      • Pioneered flexible knee replacements in South India.
      • Flexible knee replacements allow knee bending
      • Full bending required for activities like kneeling, gardening recreation.
      Knee Replacements
    • 10. Patients with High flexion Knees All patients had High flex knee replacements
    • 11. Minimally invasive Hip & Knee surgery - What is it?
      • Skin incisions are smaller than conventional surgery
      • It is not Key hole or arthroscopic surgery
      • Inside soft tissue dissection is less.
      • More Bone, tendons, soft tissues are preserved
    • 12.
      • Small incisions that measure 4- 5 inches
      • Cause less pain
      • Less blood loss
      • Less requirement for analgesics
      • Faster recovery
      Minimally invasive knee replacements

    • 16.
      • Increasing number of patients < 50 years seeking knee replacements.
      • Youngest patient so far is 34 years.
      • Patient of 24 years is on waiting list for knee replacement.
      • Special considerations of material, technique needed. Oxinium knee is an example of a TKR for young patients.
      Knee replacements for young patients
    • 17. Journey knee replacement
      • High flex knee prosthesis
      • Only implant in market to reproduce normal knee movements
      • Provides excellent stability
      • Oxinium confers longevity of implant
      • Can be used with patient matched instrumentation ( PMI) allowing accurate implantation
    • 18. Computer assisted Knee replacement
      • Used for outliers
      • Patients with Pre existing bony deformities in the femur or tibia.
    • 19. Patient matched instrumentation( PMI)
      • Alternative to Computer assisted knee replacement- Customized cutting blocks.
      • Used for Journey knee
      • Reduces operating steps and time
      • In the long run will reduce the cost of the implant
      • Requires a standing x ray and MRI scan of the knee.
      • Data sent to Lab in US where cutting blocks are made.
      • Cutting blocks delivered to patient in 3 weeks.
      • Patients travel to India from the US/Canada carrying their own customized cutting blocks.
    • 20. Hip Resurfacing
    • 21. Hip resurfacing- Initial considerations
      • Longevity of any primary THA cannot be predicted Revision remains an issue
      • Young/active patient may outlive primary THA.
      • Hip resurfacing extends continuum of care in young patients with hip disease as a hip replacement is still possible in future.
    • 22.
      • Young and middle aged patients with hip arthritis
      • Pain is severe to need a Hip replacement
      • X-rays show evidence of hip arthritis
      • Bone density is normal
      • Anatomy of hip is normal
      • Limb lengths are equal
      Who is a candidate for hip resurfacing?
    • 23.
      • Metal on metal bearings have longevity
      • More bone preservation in comparison to a total hip replacement
      • Full range of movement & less chance of dislocation.
      • Revision to a total hip replacement is possible later on.
      Advantages of Hip resurfacing
    • 24. Surgical technique Femoral reaming
    • 25. Technique- Femoral head cemented
    • 26. Acetabular reaming & component insertion
      • Uncemented cup
      • Fixationby circumferential fins (Durom)
      • Hydoxy apatite coating
      • Cobalt chrome molybdenum
      • High carbon content

    • 31. Birmingham Hip Resurfacing American patient story Short Video
    • 32. Indications for Proxima or short stem Hip replacement
      • Any patient with Hip arthritis for whom a total hip replacement is the permanent solution but Proxima will preserve more bone than a total hip replacement. Bone stock should be intact.
      • Those patients with disease in the head which is more extensive making “ Resurfacing” unsuitable. For eg- Avascular necrosis
    • 33. Short Stem Hip replacement
    • 34.  
    • 35. Proxima is a bone preserving hip replacement
      • Neck portion of femur is preserved
      • Only head is removed.
      • The shaft of the femur is not entered or reamed, once again preserving bone.
    • 36.
      • Alternative to hip resurfacing & total hip replacement.
      • Head portion of the femur is not anatomical
      • Short stem is impacted into the upper portion of the femur.
      • No thigh pain vs THR
      • Versatility- Can assemble variety of head size and material
      • Less incidence of dislocation
      • Minimally invasive procedure
      Mini or short stem hip replacement
    • 37. Comparison of total hip & Proxima
      • Total hip removes the neck portion
      • In short stem replacement neck portion is preserved
      • Reaming of the upper femur.
    • 38. Advantages of Proxima
      • Less soft tissue dissection
      • Less bony resection
      • Large diameter Head- less chance of dislocation
      • Fluid film lubrication – leads to less wear of the implant
      • Metal on metal bearings- less wear
      • Hence less is More
    • 39. Short stem or mini hip replacement- American patient story Short Video
    • 40.
      • Shoulder resurfacing is an effective alternative to replacement
      • Most patients with shoulder arthritis can have a resurfacing rather than a replacement
      • Resurfacing preserves more bone than a replacement.
      • Approach is less invasive than that for shoulder resurfacing.
      Shoulder resurfacing
    • 41. Shoulder resurfacing
      • Short video
    • 42. Cartilage & Bone renegeration
      • Cartilage regeneration possible for small to medium cartilage defects
      • Young patients with post traumatic cartilage lesions will benefit.
      • 3 step procedure – Cartilage harvest from knee, culture in lab and re implantation
      • All steps are done in India
    • 43. Cartilage regeneration
      • Chondron therapy- Suited for Post traumatic cartilage lesions, osteochondritis dissecans,
      • Lesions measuring 2- 8 cm are ideally treated
      • Regeneration of normal cartilage occurs
      • May prevent progression to end stage osteoarthritis
    • 44. Bone regeneration
      • Bone forming cells can heal Non unions of fractures, avascular necrosis
      • Bone regeneration done in 3 step procedure.
      • Biological alternative to Hip resurfacing in early cases of Avascular necrosis.
    • 45. Our Unique selling points
      • Well Qualified & experienced surgeon
      • Direct access to Doctors instead of going thro marketing department- hence personalized care.
      • Affiliated hospitals have state of the art infra structure
