Number of repetitions to maximum in hop tests in patients with anterior cruciate ligament injury.

The unilateral horizontal, triple cross-over and vertical hops are commonly used as outcome measures after knee injury but there is little knowledge of the number of repetitions needed to reach maximum performance. Seventy subjects who had either an anterior cruciate ligament deficient or reconstructed knee participated in this study. Unilateral vertical, horizontal, and triple cross-over hop testing was applied to each leg until two consecutive decrements in performance occurred. The number of repetitions to reach maximum during these tests were calculated. Fifteen repetitions of the horizontal and vertical hops, and 10 repetitions of the triple-crossover hop enable distances to be achieved that are acceptably close to maximal levels in these knee-injured patients. In order to increase the likelihood of finding a patient's maximum hop performance after knee injury, more repetitions are suggested than has been reported in the literature.

Validation of the Hughston Clinic subjective knee questionnaire using gait analysis.

INTRODUCTION: Subjective questionnaires, completed by the patient, are often used to document the status of a disabled knee. The purpose of this study was to validate the Hughston Clinic subjective knee questionnaire by describing how knee kinematics and kinetics correlated to subjective knee scores after knee injury and surgery. METHODS: Five groups were studied: patients 2 (N = 37), 6 (N = 37), and 24 (N = 8) wk after ACL reconstruction (ACLR); patients with a chronic PCL deficiency (N = 9); and uninjured controls (N = 8). A three-dimensional motion analysis system and force platform were used to measure flexion angles and knee moments during level walking and stair climbing. RESULTS: Hughston Clinic questionnaire scores were significantly correlated to mechanical descriptors measured during stair ascent and descent in the 2- and 6-wk ACLR groups (P < 0.05). The Hughston Clinic questionnaire score was correlated to several kinematic variables in the ACL reconstructed knee at 24 wk postoperative, e.g., knee flexion during walking. In the PCL deficient group, the Hughston Clinic questionnaire score was correlated with several kinetic measures, e.g., the peak moment (knee extensors). The Hughston Clinic questionnaire score was not correlated to knee mechanics in the control group. CONCLUSION: The Hughston Clinic questionnaire score has been shown to be valid in this study as it reflects some mechanical descriptors during activities of daily living in the first 6 wk post ACL reconstruction. The questionnaire also provides information on gait modifications by people coping with knee injuries.

Correlates of knee laxity change in early rehabilitation after anterior cruciate ligament reconstruction.

Factors other than ligament graft length (knee ROM, knee swelling, initial knee laxity) may need to be accounted for in interpreting changes in knee laxity during rehabilitation following anterior cruciate ligament reconstruction (ACLR) surgery. Twenty-three patients recovering from ACLR surgery (16 M, 7 F, age mean = 30) were tested at 2 and 6 weeks after ACLR with knee laxity measured using th Knee Signature System arthrometer, passive ROM with a standard goniometer and swelling by measuring knee circumference at the mid-patella level using a cloth measuring tape. Spearman correlation coefficients (in parentheses) were calculated using rankings of the change in the injured minus uninjured knee laxity as the dependent variable and the following independent variables: pre-test injured minus uninjured knee laxity (ranked; -0.457; statistically significant two-tailed P < 0.05); change in injured knee maximum extension relative to the uninjured side (ranked; 0.127); change in injured knee maximum flexion relative to the uninjured side (unranked; -0.073); and change in the injured minus uninjured knee girth (unranked; -0.159). These results indicate that consideration should be given to the patient's knee laxity at the start of intervention when using changes in laxity to guide rehabilitation after ACLR.

Mitchell's osteotomy using internal fixation and early mobilisation.

We present the results of a prospective trial of osteotomy of the metatarsal neck for hallux valgus in 31 feet of 23 women, using a new stapling device with no plaster splintage and early weight-bearing. Surgery was performed for pain (29 feet) and difficulty with footwear (nine feet). The average time for return to light work was 3.3 weeks, and to full work 8.3 weeks after operation. Seventeen patients had full recovery within three months and 21 of the 23 patients had complete relief of pain. Shoes were more comfortable in 17 feet and 9 patients could wear narrower shoes. Only two patients were unsatisfied with the appearance of the foot. All the osteotomies united, and the average hallux valgus angle was improved on radiographs from 35 degrees to 23 degrees. The mean first metatarsal angle was reduced from 16 degrees to 11 degrees. The new technique allows more accurate surgery and easier postoperative management.

Replacement of the first metatarsophalangeal joint with a silicone elastomer ball-shaped spacer.

We report the use of a silicone elastomer ball-shaped spacer for the treatment of hallux valgus and hallux rigidus. One hundred and eleven operations were performed in 77 patients over a 5-year period. The best results were obtained in patients with hallux rigidus. Good results were obtained in hallux valgus, but it was found that in patients with severe preoperative deformity the correction obtained was inadequate, and an additional procedure would be required for full correction. There were no cases of silicone synovitis.

Failed surgery for recurrent anterior dislocation of the shoulder. Causes and management.

We have reviewed 36 patients who had recurrent anterior dislocation of the shoulder after a previous anterior repair and analysed the various causes of failure. It was found that failure could have been avoided in virtually all of the patients by correct pre-operative diagnosis, selection of the appropriate operation and its proper execution. The further management of these patients is described and suggestions are made as to means of reducing the incidence of failure after primary operation.

Early mobilisation of Colles' fractures. A prospective trial.

The results of a prospective controlled trial of early mobilisation of Colles' fractures in the elderly are presented. Early mobilisation produced less pain and a stronger grip. It did not lead to any greater loss of reduction of the fracture. However, there was no significant improvement in the final range of movement of the wrist. Immobilisation of the wrist for six weeks in plaster is extremely inconvenient for the elderly living alone and the patients greatly appreciated the reduction of this period of time to a minimum.
