Outcome of revision UKR to TKR when compared to a matched group of TKR of same total arthroplasty lifespan

Expanding Robotic Arm-Assisted Knee Surgery: The First Attempt to Use the System for Knee Revision Arthroplasty

“…Robotic arm-assisted arthroplasty was introduced in Orthopaedics in 2006, representing a haptic tactile system and since then has expanded its applications into unicompartmental knee (UKA), total knee, and hip arthroplasty [1]. Regarding UKA, robotic arm-assisted procedures have shown to overcome technical challenges associated with manual partial knee procedures, increasing accuracy in recreating the posterior tibial slope and coronal tibial alignment and, therefore, leading to better midterm clinical outcomes [6,7,[10][11][12]. Regarding THA, studies have shown…”

Does Partial Knee Replacement Allow Return to High-Demand Activities?

“…Recent studies reported results for PKR, unilateral knee replacement (UKR) [1][2][3][4][5][6][7][8][9][10], contrasts between mobile-bearing versus fixed-bearing, and cemented versus cementless implants. It has been suggested that UKR improves range of motion and functional recovery as well [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The term PKR is used to describe the replacement of the medial compartment, lateral compartment, or patellofemoral joint (PFJ).…”

“…The term PKR is used to describe the replacement of the medial compartment, lateral compartment, or patellofemoral joint (PFJ). It is generally agreed that PKR offers good function enhancement [2][3][4][5][6][7][8][9][10][11][12]. Furthermore, PKR is a well-established treatment option for end-stage unicompartmental (medial, lateral, or patellofemoral) osteoarthritis of the knee, after the failure of conservative measures.…”

“…The National Joint Registry shows the number of PKR performed varies significantly amongst surgeons [15][16]. It has been shown that high-volume PKR surgeons and units have better outcome data and that surgeons should perform more than a minimum number of partial knees a year to show good implant longevity [8][9][10][11][12][13][14]. Some studies have quoted an improved range of movement and PROM as well as returning to their preferred sporting activity [3][4][5][6][7][8][9][10][11][12][13].…”

“…There has been an increasing interest in maximum function with more modern PROM scores trying to address ceiling and floor effects [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, there is little data available as to what specific level of activities that patients are able to return to following PKR [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Many studies focus on PROM data and survivorship as outcome measures [11][12][13][14].…”
