Percutaneous and minimally invasive surgery is one of the greatest advances in the operating field of orthopedic since the late 1990s. The potential advantages include a shorter operative time, quicker recovery, and reduced hospital stay compared with traditional open surgery. However, scientific validation of the safety and efficacy of hallux valgus (HV) percutaneous surgery remains inconclusive. The objective of the present study was to systematically review the published data and clinical evidence for percutaneous HV surgery, evaluate the scientific method of the reports, and clarify the indications, safety, efficacy, and potential risks of these surgical techniques. Two reviewers independently identified the studies using a PubMed search, with the keywords "hallux valgus," "osteotomy," "minimally invasive," and "percutaneous." Quality assessment was performed using the Coleman methodology scale, and each study was assigned a level of evidence and grade of recommendation. Eighteen studies were included and reported a total of 1534 procedures for percutaneous HV surgery on 1397 patients. Of the 18 studies, 14 (77.8%) were level IV, 2 (11.1%) were level III, and 2 (11.1%) were level II. Overall, the average angle correction of the HV deformity improved postoperatively. Regarding the complications, although some investigators revealed no major complications, others described deformity recurrence in 7.8%, stiffness of the first metatarsophalangeal joint in 9.8%, malunion in 4% to 8.7%, and infection rates ranging from 1.9% to 14.3%. The main indication for percutaneous HV surgery is the correction of mild deformities. The complication rate was elevated even in experienced surgeons. In conclusion, future research in percutaneous techniques should include adequately sized randomized control trials, standardization of treatment protocols, and the use of validated tools for the measurement of clinical outcomes.

Non-anatomic, mobile-bearing, hydroxyapatite-coated and non tibial-stemmed total ankle replacements are positively associated with more periprosthetic bone cysts.

Arthroscopic release of the FHL tendon was a valid procedure. It was a minimally invasive surgery that allowed good visualization of the involved structures and yielded good results. This condition can be related to trauma and is not an exclusive disease of ballet dancers or overuse.

PurposeRupture of the Achilles tendon (AT) is a common injury. Strength deficits may persist over the long term, possibly owing to elongation of the tendon or inferior mechanical properties. This study aimed to provide a systematic review of the literature on the prevalence and consequences of tendon elongation in patients after acute AT rupture treatment. It was hypothesized that an elongated tendon would be associated with a worse clinical outcome. MethodsThe databases for MEDLINE, CENTRAL and Web of Science were searched. Clinical studies related to AT rupture reporting tendon elongation and clinical or functional outcomes, with a minimum follow‐up of 6 months, were eligible for inclusion. Only studies testing for statistical correlations (SCs) between AT elongation and other outcomes were eligible, with the exception of biomechanical studies in which statistically significant AT elongation was found to be a generalized finding in the study group. For these studies to be eligible, the study group had to be compared with a healthy control group, or the injured limb compared with the uninjured limb, regarding biomechanical parameters. ResultsTwenty‐eight papers were selected for inclusion. Mean AT elongation measured with imaging techniques ranged from 0.15 to 3.1 cm (n = 17). Ten studies investigated SCs with Patient Reported Outcome Measures (PROMs), in which two found SCs with tendon elongation. Five studies reported strength and power evaluations and their correlation with AT elongation, with two having found SCs between decreased strength and tendon elongation. In ten studies reporting data on biomechanical tests, nine found influence of tendon elongation. In this group, four out of five studies found SCs with biomechanical parameters. ConclusionFair evidence of the influence of tendon elongation in biomechanical parameters was found. In a general population, evidence of a detrimental effect of tendon elongation on PROMs or functional strength at follow‐up was not found in this review. Level of evidenceLevel IV.

This study indicates that the repair of the proximal tibiofibular joint with a transarticular bicortical suspension device tensioned to 40 and 50 N can restore the normal kinematics of this joint. Based on these findings, Surgeons may consider this option as a reliable solution when planning successful treatment for proximal tibiofemoral joint instability.
