Perioperative Complications of Simultaneous versus Staged Unicompartmental Knee Arthroplasty

The Patient’s Age and American Society of Anesthesiologists Status Are Reasonable Criteria for Deciding Whether to Perform Same-Day Bilateral TKA

“…However, the type of TKA, such as SD BTKA or St BTKA, was not identified as a risk factor in this study cohort of patients for whom the type of TKA was chosen based on age and ASA classification. Our findings agree with those of several previous studies reporting that an increased risk for postoperative complications was associated with ASA score of 3 or 4, preoperative cardiovascular disease, and older age [8,15,18,24,[29][30][31][32][33][34][35][36][37]. Our data, together with the data of these previous studies, suggest that if patients are properly selected, the type of BTKA procedure, such as SD BTKA and St BTKA, may not increase the risk of postoperative complications and has a risk comparable to the risk of UTKA.…”

Outcome of unicompartmental knee arthroplasty in octogenarians with tricompartmental osteoarthritis: A longer followup of previously published report

“…This risk can be mitigated by the relatively less morbid17 UKA procedure. This has been found to be true in our study as well wherein the surgical perioperative complication rate was 1.8% (1/55), and is substantiated by similar negligible rates seen in larger studies on simultaneous bilateral27 UKA. Studies comparing UKA and TKA for TCOA in very elderly low-demand patients have proven that UKA can provide similar results, with reduced morbidity 252728…”

“…These include early restoration of and near-complete knee ROM17 (possibly due to maintenance of the suprapatellar space), preservation of the knee biology (bone stock, kinematics,58 proprioception, and function), lower morbidity33 (lesser blood loss, shorter hospital stay, lower risk of fat embolism or DVT), and early recuperation2527 (smaller incision, minimal tissue trauma, fewer complications). Further, unlike in an osteotomy, conversion to TKA at any stage (during surgery or in the followup) is technically relatively easier, with eventual outcomes matching those following primary TKA 1534.…”

Unicompartmental knee arthroplasty is effective: ten year results

“…Many authors have reported similar ten year survivorship rates between UKA and TKA, but many others different rates [7,10,23,24]. In this study, a TKA control group was not presented, as the authors believe that indications to perform UKA or TKA could be quite different.…”

“…Additionally, candidates to UKA often present different demographics (younger and less obese), pre-operative (and t h e r e f o r e p o s t o p e r a t i v e ) h i g h e r c l i n i c a l s c o r e s (unicompartmental degeneration and intact ligaments) and distinct functional requests [9], which may create substantial bias. Recent important reports [7,10,23] have shown how patients with UKA had higher pre-and postoperative scores than patients with TKA, whereas changes in scores were similar in both groups. Moreover, functional scores were significantly better in UKA until the three year follow-up, confirming our observed trend that patients with UKA reached the highest IKS score and ROM values very early postoperatively.…”
