“…even state that “we do not recommend the use of Oxford UKA surgery commonly in the treatment of medial compartment osteoarthritis” (page 239) and Schroer et al . that “The unacceptable rate of failure with the Oxford knee implant has led the principal investigator to discontinue its use in practice” (page 3538) 16, 17 . In the present study, we also found that the revision rate of the UKA group was higher than that of the OWHTO group, even though the two groups had similar outcomes and function recovery, and UKA showed a potential superiority in ERAS.…”

“…However, the outcomes of UKA vary in different reports. Crawford's report found that activity level does not affect survivorship of unicondylar knee arthroplasty, 15 while Sever's report showed that UKA had higher early‐stage aseptic revision rates than TKA 16 . Furthermore, in Schroer's research, UKA is deemed a complete failure due to the unacceptably high revision rate, which led the author to refuse to use it anymore 17 .…”

Objective To evaluate the therapeutic effects and revision cases of unicompartmental knee arthroplasty (UKA) and open wedge high tibial osteotomy (OWHTO) in treating medial knee osteoarthritis (MKOA) in patients under 60 years. Methods The present retrospective study included a total of 192 patients who were diagnosed with MKOA and treated by UKA or OWHTO in the Second Affiliated hospital of Xi'an Jiaotong University and Xi'an Honghui Hospital between December 2012 and December 2016. Among these patients, 83 were treated by UKA (17 men and 66 women, aged 53.7 ± 5.2 years) and 109 were treated by OWHTO (23 men and 86 women, aged 51.8 ± 6.9 years). Patients were followed up at 1, 3, 6, and 12 months for the first year postoperation, and every 6 months from the second year postoperation. Basic data, perioperative data, hospital for special surgery (HSS) score, visual analogue pain score (VAS), low‐impact recovery, and revision cases of the patients were evaluated. Results The average follow‐up periods of the UKA group and the OWHTO group were 39.3 ± 11.2 months and 40.2 ± 13.5 months, respectively. No significant difference was found in the basic data of the two groups (P ≥ 0.05). The operative time, incision length, and dominant blood loss of the UKA group was less than those of OWHTO group by 19.6%, 10.7%, and 35.1%, respectively, and the differences were significant (P < 0.05), while no significant difference was found in postoperative in‐bed time (P ≥ 0.05). The HSS scores of the UKA group at 1 and 3 months postoperation were higher than those of the OWHTO group by 5.1% and 3.9% (P < 0.05), while no differences were found from 6 months postoperation (P ≥ 0.05). The VAS score of the UKA group 1 month postoperation was lower than that of the OWHTO group by 12.2% (P < 0.05), while no differences were found from 3 months postoperation (P ≥ 0.05). One year after the operation, most patients in both groups could not achieve ideal recovery in low‐impact sports, and no significant differences were found (P < 0.05). The sport in which most patients could not achieve ideal recovery was mountain climbing. No revision cases occurred in the OWHTO group, while two revisions occurred in the UKA group. Conclusion Candidates for UKA should be chosen carefully and the current indications and contraindications raised by Goodfellow should be modified.

“…Due to the demands to improve life and health conditions of patients with osteoarthritis (OA), minimally invasive surgeries have been favorable to obtain satisfactory results when performing knee arthroplasty. [ 1 ] Rapid recovery surgical protocols are evidence-based multidisciplinary approaches targeted on multimodal patient care and primarily focused on enhancing functional recovery of patients. These protocols include patient education to cope with anxiety and stress of surgery, nutritional planning and avoidance of long hours of fasting, preemptive analgesia, avoidance of tourniquet use, rational antibiotic prophylaxis, local infiltration anesthesia, and early physical therapy modalities.…”

Does mini-midvastus approach have an advantageous effect on rapid recovery protocols over medial parapatellar approach in total knee arthroplasty?

“…

There is an ongoing debate on whether unicompartmental knee arthroplasty (UKA) or total knee arthroplasty (TKA) for end-stage medial osteoarthritis (OA) provides better functional outcomes. [1] The main findings of a recent meta-analysis showed a shorter survival time for UKA, but better clinical and functional performance scores, compared to TKA. [2] However, other reviews have reported no statistically significant difference in the postoperative knee scores.

Unicompartmental knee arthroplasty results in a better gait pattern than total knee arthroplasty: Gait analysis with a smartphone application

Objectives The aim of this study was to compare the smartphone- based gait analysis data of patients who underwent total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA). Patients and methods Between January 2016 and April 2019, a total of 51 patients (3 males, 48 females; mean age: 60.92 years; range, 51 to 70 years) who were operated with UKA or TKA in our clinic were retrospectively analyzed. The patients were divided into two groups according to the type of procedure as the UKA group (n=17) and unilateral TKA group (n=34). Gait analysis was made via a smartphone application (Gait Analyzer software version 0.9.95.0) with data acquired from the accelerometer of the smartphone. This analysis was performed using data collected from the Acceleration Sensor LSM6DSO into the Samsung Galaxy Note 10 Plus phone. Gait velocity, step time, step length, cadence, step time symmetry, step length symmetry, and vertical COM (vert-COM) parameters were measured. Results There were no statistically significant differences between the groups in respect of age, sex, body mass index, operated side, and follow-up duration. Compared to the TKA group, the UKA patients showed a better gait pattern in gait velocity (p=0.03), step time symmetry (p=0.005), and step length symmetry (p=0.024). No significant difference was detected in step time (p=0.807), step length (p=0.302), cadence (p=0.727) and vert-COM parameters (p=0.608). Conclusion The gait of UKA patients is closer to the physiological pattern with a better gait velocity, step time symmetry, and step length symmetry than TKA patients. The surgical treatment option of UKA for knee medial compartment osteoarthritis leads to a better gait pattern than TKA.
