“…Its indications have since been expanded based on promising results in various recent studies. Accordingly, the incidence of UKA is also increasing in relatively young less than 60-year-old patients 1 – 6) . However, UKA in young patients is a challenging procedure due to their high expectation on postoperative knee function and long life expectancy, and there is a concern that they are exposed to a higher risk of revision 3 , 6 , 7) .…”

PurposeTo evaluate the long-term clinical results and survivorship of unicompartmental knee arthroplasty (UKA) in patients younger than 60 years of age.Materials and MethodsOne hundred and six cases of medial UKA with a minimum follow-up of 10 years were selected for this study. There were 80 patients and the preoperative diagnosis was osteoarthritis in all cases. The mean age of the patients was 54.2 years and the mean duration of follow-up was 12.1 years. Clinical assessments were performed using the Knee Society clinical rating system, and a survival analysis was performed using the Kaplan-Meier method.ResultsThe mean knee and function scores improved from 52.8±8.4 points and 56.6±10.6 points preoperatively to 85.4±9.1 points and 84.7±10.4 points at the last follow-up, respectively (p<0.001). The mean range of motion was recovered from 130.7° to 132.8° at the last follow-up. Complications occurred in 20 cases (16.7%) and the most prevalent complication was mobile bearing dislocation (n=9, 7.5%). The 10-year survival rate was 92.8% when conversion to total knee arthroplasty was defined as failure, whereas 89.3% when failure was defined as all revision surgeries.ConclusionsThe long-term clinical results of UKA were satisfactory in patients under 60 years of age. Therefore, UKA could be a useful method for the treatment of medial compartment osteoarthritis of the knee in patients younger than 60 years of age.

“…Given enhancements in knowledge and improvements in prosthesis design, UKA has achieved good long-term clinical effects. [24][25][26][27] To improve the accuracy of prosthetic implantation, surgical instruments have been constantly improved, and the navigation system has been clinically applied. 10,12,13 However, clinical applications are dependent on the surgeon's perception and experience in identifying anatomical landmarks, which may be relatively ambiguous and subject to errors.…”

The purpose of this study is to develop and validate a novel patient-specific navigational template for unicompartmental knee arthroplasty (UKA). A total of 120 patients who underwent UKA were randomized and divided into the conventional method and navigational template groups. In the navigational template group, patient-specific navigational templates were designed and used intraoperatively to assist 60 patients with UKA. Information on operation time and blood loss was recorded by an independent operating room nurse. After surgery, the positions of the prostheses were evaluated using X-rays. All navigation templates were found to fit its corresponding biomodel appropriately without any free movement. The navigational template exhibited significantly better accuracy than the conventional method. Statistically significant differences in the femoral prosthesis flip angle, femoral prosthesis flexion angle, and tibial plateau varus and valgus angle were observed between the two groups (p = 0.022, 0.042, 0.043, respectively). In addition, the mean operation time was statistically and significantly lower in the navigational template group than in the conventional group (p = 0.035). This study introduces a novel navigational template to UKA, the accuracy of which is proven by clinical operation. This is a Level III, therapeutic study.

“…As such, its use has been increasing in individuals who play sports, despite limited evidence in this population. 41 , 42 , 43 As with a total joint prosthesis, the unicompartmental prosthesis will also be subject to the injurious effect of excessive axial loads for any sports activities; however, the joint biomechanics are different. The preservation of both cruciate ligaments allows one to retain a large part of the physiological kinematics of the knee and maintain anteroposterior and rotational stability of the native joint, leading to less contact stress in these directions.…”

“… 1 , 4 However, these theories remain to be proven and most orthopedists also apply the sports recommendations for total knee arthroplasty to unicompartmental arthroplasty. 5 , 7 , 37 , 41 Walker et al 42 retrospectively studied 101 patients who underwent medial unicompartmental arthroplasty, with a mean follow-up of 4.4 ± 1.6 years, and found a rate of return to sports practice of 93%, mostly for low-impact sports activities. Specifically, 27% of the patients returned to physical activity in 1 month, 56% returned in 3 months, 77% returned in 6 months, and the remaining 23% needed longer than 6 months or remained inactive.…”

The success of joint replacement surgery has been responsible for raising patients' expectations regarding the procedure. Many of these procedures are currently designed not only to relive the pain caused by arthrosis, but also to enable patients to achieve functional recovery and to engage in some degree of physical activity and sports. However, as physical exercise causes an increase in forces exercised through the articular prosthesis, it can be an important risk factor for its early failure. Scientific literature on sports after arthroplasty is limited to small-scale retrospective studies with short-term follow-up, which are mostly insufficient to evaluate articular prosthesis durability. This article presents a review of the literature on sports in the context of hip, knee, shoulder and intervertebral disc arthroplasty, and puts forward general recommendations based on the current scientific evidence. Systematic Review, Level of Evidence III.
