“…Compared with total knee arthroplasty (TKA), UKA can provide better physiological function, quicker recovery, shorter hospital stay and fewer perioperative complications, especially in early OA. [4][5][6][7] Recently, the incidence of UKA has increased rapidly worldwide. Through strict case selection, improvement of surgical techniques and improvement of prosthesis design, the long-term efficacy of UKA is now close to or even better than that of TKA.…”

Efficacy and mid/long-term survivorship of mobile-bearing unicompartmental knee arthroplasty for medial compartment knee osteoarthritis combined patellofemoral joint arthritis: a prospective cohort study protocol

IntroductionUnicompartmental knee arthroplasty (UKA) is one of the most effective surgical procedures for treating isolated medial compartment knee osteoarthritis. However, previous studies have regarded patellofemoral osteoarthritis as a contraindication for UKA. In contrast, most current research shows that damage to the articular cartilage of the patellofemoral joint, even to the extent of full-thickness cartilage loss, has no influence on the outcome of UKA.Methods and analysisStudy settings: This study is a prospective cohort study that will compare the Forgotten Joint Score and Lonner patellofemoral joint score of patients who have undergone UKA; the patients will be divided into two groups (with and without patellofemoral joint osteoarthritis (PFJOA)). Primary objective: Long-term follow-up will be used to evaluate the effect of the operation on the above-mentioned scores in both the groups. Secondary objective: We will divide the patients from the with PFJOA group into three subgroups according to the localisation of patellofemoral cartilage lesions (medial zone, lateral zone and central zone). We aim to compare knee joint scores among these groups and clarify the impact of different wear sites on clinical efficacy. We will use CT to explore the potential mechanism through which UKA affects patellofemoral joint-related parameters (lateral patellar tilt, lateral patellar shift and tibia tuberosity-trochlear groove distance). We will also record mid-term/long-term post-surgery complications.Ethics and disseminationThis study’s protocol is in accordance with the Declaration of Helsinki. This study was approved by the Ethics Committee of Xuanwu Hospital. The results of this study will be disseminated in international peer-reviewed journals.Trial registration numberChiCTR2000030310.

“…Unicompartmental knee arthroplasty (UKA) is one of most effective surgical procedures for the treatment of isolated medial compartment osteoarthritis. Compared to total knee arthroplasty (TKA), UKA(including both fixed bearing UKA and mobile bearing UKA) can provide better physiological function, quicker recovery, shorter hospital stay, and fewer perioperative complications, especially for early arthritis [1,2]. Recently, the use of the Oxford UKA has increased rapidly around the world, and the effectiveness and safety of a minimally invasive surgical approach for Oxford UKA has demonstrated good to excellent long-term follow-up [3,4].…”

Background: Oxford Unicompartmental Knee Arthroplasty (UKA) has increased rapidly around the world, and the effectiveness and safety of a minimally invasive surgical approach for it demonstrate excellent outcome. Oxford UKA represents an interesting solution for older patients. The aim of our study is to evaluate the perioperative complications and short-term clinical outcome and analyze the safety for older patients who undergo Oxford UKA.Methods: A retrospective review was performed of all patients who underwent Oxford UKA between June 2015 and January 2018. We divided all patients into three groups (ages 60-69; ages 70-79; age over 80). We used the HSS score and WOMAC score to evaluate the general condition of the patients' knees. We also recorded perioperative complications and long-term complications.Result:60 patients (60 knees) between the ages of 60 and 69 (Group 1), 70 patients (79 knees) between the ages of 70-79 (Group 2) and 65 patients (70 knees) over 80 years old (Group 3) were included in the study. The mean follow-up was 21.34±12.04, 22.08±11.38 and 21.76 ± 10.20 months in Group 1, 2 and 3, respectively. At last follow-up, the patients in Group 3 showed lower function scores as compared to group 1 and 2 (P <0.05), but both the HSS score and the WOMAC score were significantly improved in both groups after surgery. The rate of perioperative complications and other complications in elderly patients is the same as in younger patients. Conclusion:Oxford UKA is an effective and safe treatment for osteoarthritis, even in old adult patients in China. The knee joint pain symptoms of the elderly patients are relieved and the function is improved, but the function is still poor compared with the younger patients.

Background: The use of Oxford Unicompartmental Knee Arthroplasty (UKA) has increased rapidly in both Western and Asian populations, with excellent functional outcomes and high patient satisfaction. While previous evidence regarding clinical outcomes and survival rates after Oxford UKA was based on studies in Western populations, the results may be different in Asian patients. The relevance of age for postoperative function after Oxford UKA also remains unclear. Hence, the aim of our study was to clarify the effectiveness and safety of Oxford UKA in Asian patients aged over 80 years.Methods: A retrospective review was performed and included 195 patients (209 knees) who underwent an Oxford UKA between June 2015 and July 2018. We divided the patients into three groups by age: Group 1, 60-69 years; Group 2, 70-79 years; and Group 3, over 80 years. We used the Hospital for Special Surgery (HSS) score and Western Ontario and McMaster (WOMAC) Universities Osteoarthritis Index score to evaluate the general condition of the patients’ knees before surgery and at last follow-up. We also recorded perioperative and short-term complications.Result: Group 1 consisted of 60 patients (60 knees); Group 2, 70 patients (79 knees); and Group 3, 65 patients (70 knees). The mean follow-up was 21.34 ± 12.04, 22.08 ± 11.38, and 21.76 ± 10.20 months in groups 1, 2, and 3, respectively. At last follow-up, the patients in Group 3 showed lower function scores compared to groups 1 and 2 (P <0.05), but the HSS scores and the WOMAC scores were significantly improved in all three groups. In terms of perioperative and other complications, the three age groups did not differ significantly.Conclusion: Oxford UKA is an effective and safe treatment for osteoarthritis, even in elderly patients in China. Elderly patients have lower knee function scores than younger patients. However, the knee joint pain of the elderly patients was relieved and function improved compared to the preoperative condition.
