The management of symptomatic single bundle Anterior Cruciate Ligament (ACL) ruptures is still a surgical dilemma. Preservation of the intact fibres of the ACL bundle is considered to be a possible source of reinnervation of the ACL autograft which reflects on better proprioceptive knee control after major ligament reconstruction. Results of a prospective study of 67 patients who had a double stranded but single bundle Anterior Cruciate Ligament (ACL) reconstruction for partial ACL ruptures are presented. There were 43 males and 24 females in this study with a mean age at the time of injury of twenty-five years (14 – 40). Eight played sport professionally and thirty-four played at a competitive level. A valgus twisting force was the most common mechanism of injury. Mean injury to operation time was 7.5 weeks (2–12). All procedures were done arthroscopically without using tourniquet, but using an arthroscopy pump and irrigation fluid containing adrenaline. The semitendinosis hamstring graft was used in all reconstructions. The mean follow-up period was 3.3 years (2–5.4). There was one major complication, who developed a reflex sympathetic dystrophy following a saphenous nerve neuroma. The Quality of Life (QOL) score was assessed using the Mohtadi index. The mean pre-operative QOL score of 30 (13–50) was improved to 93 (70–100) post-operatively. Fifty patients were able to return to their previous sporting level at a mean duration of 9 months (6–12).

Preservation of mechanoreceptors by performing a double stranded, single bundle ACL reconstruction in partial ACL ruptures in high demand patients yields good results and enables early return to high demand sports.

The histological findings from the heads of femur or bone biopsy taken from 90 patients with suspected pathological fractures of the femoral neck were studied to determine the rates of significant abnormal pathological findings.The mean age at the time of fracture was 80.41 years (44–99). 29 patients were males and 71 females. The patients were divided into four groups. Group I: 34 patients with fracture without history of fall or trauma. Group II: 21 patients with suspicious radiology of pelvis. Group III: 27 patients with past history of malignancy without known bone metastases. Group IV: 8 patients with past history of malignancy and known bone metastases

None of the patients in groups I and II had significant abnormalities other than osteoporosis. 4 patients (15%) in group III had metastases and 6 patients (75%) in group IV had metastases on histological examination.

We conclude that the absence of history of fall or trauma or subtle radiographic findings in patients with fracture of the neck of the femur is usually not associated with sinister pathology and the cause of fracture in these patients is often osteoporosis. Patients with previous history of malignancy without known bone metastases have a 15% risk of finding of metastatic disease even in the absence of radiological abnormalities. Patients with fractured neck of femur with past history of malignancy and who are known to have bone metastases must be considered as having pathological fractures through metastatic disease until unless proven otherwise
