“…4,5,7,8,[28][29][30] Although a financial analysis has not been undertaken, our findings do show important differences in inpatient rehabilitation and hospital stay, which will aid healthcare policy makers in the allocation of medical resources and cost planning for the implementation of this technology into clinical practice.…”

AimsThe objective of this study was to compare early postoperative functional outcomes and time to hospital discharge between conventional jig-based total knee arthroplasty (TKA) and robotic-arm assisted TKA. Patients and MethodsThis prospective cohort study included 40 consecutive patients undergoing conventional jig-based TKA followed by 40 consecutive patients receiving robotic-arm assisted TKA. All surgical procedures were performed by a single surgeon using the medial parapatellar approach with identical implant designs and standardized postoperative inpatient rehabilitation. Inpatient functional outcomes and time to hospital discharge were collected in all study patients. ResultsThere were no systematic differences in baseline characteristics between the conventional jig-based TKA and robotic-arm assisted TKA treatment groups with respect to age (p = 0. Total knee arthroplasty (TKA) is an established and highly effective procedure that is performed in over 90 000 patients per year within the United Kingdom.1 The demand for TKA has grown rapidly over the last two decades during which time the overall costs have risen.2 To control this expenditure optimization of postoperative recovery and reducing length of hospital stay, whilst preserving the quality of care, is required. Developments in minimally invasive surgery, pain management, anaesthesia, deep vein thrombosis prophylaxis, antibiotic prophylaxis, implant design and manufacturing and enhanced rehabilitation techniques, have all ultimately focussed on optimizing postoperative recovery and duration of inpatient stay following TKA.2,3 Robotic-arm assisted technology has been used to enhance inpatient recovery and expedite discharge in gastrointestinal, urological, gynaecological surgery, and over the last decade in arthroplasty surgery.

“…However, suboptimal cementing technique may cause mismatch in image-based alignment and postoperatively measured alignment. 23 There is controversy about the optimal postoperative mechanical axis. However, there is agreement that overcorrection in a valgus deformity and undercorrection of <10 degrees varus should be avoided.…”

In recent years, development of computer graphics and haptic feedback technology enabled the use of virtual reality. Virtual reality provides the opportunity to combine 3D visual imagery with interactivity, visual, and tactile realism. Robotic-assisted orthopedic surgery is defined as the use of computers and robotic technology to assist the orthopedist in providing musculoskeletal care, in which machine has the capability of precision and accuracy. Robotic-assisted orthopedic surgery is used in simulating diagnosis, preoperative and intraoperative planning, and actual surgery. One of the main areas for computer-assisted surgical applications is unicompartmental or bicompartmental knee arthroplasty, in which the clinical efficacy is improved by providing enhanced component positioning with dynamic ligament balancing.

“…Recently, Mofidi et al 31 reported on a series of 232 medial UKRs followed retrospectively to assess the accuracy of component placement using the MAKO system. They compared planned intra-operative robotic alignment with post-operative alignment on standardized radiographs and found 70% of prosthesis were inserted within 3 of where intended in the coronal and sagittal planes.…”

Assessment of accuracy of robotically assisted unicompartmental arthroplasty

Abstract: Robotic-assisted medial UKA results in accurate prosthesis position. Inaccuracy may be attributed to suboptimal cementing technique.
