What is the newest procedure for total knee replacement?

What is the newest procedure for total knee replacement?

Minimally-invasive quadriceps-sparing total knee replacement is a new surgical technique that allows surgeons to insert the same time-tested reliable knee replacement implants through a shorter incision using surgical approach that avoids trauma to the quadriceps muscle (see figure 1) which is the most important muscle …

What is the best knee replacement surgery?

A TKR is now among the safest and most effective of all standard orthopedic surgeries. During a TKR, a surgeon removes the surface of your bones that have been damaged by osteoarthritis or other causes and replaces the knee with an artificial implant that is selected to fit your anatomy.

What percentage of knee replacement surgeries are successful?

Surgeons have performed knee replacements for over three decades generally with excellent results; most reports have ten-year success rates in excess of 90 percent.

How long are you laid up after knee replacement surgery?

Most people with sedentary employment can return to work after 4–6 weeks, but if your job involves heavy lifting, you may need to wait 3 months to resume work. It can take 6–12 months to get back to full activity levels. Click here to find a timeline for recovery after a TKR.

What happens at 5 months after knee replacement?

The conventional wisdom, and most clinical literature, agree that at five months after knee replacement it is unlikely to see much gain in flexion (bending the knee back). It is understood that knee replacement patients have until three months to improve their flexion, and six months to finish off their knee extension.

Is TKR a major surgery?

Who is offered knee replacement surgery. A knee replacement is major surgery, so is normally only recommended if other treatments, such as physiotherapy or steroid injections, have not reduced pain or improved mobility.

When does stiffness stop after TKR?

By 6 weeks, pain and stiffness should continue to resolve, and isokinetic quadriceps and hamstrings strengthening exercises can be incorporated. By 3 months, most TKA patients should have achieved greater than 90% of their ultimate knee motion and pain control.

What is Subvastus approach?

The subvastus approach (Fig. 1, Right) is a truly “quadriceps-sparing” surgical technique. The entire quadriceps muscle is left intact. As you would expect, patients who have a total or partial knee replacement with the subvastus approach have less pain, better muscle control and overall faster recovery.

What is an advantage to a lateral approach knee replacement?

Lateral approach can directly adjust the tight structure, and also less vascular compromise to the patella than medial approach with lateral patellar release. Less invasiveness to the quadriceps muscle in lateral approach could result into better range of motion after the surgery.

Can you do joint mobilizations on a TKA?

Joint mobilization techniques for rehabilitation are commonly employed by physical therapists to relieve pain and increase motion in TKA patients.

What is Parapatellar approach?

The lateral parapatellar approach provides a good view of the articular surface of the distal femur. With a longitudinal division of the quadriceps tendon and extensor mechanism, the patella can be dislocated medially.

What is Nano knee surgery?

A streamlined, minimally-invasive surgery that restores the damaged compartment of your knee and preserves the healthy areas.

What is valgus deformity?

Valgus knee deformity is defined as a tibio-femoral angle of greater than 10°. Typically, the deformity is the result of changes to both the bony and soft-tissue components around the knee.

What is rehabilitation protocol of post-operative knee replacement?


  • Begin to incorporate activity specific training (i.e. household chores, gardening, sporting activities).
  • Low impact activities until week 12.
  • No twisting, pivoting until after week 12.
  • Patients should be weaned into a home/gym program with emphasis on their particular activity/sport.
