Aim: Total knee arthroplasty (TKA) in valgus knee is more difficult than in well aligned or varus knee, The correction of deformities and ligament balancing are the priority. The aim of this study was to evaluate our experience on 20 knees treated with Advance TKA. Methods: The study group is based on 20 consecutive patients who underwent primary TKA using cemented prosthesis fixation and a medial pivot implant. Study participants included 14 women and 6 men with a mean age of 69.6 years (range, 60 to 82 years). Osteoarthritis (80%) was the most common diagnosis rheumatoid arthritis (16%), and other findings (4%). All patients received the Advance TKA (cruciate ligament sacrificing) prosthesis (Wright) using cemented fixation. Results: Twelve knees were rated excellent, 8 as good. The femorotibial mechanical axis was corrected from a valgus of 15° to 5° in postoperative. There was no varus-valgus instability in 18 knees, and 2 knees had approximately 5° varus-valgus instability in extension. There was palpable, non-painful, patellofemoral crepitus noted in one knee. Conclusion: The Advance TKA (with cruciate ligament sacrificing) prosthesis (Wright) with cemented fixation was successful in primary arthroplasty in valgus knees, also in severe deformities with incompetent medial collateral ligament.

Timing of surgery varies between patients. It is generally recommended that patients have surgery within 6-8 weeks post injury. You must have regained a full range of motion of the knee joint and most of the swelling must be resolved prior to surgery. Some patients have an injury to the medial collateral ligament (MCL) as well as the ACL tear and require a period of knee bracing pre-operatively to allow the MCL to heal. I do not perform the surgery until stiffness is fully resolved.

AB - A total knee has been designed to mimic less-compliant medial and more-compliant lateral behavior. In vivo testing compared open-kinematic chain behaviors of cadaver knees in their normal state and after implantation of the knee prosthesis. Specimen's limbs were computed tomography scanned, and infrared arrays on tibia and femur were registered to bone markers. Motion of the joint and quadriceps force were reported from 90° flexion to full extension. Less medial and more lateral anterior-posterior motion was seen in both the intact and the implanted knees. Tibiofemoral rotation and translation were similar in direction but were reduced in magnitude for the prosthetic knees. Quadriceps force, defined as that applied force required to extend the knee, required after implantation was variable between specimens but not statistically different from the intact condition. The prosthesis tested exhibits kinematic behavior similar to that in their normal state, with no difference in quadriceps force required for extension.

The LARS ligament has received a lot of media publicity following its use in some high profile athletes. Only short-term outcomes were available. There are surprisingly few studies reporting on LARS ligament outcomes. Only short term outcomes are available. We do know that shedding of synthetic debris from this ligament inside the knee can cause synovitis and predispose to early arthritis. It is my preference to not use the LARS ligament for primary ACL reconstruction.

There are many misleading statements in the media , on the internet as well as claims made by providers who claim that certain tablets, injections or even stem cells can reverse the arthritis process. Unfortunately most of these claims are completely false. There is NO scientific literature evidence that proves that by taking a certain tablet or having an injection into your knee, you arthritis will resolve. There is nothing that can stop a knee joint that has started to wear out from continuing to wear out. There are measures however that can assist with pain management before surgery is indicated.

Arthritic knees that require surgery usually require a Total Knee Replacement. A unicompartmental or “half knee” replacement is reserved for a select few patients who have knee arthritis isolated to one area of the knee joint and who satisfy other preoperative criteria. The revision rate of a unicompartmental knee replacement is significantly higher that a total knee replacement (16% vs 6% at 11 yrs) and therefore there are strict requirements in patient selection.
