Acute Post-Traumatic Locked Knee - An Unmasking of a Rare Knee Disorder

@#Locked knees are commonly caused by meniscal tears, floating osteochondral bodies, ruptured anterior cruciate ligament (ACL) stump, or other mechanical origins in the knee. Some locked knees occur spontaneously, while in most cases, by a preceding knee trauma. Locked knees are rarely caused by a pathological growth in the knee. More unusually is the occurrence of locked knee caused by a pre-existing pathological entity after a traumatic event. We report a rare case of locking in the knee by a pre-existing knee condition presented only after trauma to the knee. This case emphasizes that locking in the knee can be caused by a pathology that may be asymptomatic until it is revealed by a traumatic event.

The PUTRA Press-fit System as An Alternative Femoral Fixation Technique for Posterior Cruciate Ligament Reconstruction – A Technical Note and Outcome Evaluation

Abstract@#We describe our technique of single-bundle PCL reconstruction using a bony femoral press-fit system. 9 patients underwent PCL reconstruction using our pressfit system. The surgical procedure is described in detail. Post-operatively, 5 patients were available for assessment and review. Four patients gave a final Lysholm score of 92 – 100%. Three patients gave a Hospital for Special Surgery (HSS) score of excellent, one fair and one poor. Two patients gave a reduced Tegner activity score post-operatively while the other three gave a similar score post-operatively. Assessment using KT-1000 revealed four patients with a side-to-side difference of less than 3 mm (average side-to-side difference, 1.87 mm), while one patient exhibited a side-to-side difference of 5.8 mm. We believe that our technique enhances tunnel healing through usage of a bone-plug fixation and provides a cheap alternative for graft fixation on the femoral side in PCL reconstruction.

Arthroscopic Mumford Procedure Utilizing the Anteromedial and Neviaser Portals – A Pilot Cadaveric Study on Neurovascular Structures at Risk

Introduction: Degenerative disorder involving the acromioclavicular joint (ACJ) is quite common especially in the elderly. One of the surgical modalities of treatment of this disorder is the Mumford Procedure. Arthroscopic approach is preferred due to its reduced morbidity and faster post-operative recovery. One method utilizes the anteromedial and Neviaser portals, which allow direct and better visualization of the ACJ from the subacromial space. However, the dangers that may arise from incision and insertion of instruments through these portals are not fully understood. This cadaveric study was carried out to investigate the dangers that can arise from utilization of these portals and which structures are at risk during this procedure. Materials and Methods: Arthroscopic Mumford procedures were performed on 5 cadaver shoulders by a single surgeon utilizing the anteromedial and Neviaser portals. After marking each portals with methylene blue, dissection of nearby structures were carried out immediately after each procedure was completed. Important structures (subclavian artery as well as brachial plexus and its branches) were identified and the nearest measurements were made from each portal edges to these structures. Results: The anteromedial portal was noted to be closest to the suprascapular nerve (SSN) at 2.91 cm, while the Neviaser portal was noted to be closest also to the SSN at 1.60 cm. The suprascapular nerve was the structure most at risk during the Mumford procedure. The anteromedial portal was noted to be the most risky portal to utilize compared to the Neviaser portal. Conclusion: Extra precaution needs to be given to the anteromedial portal while performing an arthroscopic distal clavicle resection in view of the risk of injuring the suprascapular nerve of the affected limb.
