An anterior cruciate ligament (ACL) injury may be diagnosed by clinical examination and radiological investigation using magnetic resonance imaging or by arthroscopy.1,2Based on our experience, the ACL tear in concomitant chronic ACL and posterior cruciate ligament (PCL) deficient knees may produce knee laxity, which is more difficult to assess on clinical examination, which in turn may affect the management algorithm of the patient. Our hypothesis is that, in a concomitant chronic ACL and PCL injury, posterior capsular contracture and abnormal reattachment of torn ACL will result in less clinical and subjective laxity, preoperatively. The aim of this study is to review a cohort of patients who had undergone PCL reconstructive surgery and compare the preoperative clinical assessments with and without anesthesia with arthroscopic finding of ACL. This is to assess the accuracy and reliability of clinical ACL laxity tests in detecting ACL tear in chronic ACL and PCL injury.
Scrotal tuberculosis (TB) is rare. Lack of awareness may lead to a misdiagnosis and/or delayed diagnosis of scrotal TB. Clinicians should have a high suspicion index for scrotal TB when facing a patient with a chronic scrotal lump. Since scrotal TB can be medically cured, biopsy of the scrotal lump for pathology study and/or urine polymerase chain reaction (PCR) analysis for M. tuberculosis should be performed first for rapid diagnostic purposes, and therefore unnecessary surgery may thereby be circumvented.
AIMS: To evaluate the functional outcomes of a delayed (>6 months post-injury) and combined reconstruction of grade III posterior cruciate ligament (PCL) and grade III posterolateral corner (PLC) deficiencies.
PATIENTS AND METHODS: Between March 2006 and October 2009, a delayed surgery consisting of arthroscopically-assisted PCL reconstruction and open reconstruction of the PLC was performed on 19 men and 2 women (average age, 29 years). The mean time-to-surgery was 18 months (range, 7-51 months) and duration of follow-up was 22 months (range, 12-48 months). Postoperatively, patients were evaluated using Lysholm score, Tegner activity score, and International Knee Documentation Committee (IKDC) subjective and objective scores.
RESULTS: At the final follow-up, majority of the knees (61.9%) achieved either normal or nearly normal rating objective IKDC score. The means of IKDC subjective score, Lysholm score and Tegner activity level were 62.09, 74.35 and 5.14 respectively. One patient was able to participate in competitive sport, 5 patients were able to be involved in recreational sports for at least 5 times per week, 10 patients were able to perform heavy labour and recreational sports for at least twice weekly, 4 patients were able to engage in moderately heavy labour work and one patient was only able to perform light labour work. There was no significant statistical association found between the time-to-surgery and the final patients' outcomes.
CONCLUSIONS: A delayed simultaneous reconstruction of chronic grade III PCL and PLC deficiencies can restore sufficient function for standard daily and recreational sports activities to the patients.
