Enhanced recovery after surgery day surgery for MAKO® robotic-arm assisted TKA; better outcome for patients, improved efficiency for hospitals.

Introduction: Robotic-assisted Total Knee Arthroplasty (TKA) was designed to improve implant position accuracy by providing surgeons with real-time intra-operative data to tailor the operation to the patient. Proponents of robotic-assisted TKA believe that this translates into meaningful improvements in outcomes. However, there are concerns that the longer surgical duration associated with robotic-assisted TKA leads to longer length of stay (LOS). In this study, the authors investigated the outcome of MAKO® Robotic-arm Assisted TKA combined with ERAS protocol to assess its effect on LOS and short-term outcomes. Methods: All patients who had undergone unilateral MAKO® ERAS Day Surgery TKA from August 2020 to July 2021 were prospectively followed up and matched to patients who underwent conventional ERAS Day Surgery TKA in the same time period. Factors such as surgical duration, LOS, immediate reduction in pain, 30-days complications, and 6-month PROMs and knee ROM were compared between the two groups. Results: 42 patients underwent MAKO® ERAS Day surgery TKA and were matched to 42 patients who underwent conventional ERAS Day surgery TKA. The study found that despite the longer surgical duration, LOS was comparable between both groups (1.1 ± 0.9days in the MAKO® group vs 1.0 ± 0.3days in the conventional group, p = 0.755) with successful 24-hour discharge in 88.1 % of patients in the MAKO® group. The MAKO® group achieved significantly better ROM compared to the conventional group 6-months post operatively. Post-operative PROMs were comparable between both groups. Conclusion: ERAS Day Surgery protocol can significantly reduce the LOS of patient undergoing MAKO® Robotic-arm Assisted TKA, conferring cost savings and making it a valid option for patients.

Enhanced recovery after day surgery total knee arthroplasty, the new standard of care: An Asian perspective.

BACKGROUND: This study describes the implementation of Enhanced Recovery After Surgery (ERAS) total knee arthroplasty (TKA) with day-surgery protocol to assess the outcome of ERAS day surgery TKA compared with traditional ERAS inpatient TKA in terms of length of stay (LOS), 30-day readmission, complications, and patient-reported outcome measures (PROMs). METHODS: Patients who underwent unilateral primary TKA from August 2020 to July 2021 were followed up. All TKAs were performed with the ERAS protocol. Patients who fulfilled the following inclusion criteria were offered day-surgery protocol: (1) ASA ≤ 3; (2) agreeable for discharge home. In addition, this day-surgery protocol comprised the following: (i) on-call physiotherapy review; (ii) home visit by physiotherapist at 1 week postoperative; (iii) home visit by nurse at 2 weeks postoperative. Day surgery was defined as discharge within 24 h. Patients were followed up for 6 months and PROMs, postoperative complications, and re-admissions recorded. RESULTS: A total of 738 patients were included (342 ERAS day surgery, 396 ERAS inpatient). 92.4% of patients in the day-surgery group were successfully discharged within 24 h, leading to a shorter mean LOS of 1.13 days compared with 4.12 days in the inpatient group (P < 0.005). Both groups achieved significant and comparable improvement in Knee Society Score, Oxford Knee Score, and Physical and Mental component of Short Form-36. Both groups had similar rate of 30-day readmission and complications. CONCLUSION: Patients who underwent ERAS day surgery TKA achieved similar functional and quality of life improvement compared with ERAS inpatient TKA with no increased complication rate. ERAS day surgery TKA is safe and cost effective, and its use should be promoted.

Polymetatarsia of the Foot without Polydactyly: A Case Report.

CASE: We report a rare case of polymetatarsia without polydactyly. Our patient presented with pain and difficulty with shoewear. Radiographs showed an accessory metatarsal arising from the lateral aspect of the fourth metatarsal proximal metaphysis, fusing distally with the medial aspect of the fifth metatarsal head to form a single metatarsophalangeal joint. He was treated with a chevron osteotomy of the conjoined complex and an Akins osteotomy of the fifth proximal phalanx. Our patient recovered functionally, and his pain improved postoperatively. CONCLUSION: The chevron osteotomy is an option for treating polymetatarsia without polydactyly with the aim of reducing the forefoot width. LEVEL OF EVIDENCE: Case study, level 5.
