Limb-Length Discrepancy After Hip Replacement
Around 62% of hip replacement patients experience 9 mm of leg lengthening; most stop noticing it within a year as soft tissues adapt, a trade-off surgeons accept to reduce dislocation risk.
Practical reading from Professor Paul Lee and the Lincolnshire Hip Clinic team on hip replacement, recovery, surgical technique and what to expect from your £17,800 fully inclusive package.

Around 62% of hip replacement patients experience 9 mm of leg lengthening; most stop noticing it within a year as soft tissues adapt, a trade-off surgeons accept to reduce dislocation risk.

SPAIRE hip replacement preserves the obturator internus tendon, which functions as an immediate mechanical strap stabilising the prosthesis rather than requiring the 90-day healing period of standard techniques. This day-zero stability is the basis for safe same-day discharge.

SPAIRE hip replacement leaves posterior tendons intact, providing on-table stability without post-operative restrictions, but narrows surgical exposure. Mako robotic sub-millimetre cup positioning compensates: each technique solves what the other cannot, together addressing both soft-tissue and geometric dislocation pathways.

Joint pain after hip replacement typically resolves within six to eight weeks, though surrounding muscles and soft tissue require three to twelve months to fully remodel — two recovery timelines that often leave patients thinking they have finished before the deeper adaptation is complete.

The hip implant is identical across all surgical approaches, with equivalent long-term survival rates of approximately 58 per cent at 25 years; approach selection determines the recovery journey — muscle handling, movement restrictions, and short-term complication risks.

Hip resurfacing caps the femoral head to conserve bone; total replacement removes it — a technically simpler approach with wider applicability. Both achieve excellent long-term function, though choice depends on bone quality, age, activity level, and surgeon expertise.

SPAIRE hip replacement preserves the piriformis and obturator internus muscles instead of dividing them, maintaining mechanical stability and the joint's position sense to reduce dislocation risk.

Standard posterior hip replacement requires six to twelve weeks of movement restrictions for tendon repair to heal; SuperPATH and SPAIRE each eliminate this period through different mechanisms — SPAIRE by preserving key tendons, SuperPATH by avoiding joint dislocation.

SPAIRE and STAR preserve the piriformis tendon during posterior hip replacement, stabilising the joint immediately and eliminating the movement precautions traditional approaches require.
