INTRODUCTION: The aim of this study has been to present outcomes after cementless arthroplasty for developmental dysplasia Crowe type IV of the hip, with transverse subtrochanteric shortening osteotomy and using the S-ROM stem. METHODS: We evaluated radiographs, functional scores and complications in a consecutive series of 23 patients (28 hips) with high dislocation of the hip. The average age of patients at surgery was 49.9 (range 22-68) years. The operations were performed between 2007 and 2013. Patients were assessed retrospectively-clinically and radiographically during the year 2018. RESULTS: The mean follow-up period was 94 (range 60-134) months. The average Harris hip score improved from 39.9 to 84.0. The mean leg length discrepancy decreased from 5 cm preoperatively to 1.4 cm at the final follow-up. All acetabular components were implanted into the true acetabulum, and all prostheses were stable at the latest examination. No neurovascular damage was recorded. We have identified specific complications in seven hips (25%) in total: Intraoperative femoral fracture required fixation in four hips; three hips (10.7%) needed revision: Recurrent dislocation, with the need for cup reorientation, occurred in two hips (in one of them, this was followed by the subsequent need for resection of heterotopic ossification); there was one aseptic stem loosening with the need of one-stage revision. All the osteotomies healed within 8 months. CONCLUSION: Hip arthroplasty with transverse shortening femoral osteotomy, using S-ROM stem, is an acceptable, but not complication-free treatment method in patients with Crowe type IV developmental hip dysplasia, in the midterm.

V našej práci prezentujeme kazuistiku 44ročného pacienta so spontánnou bilaterálnou ruptúrou proximálnej časti ligamentum patellae. U pacienta neboli zistené systémové ochorenia ako rizikové faktory šľachových ruptúr. Diagnóza bilaterálnej ruptúry bola potvrdená fyzikálnym vyšetrením a RTG nálezom (patella alta). Druhý deň po úraze bola u pacienta realizovaná bilaterálna reinzercia ruptúr transoseálnymi stehmi cez tunely v patele spolu s odľahčením sutúry serklážnymi slučkami. Vzhľadom k re-ruptúre na pravom kolene po dvoch týždňoch od sutúry bola realizovaná revízna operácia - reinzercia šľachy pôvodnou metódou a augmentáciou šľachami musculus semitendinosus a musculus gracilis. Pooperačne boli obidve kolená fixované v ortézach po dobu 12 týždňov, flexia do 60° bola pacientovi povolená po 6 týždňoch a flexia nad 90° po 9 týždňoch. Po jednom roku od úrazu mal pacient aktívne bilaterálne plnú extenziu. Rozsah flexie v pravom kolene bol 125° a vľavo 130°. Subjektívne pociťoval pacient pravé koleno ako stabilnejšie. Klinický výsledok operačnej liečby bilaterálnej ruptúry ligamentum patellae závisí od skorej operačnej intervencie a pooperačnej rehabilitácie. V prípade re-ruptúr, sutúr s časovým odstupom a v prípadoch nedostatočnej kvality šľachy je indikovaná augmentácia šľachy autológnym štepom, alogénnym štepom alebo syntetickými materiálmi. Podobný prípad sme v slovenskej ani českej literatúre zatiaľ popísaný nenašli.

We present the case of a 44-year-old patient with spontaneous bilateral ruptures of the proximal part of the patellar ligament. There were no identified specific risk factors for tendon ruptures. The diagnosis of bilateral patellar tendon rupture was confirmed in the initial physical examination with unambiguous x-ray diagnosis of patella alta. The second day after the injury, the patient underwent bilateral reinsertion of the rupture with transosseous suture (FiberWire) through tunnels in patella, together with the protection of the primary repairs using cerclage wires. Due to re-rupture of the patella ligament of the right knee two weeks later, revision procedure was carried out. That consisted of resuture of the tendon by the original method and augmentation using the semitendinosus and gracilis tendons. Postoperatively, both knees were fixed in orthoses for 12 weeks, flexion to 60° was allowed after 6 weeks, and flexion beyond 90° after 9 weeks. After one year from injury, the patient had an active bilateral full extension. The range of the right knee flexion was 125° and 130° on the left. The range of the right knee flexion was 125° and 130° on the left. The patient subjectively felt his right knee to be more stable. The clinical results of surgical treatment of the bilateral rupture ligamentum patellae tendons depend on early surgical intervention and post-operative rehabilitation. Augmentation of the tendon with autograft, allograft, or synthetic materials is indicated in the case of re-ruptures, late sutures and in cases of deficient quality of the tendon. We found no similar case described either in the Slovak or Czech literature.

PURPOSE OF THE STUDY Evaluation of short-term functional results in patients undergoing one-stage surgery involving sequential bilateral total knee arthroplasty (TKA) and comparison with the results of patients after unilateral TKA. MATERIAL AND METHODS The group with bilateral TKA consisted of 171 patients with 342 total knee replacements treated between 2009 and 2013. The control group included 50 patients with 50 TKAs operated on in the years 2010 to 2012. The indications to bilateral knee replacement included bilateral gonarthrosis, grade III or more in patients who were in good health and had a stable knee joint with axis deviation up to 20 degrees. A cemented TKA was used and the posterior cruciate ligament was preserved. Assessment of functional results was based on the Womac score, Knee Society Score (KSS 1, 2) range of motion and presence of specific complications in both groups. The follow-up lasted three years. RESULTS The average results in the bilateral vs the control group were as follows: the Womac score, 39.4/42.2 pre-operatively, 87.2/71.0 at 3 years; KSS 1, 48.5 / 44.8 pre-operatively, 87.4 / 79.9 at 3 years; KSS 2, 44.1 / 50.6 pre-operatively, 86.1 / 72.8 at 3 years; motion-flexion, 105.2° / 105.7° preoperatively, 114.0° / 100.2° at 3 years. In the bilateral group, infection was recorded in one patient. DISCUSSION Bilateral total knee replacement is a controversial issue. A higher risk of non-specific complications has been reported. Functional outcomes are good. The key problem is to set the correct indication to this procedure after an individual assessment of the patient's general health condition and the state of his/her knee joints. CONCLUSIONS The patients undergoing bilateral TKA at one-stage surgery showed functional results comparable (range of motion was even better) with the results of the unilateral TKA group. The number of specific complications was low. Every patient should be carefully assessed. Key words: total knee arthroplasty, bilateral implantation, functional results.
