Knee Replacement
Reconstructing the knee joint.
Knee arthroplasty replaces damaged joint surfaces using femoral, bearing and tibial components, with planning focused on alignment, stability and function.

Replace what is damaged. Restore how you move.
Joint replacement surgery reconstructs severely damaged joint surfaces using carefully selected implant components, with planning focused on alignment, stability, movement and the individual patient.

Recover Progress mobility,
strength and function. When Replacement Is Considered
When the joint itself has become the problem.
Joint replacement may be considered when advanced joint damage causes persistent pain, reduced mobility or major functional limitation, and appropriate non-surgical treatment no longer provides sufficient control.
01 Advanced Osteoarthritis Progressive joint-surface damage
with pain and functional limitation.
02 Severe Joint Degeneration Structural deterioration affecting
mobility and daily function.
03 Selected Post-Traumatic Damage Joint damage following previous injury
may sometimes lead to replacement.
04 Pain + Functional Limitation Symptoms and function matter
alongside imaging findings.
Joint Replacement Options
Reconstructing the knee and hip.
The exact implant and surgical technique depend on the joint, anatomy, degree of damage and individual clinical situation.
Hip Replacement
Reconstructing the ball-and-socket joint.
Hip arthroplasty replaces damaged joint surfaces using acetabular and femoral components selected according to anatomy, bone quality and surgical requirements.
Planning & Precision
A replacement joint is not simply inserted. It is planned.
Joint replacement involves decisions about implant size, position, alignment, fixation, stability and soft-tissue balance. The objective is to reconstruct a functional joint around the individual patient.
Implant Size Components are selected
according to anatomy.
Position Component positioning forms
part of surgical planning.
Alignment Joint mechanics and limb
alignment are considered.
Stability Stability and soft-tissue balance
are assessed during surgery.
Advanced Surgical Planning
Robotic-assisted knee replacement.
Robotic-assisted systems can support selected knee replacement procedures by providing additional anatomical information for surgical planning, bone preparation and implant positioning.
01
Patient Anatomy Planning can incorporate
patient-specific anatomical information. 02
Bone Preparation Technology may support
planned and controlled bone preparation. 03
Implant Position Positioning information can support
execution of the surgical plan. 04
Alignment Information Limb and implant alignment
can be assessed within the operative plan. Robotic assistance supports surgical planning
and execution. The surgeon remains responsible
for the operation and all clinical decisions.
Recovery & Function
Replacement is the operation. Recovery restores function.
Recovery after joint replacement involves progressive mobility, strength and functional rehabilitation. The exact pathway depends on the joint replaced, procedure performed and individual patient.
Mobilize → Restore Motion → Build Strength → Return to Function
Indication The diagnosis matters. Appropriate patient selection
is part of treatment planning.
Planning Technique matters. Implant choice, positioning
and surgical strategy influence reconstruction.
Rehabilitation Recovery matters. Progressive rehabilitation
supports mobility and function.
Outcomes Individual results vary. Expected improvement depends
on the joint and individual factors.
Common Questions
Understanding joint replacement.
When is joint replacement considered? +
Joint replacement may be considered
when advanced joint damage causes
persistent pain and functional limitation,
particularly when appropriate
non-surgical treatment no longer
provides sufficient control.
What is the difference between total and partial knee replacement? +
Total knee replacement reconstructs
the major joint surfaces across the knee. Partial knee replacement may be suitable
in selected cases where damage is limited
to a particular compartment. The appropriate operation depends
on the individual knee.
What is robotic-assisted knee replacement? +
Robotic-assisted knee replacement
uses technology to support surgical planning
and selected parts of operative execution,
including bone-preparation
and implant-positioning information.
Does the robot perform the surgery? +
No. Robotic systems assist
with planning and execution. The orthopedic surgeon remains responsible
for the procedure and clinical decisions.
Which joint replacement implant is best? +
There is no single implant
that is best for every patient. Selection depends on anatomy,
bone quality, joint damage,
surgical requirements
and individual clinical factors.
How long does recovery take? +
Recovery varies according
to the joint replaced,
surgical procedure,
general health
and rehabilitation progress. Detailed knee-replacement recovery
is discussed on the dedicated
Total Knee Replacement page.
Will I need physiotherapy? +
Rehabilitation is commonly
an important part
of joint replacement recovery. The program is adapted
to the procedure
and individual patient.

The right replacement starts with the right indication.
Arrange an orthopedic assessment to understand the condition of your joint and whether joint replacement — or another treatment pathway — may be appropriate.
