“…While the long-term successful results of UKA are known in the literature, the importance of patient, surgeon, and implant related factors has been reported (20)(21)(22)(23)(24). In this study, we found similar good clinical, functional, and radiological results, and low revision rates in both designs.…”

“…Even if there is no mechanical or radiological problem in patients with intense pain after UKA, revision surgery (TKA) can be decided quickly (19). UKA tends to be performed on younger and more active patients than TKA, which is why functional comparison of UKA and TKA may be misleading (24). For these reasons, we compared UKA patients among themselves, as MB-UKA versus FB-UKA.…”

Aim: Unicondylar knee arthroplasty (UKA) is among the treatment options for patients with arthritis limited to one compartment of the knee. Fixed-bearing (FB) and mobile-bearing (MB) inserts are present. This study aimed to compare functional and clinical outcomes and revision rates of patients operated with FB-UKA and MB-UKA. Material and Methods: A total of 131 knees of 118 patients underwent cemented UKA, with a mean follow-up period of 80.58±31.31 months for FB-UKA and 97.66±29.24 months for MB-UKA. Clinical and functional evaluation was performed by the Knee Society Score (KSS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) score, at the last follow-up visit. The factors affecting the radiological and functional results, complication, and revision rates were examined under three main titles; i) surgeon-related, ii) patient-related, and iii) component alignment-related factors. Results: There was no significant difference between the groups in terms of age, gender, body mass index, and side. Regarding the KSS scores, 9 (6.87%) knees were within acceptable limits, 62 (47.32%) knees were found to be good, and 60 (45.80%) knees were found to be excellent. No statistically significant difference was found between groups (p=0.497). Regarding the WOMAC scores, the MB-UKA group had significantly lower pain (p=0.049) and stiffness (p=0.014), but similar functional (p=0.591) scores. There was no statistically significant difference regarding revision rates (p=0.931). Conclusion: Similar clinical, functional, and radiological results and low revision rates were found. In terms of pain and joint stiffness, a significant difference was found between groups, in favor of MB-UKA.

“…Thompson et al[14] conducted a retrospective study including 229 knees and found that younger patients had better results than older patients and body mass index (BMI) had no direct association with failure rate. It is justified to broaden classic UKA indications owing to the study performed by von Knoch et al[15]. The main reasons for failure in UKA includes the defects on prosthesis design, a lack of experience in surgical techniques, the progression of arthritis, and inadequate patient selection[16].…”

BACKGROUNDKnee osteoarthritis is the most prevalent form of osteoarthritis and is becoming the main reason for progressive pain in knee joints. Arthroscopy combined with unicondylar knee arthroplasty (UKA) is one of the effective methods for the treatment of severe unicompartmental knee arthritis. This surgical approach gives us the capacity to explore all the articular cavities and plays a vital role in UKA patient selection. However, some scholars think that the surgical procedure is traumatic and may increase the rate of surgical infection, and its clinical efficacy needs further study.AIMTo compare the clinical effect of arthroscopy combined with UKA and UKA alone for patients suffering from unicompartmental osteoarthritis (OA).METHODSA retrospective study was conducted on patients who were diagnosed with unicompartmental OA (Kellgren–Laurence grade ≥ III) and underwent UKA between October 2012 and November 2006. The patients were followed at 3, 6, and 12 mo and every 2 years thereafter. During each follow-up, the radiographic materials, the range of motion of knee and hospital for special surgery (HSS) score, knee society score and knee function score as recorded, and the modes and time of failure and revision details were collected as well.RESULTSData on 104 patients (118 knees), including 54 patients (60 knees) in the arthroscopy combined with UKA group (group A) and 51 (58 knees) in UKA alone group (group B) were collected during an average follow-up duration of 7.25 years, excluding the cases who were lost to follow-up. At the final follow-up, 3 (5.0%) of 60 knees in group A compared with 4 (6.9%) of 58 knees in group B failed and converted to total knee arthroplasty, with no statistically significant difference between the two groups (P = 0.933). The percentage of patients receiving blood transfusion was 40% in group A, significantly lower than that in group B (67.2%; P = 0.003). Total volume of blood transfusion in group A was also significantly lower than that of group B (P = 0.001). Both groups improved significantly after operation in clinical symptoms and functions. HSS score, knee society score, and knee function score increased significantly at the latest follow-up compared to pre-operation in group A, from 59.6 ± 10.9 to 82.7 ± 9.3 (mean difference [MD], 23.2; 95%CI: 19.3-27.0; P = 0.000), 47.3 ± 6.3 to 76.2 ± 13.1 (MD, 28.9; 95%CI: 25.1-32.7; P = 0.000), and 57.5 ± 6.3 to 75.1 ± 19.6 (MD, 17.5; 95% CI: 12.1-23.0; P = 0.000); and in group B, from 59.3 ± 15.6 to 84.3 ± 10.1 (MD, 23.7; 95%CI: 18.9-28.5; P = 0.000), 49.1 ± 9.2 to 75.1 ± 13.2 (MD, 24.7; 95%CI: 19.9-29.5; P = 0.000), and 59.3 ± 9.0 to 77.4 ± 13.8 (MD, 17.2; 95%CI: 12.8-21.6; P = 0.000).CONCLUSIONArthroscopy combined with UKA and UKA alone both provide benefits in clinical symptom improvement and alignment correction. Arthroscopy combined with UKA does not increase the infection probability and surgical complications, and has an advantage in reducing the total volume of blood transfusion and the percentage of patients receiving blood t...

This article describes the rationale and the surgical technique of patient-specific uni-, bi-, or three-compartmental knee arthroplasty using the second generation (G2) of ConforMIS™ technology. The patient-individual implants and instruments are designed and fabricated based on data from a preoperative computed tomography of the lower limb. The disposable patient-specific drill guides and cutting-jigs are manufactured under consideration of the anatomical and biomechanical axes of the knee joint and mediate efficient pre-navigation of the saw-cuts on the femoral and tibial bone without the need for an additional navigation or balancing device. The surgical technique for all types of knee resurfacement comprises the steps of cartilage removal, knee balancing in extension and flexion, sparing bony cuts, final preparation of femur and tibia, trialling, cementing of components and final choice of tibial insert. The use of individualized three-dimensional image-derived resurfacing implants, as well as personalized single-use instrumentation, facilitates the surgeon to perform an almost anatomical knee resurfacement that has the potential to restore almost normal knee kinematics. The limited data on this novel technology is promising, however long-term clinical data is needed for final evaluation of this technology.
