Background One of the goals of a TKA is to approximate the function of a normal knee. Preserving the natural ligaments might provide a method of restoring close to normal function. Sacrifice of the ACL is common and practical during a TKA. However, this ligament is functional in more than 60% of patients undergoing a TKA and kinematic studies support the concept of bicruciateretaining (that is, ACL-preserving) TKA; however, relatively few studies have evaluated patients treated with bicruciate-retaining TKA implants. Methods From January 1989 to September 1992, I performed 639 total knee replacements in 537 patients. Of these, 489 were performed in 390 patients using a bicruciate-retaining, minimally constrained device. During the period in question, this knee prosthesis was used for all patients observed intraoperatively to have an intact, functional ACL with between 15°varus and 15°valgus joint deformity. There were 234 women and 156 men with a mean age at surgery of 65 years (range, 42-84 years) and a primary diagnosis of osteoarthritis in 89%. The patella was resurfaced in all knees. The mean followup was 23 years (range, 20-24 years). At the time of this review, 199 (51%) patients had died and 31 (8%) patients were lost to followup, leaving 160 (41%) patients (214 knees) available for review. Component survivorship was determined by competing-risks analysis and Kaplan Meier survivorship analysis with revision for any reason as the primary endpoint. Patients were evaluated every 2 years to assess ROM, joint laxity, knee stability, and to determine American Knee Society scores. Results The Kaplan-Meier survivorship was 89% (95% CI, 82%-93%) at 23 years with revision for any reason as the endpoint. Competing-risks survivorship was 94% (95% CI, 91%%-96 %) at 23 years. At followup, the mean age of the patients was 84 years (range, 63-101 years), the mean flexion was 117°(range, 90°-130°), the mean American Knee Society score improved from a preoperative mean of 42 (range, 26-49) to 91 (range, 61-100; p \ .001). Twenty-two knees in 21 patients (5.6%) were revised, most commonly because of polyethylene wear.

“…The main finding from this review is that X-ray severity of knee OA is a determinant of outcome after TKA. However, it is one, amongst a number, [5][6][7][8][9][10][11] and the strength of association is difficult to predict and remains unanswered. As a result, we cannot provide specific recommendations for ideal timing of TKA.…”

Background Up to 20% of patients are dissatisfied after total knee arthroplasty (TKA). There are many contributing factors. The relationship between preoperative osteoarthritis (OA) severity and outcome post TKA remains unclear. This review explores the relationship between preoperative OA severity with patient reported pain, function and satisfaction post TKA. Methods A pre‐registered systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. Major databases were searched until September 2017. We included studies assessing adults undergoing TKA for OA. Minimum follow‐up was 6 months. Methodological quality assessment was conducted using the Newcastle‐Ottawa Scale. Results Twenty cohort studies with 7478 patients were included. There were 16 good, one fair and three poor quality studies. Knee OA was most commonly reported according to the Kellgren and Lawrence tool. Ten studies showed statistically significant pain outcomes for those with worse preoperative OA. This was supported by meta‐analysis of the Knee Society Score pain change scores to final follow‐up for those with Kellgren and Lawrence grade 4 OA. Six studies showed statistically significant results for various aspect of functional recovery, although meta‐analysis of Knee Society Score function change scores identified no difference. Meta‐analysis of final follow‐up pain and function scores alone yielded no significant difference. Patients with more severe preoperative OA were more likely to be satisfied. There were no studies demonstrating that less severe OA resulted in better pain, function or satisfaction. Conclusion Review of available research indicates that TKA for OA improves pain, function and satisfaction. Those with more severe preoperative radiological knee OA benefit most.

Total knee arthroplasty has been an effective treatment for advanced degenerative joint disease. Traditional knee designs and surgical approaches have resulted in consistently high performance, but some patients may remain dissatisfied after their surgery. Several surgical innovations, including accelerometer-based navigation, patient-specific instrumentation, and robotic-assisted total knee arthroplasty, have been developed to improve the accuracy and precision of total knee arthroplasty surgery, with anticipated secondary benefits of improved functional outcomes and implant survivorship. This article reviews the current status of these technologies as reported in contemporary orthopedic literature. [Orthopedics. 2016; 39(4):217-220.].
