Having demonstrated in Chapter 2 that a fully conforming mobile bearing can minimise polyethylene wear, in this chapter we show that a mobile bearing prosthesis, unconstrained in the sagittal plane, can restore natural mobility and stability. For surgeon readers who are less interested in the theoretical background, it might be advisable to go straight to Chapter 4, Indications, or to start by reading the final section of this chapter, The Loaded Prosthetic Knee. If that proves interesting, the surgeon might attempt The Unloaded Prosthetic Knee. For the more research minded surgeon or engineer, it seems more logical to start with the Unloaded Natural Knee (the longest section of the chapter) and to read from there. The chapter may also be of interest to those surgeons embarking on the use of a bi-cruciate retaining total knee replacement.

Bi-cruciate retaining knee implants are anatomically designed for use in early surgical intervention, for patients with less severe arthritic disease. Patient satisfaction after total knee replacement is directly related to knee stability and proprioception, particularly for high-demand, active patients. While preservation of all intact and healthy ligaments may be the key to achieving such results of satisfaction, balancing four ligaments in a bi-cruciate procedure is more technically challenging then a conventional total knee replacement. Robotics-assisted arthroplasty has been gaining popularity as a tool to increase accuracy and precision of implant positioning. Robotics-assisted systems can provide surgeons with virtual tools to make informed decisions for knee replacement, specific to the needs of the patient. Here, we are introducing a semiautonomous handheld robotic system support for a bi-cruciate retaining knee implant design. The system supports image-free anatomic data collection and streamlined intraoperative surgical planning with dynamic gap balancing before any bone preparation. In this study, we evaluate the surgical technique and accuracy of implant placement in synthetic bone and cadaver experiments.

Posterior Direction

Prosthetic total knee replacements rarely dislocate. When dislocation does occur, it is usually in a posterior direction in association with a posterior stabilised, cruciate-sacrificing prosthesis. Neurovascular injury is unusual. In this report, we describe a case of anterior dislocation of a cruciate-retaining total knee replacement in a 67-year-old woman. The dislocation occurred in the absence of overt trauma and resulted in severe neurovascular injury.

Similarities And Differences

Many pathologic entities can produce a painful total knee replacement (TKR) that may lead to potential prosthetic failure. Polyethylene insert dissociation from the tibial baseplate has been described most frequently after mobile-bearing and cruciate-retaining TKRs. However, only 3 tibial insert dislocations in primary fixed-bearing High-Flex posterior-stabilized TKRs have been reported. We present a new case of tibial insert dislocation in a High-Flex model that shares similarities and differences with the cases reported, facilitating the analysis of the potential causes, which still remain undefined.

Purpose: The purpose of the study was to find the effects of early rehabilitation on high flex cruciate retaining total knee replacement (TKR) on pain and function. Methods: We designed a prospective pre-post trial and evaluated 34 participants who underwent unilateral TKR following end stage knee osteoarthritis. Outcome measure of numeric pain rating scale (NPRS), knee ROM, quadriceps strength and functional measure of timed up and go test (TUG) and six-minute walk test (SMWT) was assessed before and three months post surgery by a blinded observer. Results: The knee flexion ROM showed significant improvement of 25.1∘[Formula: see text]±[Formula: see text]11.2∘ at 3-months. The NPRS, TUG and SMWT showed significant change of 6.47[Formula: see text]±[Formula: see text]0.92, 21.7[Formula: see text]±[Formula: see text]2.6, 157.7[Formula: see text]±[Formula: see text]31 from baseline to 1.3[Formula: see text]±[Formula: see text]0.8, 17.5[Formula: see text]±[Formula: see text]1.6, 263[Formula: see text]±[Formula: see text]37.9 at 3 months respectively following TKR (p = 0.001). Conclusion: Early rehabilitation showed improvement in knee ROM, pain reduction, and accelerated recovery in performing TUG and SMWT.
