What is the role of minimally invasive surgery in a fast track hip and knee replacement pathway?
Minimally invasive hip and knee replacement surgery (MIS) continues to receive coverage in both the popular press and scientific literature. The cited benefits include a smaller scar, less soft tissue trauma, faster recovery, reduced hospital stay, decreased blood loss and reduced post-operative pain. These outcomes are highly desirable and consistent with the aims of fast track hip and knee pathways. This paper evaluates the literature and discusses whether performing MIS over conventional surgical techniques offers advantages in a fast track hip and knee pathway.
An English language literature search was performed using the MEDLINE and PubMed databases. Case series, randomised controlled trials and systematic reviews were included in the review.
The reported improvements in recovery brought about by MIS must be considered multifactorial. In combination with improved clinical pathways, MIS can be associated with quicker recovery and shorter length of hospital stay.
There is insufficient evidence to indicate that surgical technique alone makes a significant difference to recovery or reduces soft tissue trauma. No consensus on whether to use MIS techniques in fast track hip and knee replacement pathways can therefore be drawn. This is especially important given that the complication rates of MIS in the low to medium volume surgeon appear unacceptably high compared with standard approaches. It is also too early to assess the long-term effects of MIS on implant survival.

ABSTRACT: The increasing numbers of patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA), combined with the rapidly growing repertoire of surgical techniques and interventions available have put considerable pressure on surgeons and other healthcare professionals to produce excellent results with early functional recovery and short hospital stays. The current economic climate and the restricted healthcare budgets further necessitate brief hospitalization while minimizing costs.
Clinical pathways and protocols introduced to achieve these goals include a variety of peri-operative interventions to fulfill patient expectations and achieve the desired outcomes.
In this review, we present an evidence-based summary of common interventions available to achieve enhanced recovery, reduce hospital stay, and improve functional outcomes following THA and TKA. It covers pre-operative patient education and nutrition, pre-emptive analgesia, neuromuscular electrical stimulation, pulsed electromagnetic fields, peri-operative rehabilitation, modern wound dressings, standard surgical techniques, minimally invasive surgery, and fast-track arthroplasty units.

ABSTRACT: Minimally invasive total knee replacement (MIS-TKR) has been reported to have better early recovery than conventional TKR. Quadriceps-sparing (QS) TKR is the least invasive MIS procedure, but it is technically demanding with higher reported rates of complications and outliers. This study was designed to compare the early clinical and radiological outcomes of TKR performed by an experienced surgeon using the QS approach with or without navigational assistance (NA), or using a mini-medial parapatellar (MP) approach. In all, 100 patients completed a minimum two-year follow-up: 30 in the NA-QS group, 35 in the QS group, and 35 in the MP group. There were no significant differences in clinical outcome in terms of ability to perform a straight-leg raise at 24 hours (p = 0.700), knee score (p = 0.952), functional score (p = 0.229) and range of movement (p = 0.732) among the groups. The number of outliers for all three radiological parameters of mechanical axis, frontal femoral component alignment and frontal tibial component alignment was significantly lower in the NA-QS group than in the QS group (p = 0.008), but no outlier was found in the MP group. In conclusion, even after the surgeon completed a substantial number of cases before the commencement of this study, the supplementary intra-operative use of computer-assisted navigation with QS-TKR still gave inferior radiological results and longer operating time, with a similar outcome at two years when compared with a MP approach.
