With advances in mobile application, digital health is being increasingly used for remote and personalised care. Patient education, self-management and tele communication is a crucial factor in optimising outcomes. We explore the use of a smartphone app based orthopaedic care management system to deliver personalised surgical experience, monitor patient engagement and functional outcomes of patients undergoing knee arthroplasty.Introduction
Aims
We studied the outcomes following arthroscopic primary repair of bucket handle meniscus tears to determine the incidence of re-tears and the functional outcomes of these patients. Prospective cohort study. Over a 4-year period (2016 to 2020), 35 adult patients presented with a bucket handle tear of the meniscus. Arthroscopic meniscal repair was performed using either the all inside technique or a combination of all-inside and inside-out techniques. 15 patients also underwent simultaneous arthroscopic anterior cruciate ligament reconstruction. Functional knee scores were assessed using IKDC and Lysholm scores.Aims
Methodology
Anterior cruciate ligament (ACL) injuries represent a significant burden of disease to the orthopaedic surgeon and often necessitate surgical reconstruction in the presence of instability. The hamstring graft has traditionally been used to reconstruct the ACL but the quadriceps tendon (QT) graft has gained popularity due to its relatively low donor site morbidity. This is a single centre comparative retrospective analysis of prospectively collected data of patients who had an ACL reconstruction (either with single tendon quadrupled hamstring graft or soft tissue quadriceps tendon graft). All surgeries were performed by a single surgeon using the All-inside technique. For this study, there were 20 patients in each group. All patients received the same post-operative rehabilitation protocol and were added to the National Ligament Registry to monitor their patient related outcome scores (PROM).Introduction
Methods
There has been a significant increase in the demand for arthroplasty as a result of the Covid 19 pandemic and lack of beds on the green pathway. The average length of in-hospital stay following knee replacements has been successfully reduced over the years following introduction and adoption of enhanced recovery protocols. Day case arthroplasty has the potential to be efficient as well as cost-effective. We present our day case pathway for elective knee arthroplasty and early results of its adoption at a district general hospital. Our pathway was developed through a multidisciplinary input from surgeons, anaesthetists, physiotherapists, nursing staff, administrative staff, surgical care practitioners and pharmacists. Inclusion criteria were defined to identify patients suitable for cay case arthroplasty. Results of 32 patients who underwent day case partial and total knee replacement at our institution between 2018 to 2022 are presented. 31 out of 32 (97%) were discharged safely on the day of surgery. Patients were discharged at a mean of 7 hours following surgery. There were no re-admissions following discharge. There were no surgical complications at a mean follow-up of 2 years. Patient feedback revealed high levels of satisfaction and that they would recommend the pathway to others. Cost analysis revealed savings towards bed costs. Our early results demonstrate day case knee arthroplasty to be safe and cost effective. With limited resources to tackle the enormous backlog of arthroplasty, it offers the potential to make theatre utilization efficient.
Anatomic all-inside ACL reconstruction using TransLateral technique is a relatively new technique that reduces surgical invasion and pain leading to early recovery. We evaluated clinical outcomes of patients undergoing primary anatomic all-inside ACL reconstruction using TransLateral technique. Retrospective case-series evaluating patients undergoing surgery from June 2013 – December 2017. Patients were followed up clinically and using PROMS including EQ-5D, KOOS, IKDC and Tegner scores. Paired two-tailed student t-tests were used to assess clinical significance. 138 patients were included (115 males, 23 females). Mean age was 30 years (range 16.0 – 60.2). Graft choice included isolated semitendinosus (n=115) or both semitendinosus and gracilis (n=26). Mean graft length and diameter were 62.1mm and 8.7mm. Sixteen cases (11.3%) returned to theatre; MUA for arthrofibrosis (n=4), infection (n=2), haemarthrosis (n=1) and metalwork failure (n=1). Incidence of graft re-rupture was 5.7% (n=8); 7 cases were in the mid-bundle femoral tunnel placement. 52.5% (n=74) had complete peri-operative PROMS scores. Mean peri-operative EQ-5D VAS scores were 69.8 and 78.2 (p=0.02). Mean peri-operative KOOS scores for all domains demonstrated significant improvements (p<0.001). Mean peri-operative IKDC scores were 46.1 and 72.5 (p<0.05) and peri-operative Tegner activity scores were 3.3 and 5.3 (p<0.001). Anatomic all-inside ACL reconstruction using TransLateral technique demonstrates favourable clinical and biomechanical advantages including independent anatomic femoral tunnel placement, bone preservation and use of single tendon graft. Patients report significant improvements in pain, functional outcome, quality of life and return to sports. Mid-bundle femoral tunnel placement has been abandoned due to higher failure rate.
Patellofemoral Arthroplasty (PFA) prosthesis with asymmetric trochlear component was introduced as an improvement from existing designs for surgical treatment of symptomatic isolated patellofemoral arthritis. The purpose of this study was to evaluate midterm results in patients who underwent PFA procedure using such prosthesis. Our study involved a continuous retrospective cohort of patients who underwent PFA using Journey PFJ with asymmetric trochlear component, performed between June 2007 and October 2018 at a non-designer centre. The Patient Reported Outcome Measures and patient satisfaction questionnaires were collected for final evaluation.Aim
Methods
Medial patellofemoral ligament (MPFL) reconstructions are often performed using gracilis autografts, this can be associated with donor site morbidity and complications. The use of synthetic material can circumvent a harvest operation and have previously been demonstrated to be effective in other types of reconstructive procedures and may be effective in MPFL reconstruction. We report our experience and clinical results with the use of FiberTape (FT) in MPFL reconstruction and compare it to the same surgical technique using standard autografts. Data were collected prospectively in 50 MPFL reconstructions. The first 27 underwent reconstruction using autograft; the following 23 patients were treated with FT. All patients were clinically and radiologically assessed and underwent pre- and post-operative scoring using the Kujala score, Bartlett score, Modified Tegner activity rating scale, SF 12 score and Lysholm score. Statistical significance was tested between groups using ANOVA with repeated measures.Background of study
Materials and Methods
Oxford Medial Unicompartmental Knee Replacement (OMUKR) is a well-established treatment option for isolated medial compartment arthritis, with good patient reported outcome measures (PROMs). We present our results of the Oxford Domed Lateral Unicompartmental Knee Replacement (ODLUKR) to establish if patients benefit as much as with OMUKR. Retrospective review of prospectively collected data of a single surgeon series of consecutive UKR from 2007 to 2014 were collated with a minimum 2 years follow-up. PROMs data were collected using pre- and post-operative Oxford Knee Scores (OKS) (best score of 48). One hundred and twenty-eight OMUKR and 27 ODLUKR were performed in the study period. There was no significant difference in the age at time of surgery, but there were significantly more women in the ODLUKR group (74% vs 53%). There was no significant difference in pre-op OKS between the groups (OMUKR = 16/48; ODLUKR = 20/48), or the improvement in OKS post-op (OMUKR = 19 points; ODLUKR = 17 points). One ODLUKR was revised to Total Knee Replacement (TKR) for pain. There were three (11.1%) bearing dislocations, which were treated with thicker bearing exchange, with no subsequent problems. There were no bearing dislocations in the OMUKR. Four OMUKR were revised to TKR due to pain. The overall implant survivorship was 96.3% for ODLUKR and 96.9% for OMUKR. ODLUKR is a good treatment option for isolated lateral compartment arthritis and gives results equivalent to OMUKR. There is, however, an increased risk of bearing dislocation so should be performed by a high volume UKR surgeon.
Treatment of osteoarthritis is evolving, allowing more options of surgical intervention at an earlier stage. The interpositional knee device is a recently developed patient specific implant used for the treatment of uni-compartmental osteoarthritis. It is designed for use in mild to moderate osteo-arthritis only. The benefits it offers are, that it is less invasive than traditional methods, can be performed as a day procedure and does not limit future options. Young adults with uni-compartmental arthritis are suitable for this implant. A MRI scan of the patient's knee is reviewed by radiologists to decide if the patient is suitable. A bespoke implant, based on the MRI data, is produced. Prior to insertion an arthroscopy is undertaken to allow proper positioning of the implant. We have treated 26 patients with the iForma Conformis interpositional knee implant in South Wales at the Princess of Wales Hospital, Bridgend and the Royal Glamorgan Hospital, Llantrisant since November 2007. The pre- and post-operative WOMAC scores were recorded. Average age was 54.7 years, BMI 32; 9 females and 17 males. The average pre-operative WOMAC score was 42.2 with an improvement to 62.9. 33 implants were used (19 right, 14 left). 7 patients experienced post-operative problems (5 implants removed and 2 MUAs). No dislocations were reported. Average follow-up time was 12.6 months (range 6-26 months). Our early experience suggests patient selection plays a vital role in the outcome of patients following surgery. It indicates that the interpositional knee device is a viable and safe alternative to a uni-compartmental knee replacement.
