This study aims to analyze the functional outcomes and lateral knee stability of patients who underwent lateral collateral ligament (LCL) and biceps femoris tendon reconstruction with suture anchors after proximal fibula en bloc resection for bone tumors. Patients who underwent proximal fibular en bloc resection between 2007 and 2018 were retrospectively viewed. Patients were invited to visit the clinic, and their functional scores were evaluated using the Musculoskeletal Tumor Society Scoring (MSTS) system. Lateral knee stability was evaluated by varus stress radiographs obtained at 20 degrees of flexion, and the range of motion (ROM) of the bilateral knee was assessed. Side-to-side differences were graded according to the International Knee Documentation Committee (IKDC) criteria and compared between types I and II resections. A total of 17 patients (4 males and 13 females) with a mean age of 31.1 ± 17.1 (range: 13–65) years at the time of surgery were available for radiological and clinical examination at a mean follow-up of 68.6 ± 36.4 (range: 22–124) months after surgery. In terms of ROM measurements, IKDC grades and side-to-side differences in both flexion and extension were not significantly different between the groups. On varus stress radiographs, lateral knee gapping was measured to be 0.93 ± 0.91 mm in type-I resections and 1.83 ± 0.45 mm in type-II resections, and statistically significant differences were detected among the groups (p = 0.039). When the values were graded according to IKDC criteria, none of the knees were classified as abnormal, and no difference was observed between the groups. Mean MSTS score of patients with type-I resections was significantly higher than those of patients with type-II resections (92.7 vs. 84.4%, p = 0.021). In the subscale analysis, a significant difference was observed in the support scores (type I = 94.5%, type II = 70%; p = 0.001). The reattachment of LCL and biceps femoris tendon to the tibial metaphysis with a suture anchor is a simple and effective method to prevent lateral knee instability after proximal fibula resections.

Türk Ortopedi ve Travmatoloji Birliği Derneği kompartmandan iletilmekte ve kıkırdak, subkondral kemik ve medial menisküste anormal bir strese neden olmaktadır. [2] Genelde medialden başlayan diz osteoartriti adeta bir kısır döngü halinde eklemin tamamına yayılmaktadır. Yüksek tibial osteotomi (YTO) ise bu kısır döngüyü, yükü lateral kompartmana kaydırarak kırma şansına sahiptir. Böylelikle dejenerasyonun önüne geçilmeye çalışılır. [3] YTO'nun temel olarak üç yöntemi vardır;• Kapalı kama,• Açık kama,• Kubbe yani "dome" osteotomisi. [4] A lt ekstremite mekanik aksı (ekseni), diz ekleminin kıkırdak yüzeylerinin aşınma durumu için önemlidir. Tarihsel süreçte diz çevresi osteotomileri, özellikle unikompartmantal diz osteoartritinin tedavi yöntemlerinden biri olmuştur. Fakat artroplastideki güncel gelişmeler ve yeni implantlar, osteotomiye olan ilgiyi azaltmaktaydı. Son yıllarda eklemin doğal durumunu korumak, gelecekteki olası artroplasti seçeneğini geciktirmek veya önlemek amacıyla unikompartmantal kondral patolojisi ve mekanik uyumsuzluğu olan genç hastalarda diz çevresi osteotomilerine olan ilgi tekrar artmıştır. Dizde varus deformitesi, osteoartritte en sık görülen mekanik dizilim bozukluğudur.
