Surgery designed for your anatomy. Not the average.
The right joint replacement depends on the joint — and the right operation for a younger patient is rarely the same as for an older one. Dr Yas matches the operation to the patient: preserving your own joint where possible, and personalising it where a full replacement is right.
- Joint-preserving partial & bicompartmental knee replacement
- Personalised total knee replacement — kinematic alignment, minimal ligament release
- Direct anterior hip, 3D planning & bone-preserving short stems
- Built to substantially exceed the “one in five” dissatisfaction average

Most knees do well. Dr Yas aims higher.
Published satisfaction rates after standard total knee replacement sit at around four in five — meaning roughly one in five patients say they are not fully satisfied. That figure reflects an average across standard total replacements done to a standard mechanical alignment. Dr Yas does not accept it as the standard to work to.
Satisfaction is substantially higher in patients matched to the right operation for their joint — partial replacement where suitable — and in patients who receive personalised total replacement with kinematic alignment and minimal soft-tissue release.
Preserve what’s healthy. Personalise the rest.
The knee is one of the most complex joints in the body — six independent motions, four ligaments, three working areas, and a sliding kneecap. Treating it as a single standard problem misses what makes your knee unique.
Joint-preserving partial
Where arthritis is limited to one or two of the three areas, partial or bicompartmental replacement preserves the rest of the joint — including your own ligaments — for a more natural-feeling knee and a faster recovery than full replacement.
Personalised total
Where a total is right, kinematic alignment positions the implant to follow your own natural pre-arthritic alignment, planned and executed with robotic-assisted technology to millimetre precision.
Minimal ligament release
Over-releasing soft tissue is a recognised cause of unhappy knees. Dr Yas keeps ligament release to the minimum necessary — fitting the implant to the knee, not the knee to the implant.
Kinematic alignment, planned with robotic precision
Where a total knee replacement is the right answer, Dr Yas positions the implant to follow your own natural alignment, rather than forcing the joint to a standard target — planned and carried out with robotic-assisted technology to millimetre precision.
Direct anterior hip & 3D planning
Hip replacement is one of the most successful operations in modern medicine, and its most significant refinements of the last twenty years are standard at Dr Yas’s practice.
- 1
Direct anterior approach
A muscle-sparing technique worked between the natural planes of the hip muscles at the front — faster early recovery (many patients walk on the day of surgery), less post-operative pain, and a lower early dislocation risk than traditional approaches.
- 2
3D pre-operative planning
Dislocation risk, leg-length and tissue impingement are planned on detailed 3D imaging before any cut is made — what used to be judged in theatre is now decided beforehand.

Bone-preserving short stems
Where suitable, short-stem implants retain more of your own femoral bone — valuable for younger patients who may need a revision later in life.
Told you’re “too young” to do anything?
Patients under 50 with single-area knee arthritis are commonly told they must wait. The unspoken cost is significant — work gets harder, weight is gained from forced inactivity, fitness and confidence decline, and the knee often deteriorates further. Where partial knee replacement is technically appropriate, it offers a genuine solution: a smaller operation, faster recovery, and preservation of the rest of your joint, including your ligaments and most of your bone.
