All patients were male, 4 patients had deficiencies in the right knee, 2 the left knee and the mean patient age was 28.8years (range 17–45). Four CMI were inserted for lateral meniscal deficiencies, two medial. The mean length of implant sutured in place was 41mm (range 35–55). Median pre op scores were KOOS P/S/ADL/QOL 53/100, 54/100, 66/100, 25/100, 44/100, IKDC 49.43%, Tegner 3, SF-36 35.38 PCS and 27.48 MCS and Lysholm 87/100. The mean elapsed time post meniscectomy was 20 months (range 2–51). All but one of the implants used were 9.5mm in width and sizes ranged 35–45mm. At early follow up there have been no complications and background pain has improved in all 6. MIR imaging has shown that none have separated. Post operative follow up suggest improved outcome.
41 patients underwent re-operation at a mean time interval of 21 months (range 2 weeks - 87 months). 79 patients (Group A) had isolated meniscal tears. 44 patients (Group B) had meniscal repair at the same time as elective ACL reconstruction and underwent brace-free, accelerated rehabilitation. 47 patients (Group C) had meniscal repair in association with ACL disruption and underwent staged ligament reconstruction. In Group A, 23 patients underwent re-operation (Indications; meniscal symptoms 21, stiffness 1, infection 1). Nineteen repairs (23.8%) were found to have failed. In Group B, 15 patients underwent re-operation (Indications; meniscal symptoms 12, stiffness 1, revision ACL 2). Twelve (27.2%) repairs were found to have failed. In Group C, Nine (19.6%) repairs were found to have failed. 6 at the time of staged ACL reconstruction and 3 subsequently, at further arthroscopy. There was no statistical difference between the groups with respect to the incidence of failed meniscal repairs. Analysis of possible predictive factors including age, gender, location of lesion and the type of repair did not show statistical significance.
The purpose of this study was to assess the accuracy of a modified version of the pivot shift test in detecting ruptures of the anterior cruciate (ACL) ligament.
The purpose of this study was to investigate the safety and outcome of bilateral simultaneous ACL reconstruction. In patients presenting with an ACL-deficient knee, 2 – 4% have bilateral ACL deficiency. A staged or simultaneous approach can be adopted when the patient requires reconstructive surgery for both knees. We report a case series of 8 patients (6 male, 2 female, average age 30.4 years) who underwent bilateral simultaneous ACL reconstruction. Simultaneous or bilateral ACL reconstruction using ipsilateral patella tendon graft has been reported as a safe procedure with outcome and complication rate no different to unilateral procedures. Considerable cost savings of simultaneous over staged procedures have also been described. There are no case series in the published literature that describe the use of hamstring tendon autograft for bilateral simultaneous ACL reconstruction. We used two camera stack systems and instrument sets to allow for simultaneous bilateral surgery by two surgical teams. Quadrupled hamstring tendon graft was used in 4 patients although in one patient patella tendon graft was used on the second side due to poor quality of hamstring tendons. Patella tendon graft was also used in a further 4 patients. At two weeks all patients were able to discard crutches and were independent in mobility. There was no difference in outcome at one year between those patients undergoing bilateral simultaneous ACL reconstruction in comparison to the outcomes of unilateral ACL reconstruction with respect to Lysholm, Tegner and IKDC scores. The mean follow up period was 2.3 years. Our results demonstrate that bilateral simultaneous ACL reconstruction is safe and cost effective. A simultaneous approach also has the benefit of reducing the overall period of rehabilitation required by the patient. We report good short-term functional outcome but no long-term data is yet available.
The results of the first 20 consecutive patients have been compared with 20 standard TKR procedures. The mean age of 73.5 and BMI of 29 was not significantly different to the standard Group. Mean hospital stay was approximately halved (5 days versus 9 days). 75% of patients were discharged on day 4 without needing extra home support. Mean incision length was 13.5cm and only one of 20 required blood transfusion. Mean operative time was 12 minutes longer and post-operative CT alignment showed no mal-position of the implants.
Questionnaire of surgeons views on photographic records: This showed that less than 50% of surgeons felt they could interpret their own photographs and only 25% felt other surgeons records were useful. 80% felt that single image photographs gave clearer information than 4 small images per sheet. Retrospective audit of 70 arthroscopic records. This showed that the diagnosis was demonstrated in only 60% of records when taken. Small images had been recorded in 75% of cases. Production of guidelines for improving photographic records. Re-audit of 50 subsequent records. This showed a significant improvement such that the diagnosis was clearly demonstrated in 84% of records.
This may lead to a reduction in the need for repeat arthroscopy when patients are referred for second opinions to specialist knee surgeons, thereby reducing costs and morbidity.
100 patients were studied. 3 records were excluded, as there was no follow-up recorded. The demographics on 97 were: mean age 67 (range 37–91), male 56%, mean duration of symptoms 8.8yrs and primary OA in 65%. Overall 43% were improved at 3 months, 31% at 6 months and 29% at 12 months. When the results were analysed according to indication, patients with ‘moderate non-mechanical osteoarthritic symptoms after failed medical management and not severe enough for arthroplasty’ did best (49% at 3 months and 38% at 6 months). Patients with ‘persisting arthritic symptoms after attempted arthroscopic debridement for mechanical type knee symptoms’ had less predictable results (42% improved at 3 months and 23% at 6 months). Patients with ‘severe or deteriorating symptoms while awaiting knee replacement’ or who were ‘too medically ill for TKR’ had a low rate of improvement (18% at 3 months).
We measured the driver reaction times of 40 patients before total knee replacement (TKR) and 4, 6, 8 and 10 weeks after operation. The ability to perform an emergency stop was assessed as the time taken to achieve a brake pressure of 100 N after a visual stimulus. There were 18 drivers and 11 non-drivers; the latter had longer reaction times. In drivers, the ability to transfer the right foot from accelerator to brake pedal did not recover to preoperative levels for eight weeks after right TKR and was unchanged after left TKR. Patients should be advised that they should not drive for at least eight weeks after right TKR.
