Questionnaires and physical tests are tools to determine the ability of an individual to perform tasks of the daily living. In our institution, a standardized knee performance evaluation including patient-reported outcome measures (PROMs) and physical performance tests has been applied to all patients undergoing total knee arthroplasty (TKA). Our goal was to identify which preoperative tools influence the outcomes of a TKA and if physical performance tests can be of value if used along with PROMs in predicting functional outcomes. Classification and regression tree was used to analyze which preoperative factors influence function after TKA. Western Ontario and McMaster Universities Arthritis Index (WOMAC) function (WOMAC-F), 6-minute walk test (6MWT), and timed up and go (TUG) test at the 12th postoperative month were the dependent variables. Age, body mass index, preoperative WOMAC function and pain score, muscle strength, 6MWT, and TUG test score were used as preoperative predictors of dependent variables. TUG ≤19.3 seconds and age <62 years were preoperative predictors of better scores in the WOMAC-F (5.5). Strength of extensor muscles of the nonoperated knee ≥99.43 N·m/kg and 6MWT> 328 m were preoperative predictors of a better postoperative 6MWT (499 m). TUG <12.3 seconds and 6MWT ≥421 m were preoperative predictors of better postoperative TUG (7.3 seconds). Preoperative performance in physical tests had an influence on postoperative outcome scores than PROMs after TKA. Less age, good muscular strength, greater capacity of walking, and smaller TUG times were associated with better outcomes.

The posterior cruciate ligament (PCL) is a fundamental structure in knee kinematics. PCL tears may lead to adverse consequences, such as impaired functional performance and an increased risk of osteoarthritis. Although surgical treatment is a well-established option for the patients of PCL rupture, many surgeons opt for conservative treatment because of the lack of consensus in the orthopedic literature concerning the best surgical method with less risk of iatrogenic lesions to the neurovascular structures in the popliteal region. Here, we describe an onlay technique for PCL reconstruction, which has some advantages over the traditional transtibial and over inlay techniques. The technique described in this study avoids the "killer angle"-frequently considered the cause of laxity of the reconstructed ligament-while simultaneously permitting safe retraction of the neurovascular structures without the need for a change in the patient's position. This technique has been used at our institution for approximately 10 years with very satisfactory results. The aim of this study is to describe the technique and perform a retrospective evaluation of the results of a case series.

The incidence of traumatic injuries of the upper limbs in a tertiary hospital has a wide variety. This is why the creation of a unified database becomes important-to know the patients' profile. Objective: This study sought to determine the profile of patients with traumatic injuries of the upper limbs, treated by Physical Therapy in Rehabilitation Center of the Clinics Hospital of Ribeirão Preto. Method: Two hundred and twenty-three patient records were evaluated (58 women and 116 men). They had an average age of 34.54 (± 19.05) years and were referred by the orthopedic clinic of this hospital. Results: Of the cases studied, wrist and hand injuries had the highest incidence (60.99%), followed by injuries of the shoulder (20.63%), elbow (12.55%), arm (3.59%) and forearm (2.24%). In injuries of wrist and hand, the trauma mechanism with the highest percentage was the motorcycle accident, associated with multiple handbone fractures. Falling down, motorcycle accidents, and falling off a ladder were the mechanisms of injury correlated with proximal humerus fractures, shoulder dislocations, and broken scapulas, respectively. Conclusion: The incidence of injury, trauma mechanism, and characteristics of the population was verified and further improvements in protocols for specific disorders and prevention can be made.

Objective:To evaluate the activity of wrist extensor muscle, correlating with wrist motion during gripping after flexor tendon repair.Design:Cross-sectional clinical measurement study.Setting:Laboratory for biomechanics and rehabilitation.Subjects:A total of 11 patients submitted to rehabilitation by early passive motion of the fingers with wrist flexion position were evaluated after 8 weeks of fingers flexor tendon repair and 11 healthy volunteers, all ranging from 20 to 37 years of age.Intervention:Volunteers performed an isometric standardized gripping task.Main measures:We used electrogoniometry to analyze wrist range of motion and surface electromyography, considering 100% maximum voluntary contraction to represent the amplitude of electromyographic activity of the extensor carpi radialis and flexor digitorum superficialis.Results:Patients with flexor tendon repair showed co-activation deficit between wrist extensor (extensor carpi radialis) and flexor finger muscles (flexor digitorum superficialis) during gripping in the intermediate phase of rehabilitation, despite some recovering mobility for wrist extension (p ≤ 0.05). A moderate correlation between range of motion and extensor carpi radialis was present only for injured group (r = 0.32). Total active motion score, which represents finger active excursion, was regular or poor in 65% of cases, all with nerve repair associated.Conclusion:Wrist extensors have an important synergist role at handgrip, although some imbalance can be present after flexor tendon repair. These preliminary findings suggest that emphasis could be directed to add synergistic wrist motion in rehabilitation protocols after flexor tendon repair. Future studies with early active rehabilitation are necessary.

Introduction. Gliding without adhesion is imperative to regain full range of motion after flexor tendon repair. The purpose of this study was to find assessment tools that represent these outcomes and to explore their relationship with hand function. Methods. Ninety-six flexor tendon injuries in 24 patients were assessed at 12 weeks after flexor tendon repair. Total active motion (TAM) and total passive motion (TPM) were recorded with a goniometer. For patientreported upper extremity function, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was used. Results. A moderate negative correlation was found between total active motion and DASH score (r ¼ 20.3809 to 20.5815, P , 0.0001). While TAM and TPM improved over the 12-week period, mean values did not reach those of the uninjured hand. Mean DASH scores improved from 46.05 points at four weeks to 23.5 points at 12 weeks. Conclusion. Despite early flexor tendon rehabilitation in this sample, after 12 weeks, some degree of dysfunction and loss of active ability for finger flexion still persisted. The DASH appears to be an appropriate outcome tool after flexor tendon repair. The combination of patient-reported questionnaire and measures of impairment such as TAM and TMP give a more comprehensive picture of functional outcome.
