MRI scanning is the establish method of defining intra- and extra-articular diagnoses of patients with non-arthritic knee problems. Discrepancies in reporting have been noted in previous historic studies and anecdotally. The aim of this study was to analyse the reporting of intra-articular pathology and discrepancies in knee MRI reports by two clinician groups, consultant radiologists and consultant knee surgeons in a district hospital setting. A retrospective case-controlled cohort study was conducted using data collected from an outpatient physiotherapy-led knee clinic. Seventy-four patients in the cohort were referred for an MRI scan of their knee(s) following a clinical examination and history. MRI reports from both the consultant knee surgeon and the radiologist were entered into a database with other clinical details. Reports were analysed to determine number of diagnoses and degree of agreement. Each report was deemed to either completely agree, completely disagree or partially agree.Abstract
Introduction
Methods
Cognitive dysfunction has been well documented following total knee replacement. Possible causes that have been postulated include cerebral emboli, post-operative complications and pain. The aim of this study is to compare cognitive decline in patients undergoing conventional total knee replacement (TKR), navigated total knee replacement and total hip replacement (THR). We prospectively analysed 75 patients undergoing lower limb arthroplasty. Group 1 consisted of 25 conventional TKR’s, group 2 consisted of 25 navigated TKR’s and group 3 consisted of 25 THR’s. Cognitive function was assessed by 11 validated neuropsychological tests preoperatively, at 1 week post-operatively and at 6 months post-operatively. Testing was carried out by a clinical psychologist. At day 6 post-operatively 55% of group 1, 83% of group 2 and 61% of group 3 patients had a significant cognitive decline. Group 2 had a significantly greater cognitive decline at day 6 compared to the other 2 groups. At 6 months significant cognitive decline was found in all 3 groups to 21%, 16% and 34% respectively. Group 2 demonstrated the greatest improvement in cognition from day 6 to 6 months post-operatively Significant cognitive decline occurs in two-thirds (66%) of all patients undergoing lower limb arthroplasty at day 6 and remains significant in a quarter (25%) of patients at 6 months. There was no significant difference in cognitive decline in patients undergoing hip and knee arthroplasty.
We report the results of 60 consecutive primary anterior cruciate ligament (ACL) reconstructions performed by a single operator at King’s College Hospital Day surgery unit. A “3 in 1” nerve block was used after general anaesthesia. Semitendinosis and gracilis were harvested from the ipsilateral side, doubled and implanted arthroscopically. Patients were discharged the same day with oral analgesia. The mean age was 34.7 years old (range 18–58). Mean period between injury and reconstruction was 26.9 months (range 6–63 months). Mean follow-up was 38 months (range 7–86 months). Average post operative pain score was 3.86 with an average analgesic requirement of 11.2 days (range 0–50 days) Mean Modified Lysholm score was 85.63 (range 31–100) and mean IKDC score was 79.83 (range 37–100). In conclusion we found that following day surgery ACL reconstruction, pain relief was adequate in most cases, functional outcome was rated good or excellent by 78% of patients and 91% were satisfied with the overall service.
Approximately 46,000 total hip replacements are performed in the U.K. annually with a dislocation rate between 2 and 5%. Birmingham hip resurfacing (BHR) is a bone conserving metal on metal prosthesis, designed for young patients with hip arthroses that claims to substantially reduce the problem of dislocation. Derek McMinn has reported a personal series of 1,030 BHR’s with a dislocation rate of 0.001% (1 out of 1,030). We present a consecutive series of 55 BHR’s performed by one consultant between January 1998 and June 2001 with a dislocation rate of 7.3% (4 out of 55). 3 out of 4 dislocations occurred in anatomically abnormal hips (two occurred in a patient with developmental dysplasia of the hips and one with avascular necrosis of the femoral head). In this paper, we discuss the possible causes of dislocation in BHR. We suggest careful patient selection by less experienced surgeons to reduce the risk of dislocation following BHR.
