Objectives: The objectives are to assess the results and to discuss the indications for Maquet osteotomy in patients with patellofemoral osteoarthritis. Methods: Retrospective study of a series of 32 patients (4 bilateral, that is to say, 36 knees) operated between March 1999 and October 2013 in " Arthroscopy Private Center ", 12 male and 20 female, average age 59 years with an average postoperative surgery outcomes of 53 months. The technique consists of an arthroscopic procedure to treat joint lesions and a tibial tuberosity osteotomy of 5 cm long, by embedding a 1cm subsequent graft taken from the same metaphysis and fixed with 2 screws. Results: All patients had significant improvement, evaluated with Kujala’s score (54 points preop to 86 points postop) and Guillamon Ferguson’s criteria (27.2 very good and 60.7 good). The complication rate was acceptable. Conclusion: The available technics are surgeries on proximal soft structures, osteotomies of tibial tuberosity and patellofemoral arthroplasty. Maquet osteotomy is an excellent procedure when the patient’s selection is right. Obtaining the graft from the same metaphysis simplified the procedure.

OBJECTIVE: We present our experience with an otoplasty technique that combines “closed” anterior scoring using the Stenström otoabrader with mattress sutures to the posterior cartilage. STUDY DESIGN AND SETTING: In a retrospective study, we report our experience with 135 patients operated on in the last 12 years. Some surgical principles make our procedure different from previous combination techniques: the posterior access incision is linear without skin excision; anterior scoring is performed along the entire antihelix and scapha, with care to score toward the concha at the tail of the antihelix to bring the ear lobe nearer to the mastoid; Mustarde's mattress sutures are used to stabilize the result. RESULTS: There were no major complications and few minor complications. The aesthetic results were graded as very good or good in 95% of the cases; the rest were graded as satisfactory. CONCLUSIONS: Our technique is versatile, gives pleasant, natural-looking results, and has a low complication rate. It is a simple, reliable, reproducible, and easily mastered method.

The purpose of this retrospective study was to report the occurrence of lateral patellar luxation in poodles. The animals were referred to the Orthopedics Service of the Veterinary Hospital, Faculdade de Ciências Agrárias e Veterinárias, - Jaboticabal Campus, São Paulo, Brazil, twelve client-owned poodles, seven females and five males poodles ranging in age from three to nine months. Clinical examination showed lameness, pain and deformities of the affected limbs. Surgical trochleoplasties were performed with medial retinacular overlap and medial tibial tuberosity transposition. The animals recovered their normal activity within a period of one to two weeks after surgery. Although this was a rarely occurring pathological condition in poodles, surgical repair was easy to execute because of its similarity to correction of medial patellar luxation. Lateral patellar luxation in small dogs is rare and, when present, is of congenital origin, at times progressing to marked functional impotence of the affected limbs.

Abstract BackgroundThe objective of present study was to investigate the operative effect of patellofemoral arthroplasty combined with the tibial tubercle transfer for isolated patellofemoral arthritis patients with an increased tibial tuberosity-trochlear groove distance (>20mm). MethodsA prospective study was performed between November 2012 and December 2017. Finally, thirty-six cases, with a mean age of 61.1 ± 7.3 years, were admitted to our study. A total of 17 patients underwent patellofemoral arthroplasty combined with tibial tubercle transfer, and 19 patients underwent patellofemoral arthroplasty only. All eligible patients had CT scans preoperatively and at 12 months follow-up, to assess the stability of the patellofemoral joint on axial slices. In addition, the demographic and clinical features of all the patients were asked. Knee balance was assessed with the single leg stance test and timed get up and go, and functionality was evaluated with stair climbing test and the Western Ontario and McMaster Universities Osteoarthritis Index score. (P>0.05) ResultsPreoperatively, the data regarding the knee balance and functionality were not significantly different between the two Groups (P>0.05). Many measurements showed significant differences between the two groups at the last follow-up. Significant differences were seen in well-known measurements such as the SLST (Group I, 28.9 s (SD 7.5); Group II, 20.3 s (SD 5.9); p < 0.001), TGUG (Group I, 13.4 s (SD 3.2); Group II, 16.8 s (SD 3.1); p < 0.001), and SCT (Group I, 18.6 s (SD 6.8); Group II, 24.5 s (SD 8.7); p < 0.001). Additionally, the median WOMAC score was improved from 62.7 (SD 11.2) preoperatively to 25.7 (SD 8.2) one year postoperatively in Group I and from 64.1 (SD 10.7) to 36.2 (SD 9.7) in Group II, which were also significantly different between the groups. ConclusionsFor such special IPA patients with an increased TT-TG (>20mm), the combined operation of PFA combined with TTT can better restore the involutional relationship of patellofemoral joint and further improve the balance and function of knee joint.

Identification and management of patients with isolated patellofemoral osteoarthritis are challenging. Many of these patients present at a young age and it is important to distinguish degenerative change in the patellofemoral articulation from the other various causes of anterior knee pain. Once the diagnosis of isolated patellofemoral arthrosis has been made non-operative and conservative surgical techniques should be exhausted fully before prosthetic arthroplasty is considered. This review focuses on the use of arthroplasty for isolated patellofemoral arthrosis, in particular comparing the use of total knee against selective patellofemoral joint replacements.

We report our experience over a 30 month period of endoscopic release of the carpal tunnel by the Chow two-portal technique. The objective of this retrospective study was to evaluate the long-term subjective results of surgery and to assess if any iatrogenic nerve injury had been caused by the endoscopic procedure. The follow-up period was from 3 to 34 months. Our permanent, iatrogenic, postoperative nerve complication rate was 0.9% (2/208). No other serious complications occurred.

Abstract Background: The optimal treatment of osteoporosis after reconstruction surgery for osteoporotic vertebral fractures (OVF) remains unclear. In this multicentre retrospective study, we investigated the effects of typically used agents for osteoporosis, namely, bisphosphonates (BP) and teriparatide (TP), on surgical results in patients with osteoporotic vertebral fractures. Methods: Retrospectively registered data were collected from 27 universities and affiliated hospitals in Japan. We compared the effects of BP vs TP on postoperative mechanical complication rates, implant-related reoperation rates, and clinical outcomes in patients who underwent posterior instrumented fusion for OVF and had been followed up at least for 2 years. Data were analysed according to whether the osteoporosis was primary or glucocorticoid-induced. Results: A total of 165 patients who underwent posterior instrumented fusion for OVF were included. The overall mechanical complication rate was significantly lower in the TP group than in the BP group (BP vs TP: 73.0% vs. 55.7%, p = 0.018). The screw backout rate was significantly lower and the rates of new vertebral fractures and pseudoarthrosis tended to be lower in the TP group than in the BP group. However, there were no significant differences in lumbar functional scores and visual analogue scale pain scores or in implant-related reoperation rates between the two groups. The incidence of pseudoarthrosis was significantly higher in patients with glucocorticoid-induced osteoporosis (GIOP) than in those with primary osteoporosis; however, the pseudoarthrosis rate was reduced by using TP. The use of TP also tended to reduce the overall mechanical complication rate in both primary osteoporosis and GIOP. Conclusions: The overall mechanical complication rate was lower in patients who received TP than in those who received a BP postoperatively, regardless of type of osteoporosis. The incidence of pseudoarthrosis was significantly higher in patients with GIOP, but the use of TP reduced the rate of pseudoarthrosis in GIOP patients.

Background: The new surgical procedure of full-endoscopic interlaminar lumbar discectomy (FILD) has achieved favorable effects in the treatment of lumbar disc herniation (LDH). Along with the wide range of applications of FILD, a series of complications related to the operation has gradually emerged. Objective: To describe the types, incidences, and characteristics of complications following FILD and to explore preventative and treatment measures. Study Design: Retrospective, observational study. Setting: A spine center affiliated with a large general hospital. Method: In total, 479 patients with LDH underwent FILDs that were performed by a single experienced spine surgeon between January 2010 and April 2013.Data concerning the complications were recorded. Results: All 479 cases successfully underwent the procedure. A total of 482 procedures were completed. The mean follow-up time was 44.3 months with a range of 24 to 60 months. The average patient age was 47.8 years with a range of 16 to 76 years. Twenty-nine (6.0%) related complications emerged, including 3 cases (0.6%) of incomplete decompression in which the symptoms gradually decreased following 3 – 6 weeks of conservative treatment, 2 cases (0.4%) of nerve root injury in which the patients recovered well following 1 – 3 months of neurotrophic drug and functional exercise treatment, 15 cases (3.1%) of paresthesia that gradually improved following 1 – 8 weeks of rehabilitation exercises and treatment with mecobalamin and pregabalin, and 9 cases of recurrent herniation (1.9%). The latter condition was controlled in 4 cases with a conservative method, and 5 of these cases underwent reoperations that included 3 traditional open surgeries and 2 FILDs. Furthermore, the complication rate for the first 100 cases was 18%. This rate decreased to 2.9% for cases 101 – 479. The incidence of L4-5 herniation (8.2%) was significantly greater than that of L5-S1 (4.5%). Limitations: This is a retrospective study, and some bias exists due to the single-center study design. Conclusion: FILD is a surgical approach that has a low complication rate. Incomplete decompression, nerve root injury, paresthesia, and recurrent herniation were observed in our study. Some effective measures can prevent and reduce the incidence of the complications including strict indications for surgery, a thorough action plan, and a high level of surgical skill.
