Purpose: To determine if it is necessary to assess instability of the chronic anterior cruciate ligament deficient knee under general anaesthesia.

Materials and methods: 27 anterior cruciate ligament deficient knees in 27 patients were evaluated both subjectively using the Lachmanns and pivot shift test and objectively using the KT 1000 arthometer. This was done in the preoperative clinic (without the patient anaesthetised) and subsequently in the anaesthetic room with the patient anaesthetised (under general anaesthesia) prior to anterior cruciate ligament reconstruction. The data was prospectively collected. Only data on 21 knees was available for analysis. There were 20 females and one male with an average age of 29 years.

Results: There was no statistical significant difference (using students T test) between the data collected using the KT 1000 arthometer with and without the patient anaesthetised.

A significant difference was noted both for the Lachmanns (p< 0.01) and pivot shift test (p< 0.001) between the results obtained with and without anaesthesia. This however did not change the management.

Conclusion: Assessing the chronic anterior cruciate ligament deficient knee using the KT 1000 arthrometer, Lachmann and pivot shift test under general anaesthesia is not necessary if these assessments have been carried out in clinic.

We designed an experimental study to prove the existence of the popliteofibular ligament (PFL) and to define its role in providing static stability of the knee. We also examined the contribution of the lateral collateral ligament (LCL).

We found this ligament to be present in all eight human cadaver knees examined. These specimens were mounted on a specially designed rig and subjected to posterior, varus and external rotational forces. We used the technique of selective sectioning of ligaments and measured the displacement with a constant force applied, before and after its division. We recorded the displacement in primary posterior translation, coupled external rotation, primary varus angulation and primary external rotation. Statistical analysis using the standard error of the mean by plotting 95% confidence intervals, was used to evaluate the results.

The PFL had a significant role in preventing excessive posterior translation and varus angulation, and in restricting excessive primary and coupled external rotation. Isolated section of the belly of popliteus did not cause significant posterolateral instability of the knee. The LCL was also seen to act as a primary restraint against varus angulation and secondary restraint against external rotation and posterior displacement. Our findings showed that in knees with isolated disruption of the PFL stability was restored when it was reconstructed. However in knees in which the LCL was also disrupted, isolated reconstruction of the PFL did not restore stability.

A 35-year-old man was seen with pain in the back of the knee. MRI showed a mass in the anterior cruciate ligament. Biopsy indicated mucoid degeneration. Arthroscopic resection of the ligament was carried out, with relief of symptoms.

We made a prospective study of 111 children with acute hip pain to assess whether ultrasound can replace traditional radiography. An effusion was diagnosed in 71% by ultrasound but in only 15% by radiography. This effusion persisted for a mean of nine days; symptoms lasted for five days. Two patients found to have Perthes' disease had longer-lasting effusion and symptoms. Patients without an effusion had no obvious cause for their pain, so the pressure of an effusion from a transient synovitis does not account for all patients with irritable hips. Patients with an effusion persisting for over 24 days (the mean + 2 s.d. of our series) had more symptoms, a significantly larger effusion and greater limitation of movement. They may be more at risk for avascular necrosis. We found that radiographic examination influenced the immediate management of only two patients, those with Perthes' disease. We therefore propose a protocol of management for irritable hip, using ultrasonography at the first presentation of certain categories of patients. This would reduce the number of early radiographs by 75%.

We studied nine patients with Paget's disease affecting the skull or facial bones, who were subsequently treated with either dichloromethylene diphosphonate (clodronate) or ethylene-1-hydroxy-1,1-diphosphonate (etidronate). Long-term treatment induced a clinical and biochemical improvement in eight, and this was associated with a reduction in maxillary or skull volume as assessed by quantitative stereophotogrammetry. The one patient whose disease was resistant to treatment with diphosphonate, showed no change in maxillary shape. These studies suggest that the long-term control of disease activity attained with diphosphonates, results in the improvement of skeletal deformity.

In a prospective study of the measurement of osteoporosis in patients with fracture of the femoral neck, we compared a histological with a radiological method. We found no significant correlation between histological planimetry and the radiological six metacarpal hand index in patients with either cervical or trochanteric fractures. This demonstrates that metacarpal morphometry cannot predict histological osteoporosis of the iliac crest.
