Review Case ReportsSuperior dislocation of the patella with early onset patellofemoral arthritis: a case report and literature review.
Among the traumatic patellar dislocations, superior dislocation of patella without patellar ligament injury is very rare. We present in this article, a case of superior dislocation of the patella trapped by interlocked osteophytes in a 38-year-old female who had concurrent bilateral knee arthrosis. ⋯ Neither redislocation nor symptoms of instability was seen after 36 months of follow-up, although some progression of arthritis was observed. A new classification including all traumatic patellar dislocation was also proposed.

Primary stability of four different implants for opening wedge high tibial osteotomy.
Since a significant number of implant failures have been reported in association with the procedure of open wedge valgus high tibial osteotomy, the initial biomechanical stability of different fixation devices was investigated in this study. Fifteen third generation Sawbones composite tibiae were used as a model. Four different plates were tested: a short spacer plate (OWO) (n = 4), a short spacer plate with multi-directional locking bolts (MSO) (n = 5), a prototype version of a long spacer plate with multi-directional locking bolts (MSOnew) (n = 2), and a long medial tibia plate fixator with locking bolts (MPF) (n = 4). ⋯ The highest residual stability after failure of the lateral cortex was observed in MPF as well. The results suggest that the implant design strongly influences the primary stability of medial opening wedge tibial osteotomy. A rigid long plate fixator with angle-stable locking bolts yields the best results.

Two minimal incision fasciotomy for chronic exertional compartment syndrome of the lower leg.
Chronic exertional compartment syndrome (CECS) of the leg is a pathological condition often related to overuse in subject who engage repetitive physical activities. Fascial release is the mainstay of surgical management. The purpose of this study was to evaluate the results obtained with a double incision decompressive fasciotomy. ⋯ Two patients (18%) of the 11 who underwent to bilateral fasciotomy referred a sensation of leg weakness for an average period of 3 months. The surgical technique presented in this paper seems to be a good mean to treat anterior and lateral leg CECS. The use of tourniquet is deconselled to obtain an accurate intraoperative haemostasis so reducing the risk of post-operative haematoma.

Randomized Controlled TrialThe postoperative analgesic effects of intra-articular levobupivacaine in elective day-case arthroscopy of the knee: a prospective, randomized, double-blind clinical study.
Pain and emesis are the two major complaints after day surgery. Local anesthesia has become an important part of optimizing perioperative pain treatment. The aim of the present study was to study two different concentrations of levobupivacaine's effect on postoperative pain following elective arthroscopy of the knee with lidocaine 10 mg/ml with adrenaline as active control. ⋯ Level I: Prospective, randomized double-blind study without placebo.

Randomized Controlled TrialIntraarticular analgesia after arthroscopic knee surgery: comparison of neostigmine, clonidine, tenoxicam, morphine and bupivacaine.
We conducted a randomized, placebo-controlled, double blinded study to compare the analgesic effects of intraarticular neostigmine, morphine, tenoxicam, clonidine and bupivacaine in 150 patients undergoing arthroscopic knee surgery. General anaesthesia protocol was same in all patients. At the end of the surgical procedure, patients were randomized into six intraarticular groups equally. ⋯ Side effects were not significantly different among the six groups. We conclude that the most effective drugs that are administered intraarticularly are neostigmine and clonidine among the five drugs we studied. Tenoxicam provided longer analgesia when compared with morphine and bupivacaine, postoperatively.
