cost[11,12,19,20]
CoP BearingsLower wear than MoP, improved patient-reported outcomesStill releases some particles[19,24]
Dual MobilityEnhanced ROM, prevents dislocations, good long-term survivalIncreased acetabular volume required[13,14,19,24]
Lattice StructuresBetter load distribution, promotes osseointegrationRequires advanced manufacturing processes[17,28,30]
Additive ManufacturingHigh customization, precise anatomical matchingCost, technical complexity[20,30,31]
Patient-specific ImplantsImproved fit, reduced impingement and revision riskRequires imaging and custom planning[21,30]
