Analyses of Timing of Single Heel Raise and Muscle Power after Achilles Tendon Repair / 대한정형외과학회잡지

PURPOSE: The purpose of this study is to analyze the progress of muscle rehabilitation for patients with acute Achilles tendon rupture, who underwent Achilles tendon repair, checking capable time of single heel raise and isokinetic plantar flexion power. MATERIALS AND METHODS: From March 2006 to June 2011, 42 of 81 patients were excluded and the other 39 patients, who underwent surgery due to acute Achilles tendon rupture in our institute, were enrolled in this study. The operation and rehabilitation were constantly performed according to the author's method. Isokinetic plantar flexion power was measured at three months post-operation, capable time of single heel raise was assessed, and clinical results of the last follow up were measured and analyzed. RESULTS: Single heel raise was possible at an average of 14 weeks and three days, and repetitive single heel raise more than 10 times was possible at an average of 20 weeks. The peak torque of 30degrees/s plantar flexion was mean 69 Nm. The peak torque of 120degrees/s was 41 Nm. Assessment at three months post-operation showed 69% power, compared to the contralateral leg. The group of patients who were able to perform single heel raise within three months, showed better Achilles tendon total rupture score and foot and ankle outcome score at last follow up, and showed better plantar flexion power at three months post-operation. CONCLUSION: At the last follow up, we can expect better clinical results and muscle power in patients who are able to perform single heel raise early treatment of acute Achilles tendon rupture.

Treatment of Talonavicular Subluxation Accompanied by Calcaneal Malunion: A Case Report / 대한족부족관절학회지

There may be complications after comminuted or intraarticular calcaneal fracture regardless of the initial treatment. Transcalcaneal talonavicular dislocation is rarely reported severe form of calcaneal fracture. We experienced a neglected transcalcaneal talonavicular subluxation case, who had been treated for intraarticular calcaneal fracture conservatively. Subtalar distraction bone block fusion was done for calcaneal malunion with talonavicular subluxation. Inspite of successful subtalar fusion, pain was persisted because of talonavicular re-subluxation with arthritis and calcaneocuboid arthritis. So, second operation, the talonavicular and calcaneocuboid fusion, was done. After union achieved, the patient's foot pain was improved. Calcaneal malunion combined with talonavicular subluxation and unstable transverse tarsal joint, such as this case, initial triple arthrodesis could be considered.

A Case of Delayed Recurrent Hemarthrosis after Percutaneous Pin Fixation of the Patellar Fracture

A 24-year-old man underwent percutaneous fixation with pins for an undisplaced patellar fracture. At 7 months follow-up postoperatively, he presented with recurrent, painful swelling of the operated knee following trivial activities of daily life. Aspiration had been performed two times before he presented to us with symptoms. An x-ray showed that one of the pins was suspected to be protruding at the inferior pole of the patella. Magnetic resonance imaging confirmed effusion in the joint. Arthroscopy revealed that the pin was prominent intraarticularly, and the adjacent infrapatellar fat pad with surrounding synovial tissue seemed to be abraded. The pins were removed under arthroscopic guidance and any pain or hemarthrosis disappeared thereafter.
