| 1 | Alignment of the hindfoot following total knee arthroplasty: A systematic review显示文摘BACKGROUND There appears to be a close relationship between deformities at the knee joint and at the hindfoot in patients with knee osteoarthritis(OA).Despite this intrinsic link,there is a dearth of studies investigating alterations in hindfoot alignment following total knee arthroplasty(TKA)in patients with knee OA.AIM To evaluate changes in alignment of the hindfoot following TKA,foot and ankle clinical outcomes in terms of subjective clinical scoring tools following surgical intervention,and to analyse the level of evidence(LOE)and quality of evidence(QOE)of the included studies.METHODS MEDLINE,EMBASE and Cochrane Library databases were systematically reviewed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.Studies reporting changes in the postoperative alignment of the hindfoot following TKA were included.The level and QOE were recorded and assessed.RESULTS Eleven studies with a total of 1142 patients(1358 knees)met the inclusion/exclusion criteria.Six studies were of LOE II and 5 studies were of LOE III.Patients with preoperative varus knee deformity and valgus hindfoot deformity demonstrated improvement in hindfoot alignment post TKA.Patients with preoperative varus knee deformity and varus hindfoot deformity demonstrated no improvement in hindfoot alignment following TKA.Twelve different radiographic parameters were used to measure the alignment of the hindfoot across the included studies,with the tibio-calcaneal angle most frequently utilised(27.3%).CONCLUSION This systematic review demonstrated that the hindfoot may display compensatory changes in alignment following TKA in patients with knee OA.However,the marked heterogeneity between the included studies and poor QOE limits any meaningful cross sectional comparisons between studies.Further,well designed studies are necessary to determine the changes and outcomes of hindfoot alignment following TKA. | James J Butler Nathaniel P Mercer Eoghan T Hurley Mohammad T Azam John G Kennedy | 2021 | World Journal of Orthopedics2021，12，10： | 1 |
| 2 | Can bedside needle arthroscopy of the ankle be an accurate option for intra-articular delivery of injectable agents?显示文摘BACKGROUND Bedside needle arthroscopy of the ankle under local anesthesia has been proposed for intra-articular delivery of injectable agents.Accuracy and tolerability of this approach in the clinical setting–including patients with end-stage ankle pathology and/or a history of prior surgery–is not known.AIM To assess clinical accuracy and tolerability of bedside needle arthroscopy as a delivery system for injectable agents into the tibiotalar joint.METHODS This was a prospective study that included adult patients who were scheduled for an injection with hyaluronic acid to the tibiotalar joint.In our center,these injections are used as a last resort prior to extensive surgery.The primary outcome was injection accuracy,which was defined as injecting through the arthroscopic cannula with intra-articular positioning confirmed by a clear arthroscopic view of the joint space.Secondary outcome measures included a patientreported numeric rating scale(NRS,0-10)of pain during the procedure and willingness of patients to return for the same procedure.NRS of ankle pain at rest and during walking was collected at baseline and at 2-wk follow-up.Complications were monitored from inclusion up to a 2-wk control visit.RESULTS We performed 24 inspection-injections.Eleven(46%)participants were male,and mean age was 46.8±14.5 years.Osteoarthritis was the indication for injection in 20(83%)cases,of which 8(33%)patients suffered from osteoarthritis Kellgren-Lawrence grade IV,and 10(42%)patients from Kellgren-Lawrence grade III.An osteochondral defect was the indication for injection in 4(17%)cases.A history of ankle surgery was present in 14(58%)participants and a history of multiple ankle surgeries in 11(46%)participants.It was possible to confirm accuracy in 21(88%)procedures.The 3(12%)participants where needle arthroscopy did not reach a clear view of the joint space all suffered from Kellgren-Lawrence grade IV osteoarthritis.Pain during the procedure was reported with a median of 1[interquartile ranges(IQR):0–2].Willingness to return was 100%.Pain in rest decreased from a median NRS of 4(IQR:2–7)at baseline to a median of 3(IQR:1–5)at follow-up(P<0.01).Pain during walking decreased from a median NRS of 8(IQR:6–9)to a median of 7(IQR:4–8)(P<0.01).Infections or other complications were not encountered.CONCLUSION Clinical accuracy and tolerability of bedside needle arthroscopy of the ankle as a delivery system for injectable agents are excellent.Accuracy was 100%in patients without total ventral joint obliteration. | Tobias Stornebrink Sjoerd A S Stufkens Nathaniel P Mercer John G Kennedy Gino M M J Kerkhoffs | 2022 | World Journal of Orthopedics2022，13，1： | 1 |
