ReviewOutcomes of medial patellofemoral ligament reconstruction for patellar instability: a systematic review.
It has been suggested that in the majority of patellar dislocation cases the medial patellofemoral ligament (MPFL) is disrupted. Accordingly several authors over the past decade have recommended repair or reconstruction of the MPFL to reduce the high incidence of recurrent dislocation. The purpose of this review was to determine whether MPFL reconstruction is a suitable procedure with regards to clinical and radiological outcomes for patients with patellar instability. ⋯ When analysed, it would appear that MPFL reconstruction may provide favourable clinical and radiological outcomes for patellar instability patients. However, following a critical appraisal of these papers a number of methodological weaknesses were identified including recruiting small samples, not controlling for confounding variables, and providing limited statistical analysis of results. Future study is recommended to address these methodological flaws, in addition to beginning to assess the effectiveness of this procedure, in different patient groups.

Flexion gap preparation opens the extension gap in posterior cruciate ligament-retaining TKA.
It has been reported that preparation of the flexion gap results in significant widening of the prepared extension gap in posterior stabilized (PS) total knee arthroplasty (TKA). To date, there is a paucity of data regarding cruciate ligament-retaining (CR) TKA. Changes in the extension gap caused by preparation of the flexion gap were measured in 42 varus osteoarthritic knees undergoing CR TKA. ⋯ The extension gap increased significantly on both the medial and lateral sides (18.8-20.0 and 21.7-22.7 mm, respectively) (P < 0.01). Preparation of the flexion gap also resulted in significant widening of the extension gap on CR TKA. However, amount of extension gap increase in CR TKA was smaller than previous reports on PS TKA.

Controlled Clinical TrialLow back pain in young female gymnasts and the effect of specific segmental muscle control exercises of the lumbar spine: a prospective controlled intervention study.
Prospective controlled intervention study. To evaluate a specific segmental muscle training program of the lumbar spine in order to prevent and reduce low back pain in young female teamgym gymnasts. Teamgym is a team sport comprising three events: trampette, tumbling and floor programme. ⋯ Gymnasts in the control group showed no difference in terms of days with low back pain or intensity of low back pain between baseline and completion. Eight gymnasts (out of 15) with LBP in the intervention group became pain free. Specific segmental muscle control exercises of the lumbar spine may be of value in preventing and reducing low back pain in young teamgym gymnasts.

Traumatic knee extension deficit (the locked knee): can MRI reduce the need for arthroscopy?
In the present study we investigated the validity of magnetic resonance imaging (MRI) and arthroscopy in knees with acute, traumatic extension deficit (the "locked knee"), and evaluated whether arthroscopy of knees with no mechanical pathology could be avoided by MRI evaluation. The study consisted of 50 patients who had an acute, traumatic extension deficit of the knee. All patients were submitted to MRI prior to arthroscopy. ⋯ Assuming that arthroscopy was the gold standard, the following results were calculated for the overall appearance of a lesion able to cause locking: Positive predictive value = 0.85, negative predictive value = 0.77, sensitivity = 0.95, specificity = 0.53. Two knees were erroneously evaluated with no mechanical locking at MRI (one bucket-handle lesion and one pathological synovial plica). MRI of the knee with acute, traumatic extension deficit is in the acute or subacute phase a safe method to identify the patients that have a mechanical reason for locking and therefore can benefit from arthroscopic treatment.

Randomized Controlled TrialComparison of conservative treatment with and without manual physical therapy for patients with shoulder impingement syndrome: a prospective, randomized clinical trial.
The aim of this prospective, randomized clinical study was to compare the effectiveness of two physical therapy treatment approaches for impingement syndrome, either by joint and soft tissue mobilization techniques or by a self-training program. Thirty patients (Group 1, n = 15; Group 2, n = 15) with the diagnosis of an outlet impingement syndrome of the shoulder were treated either by strengthening the depressors of the humeral head with a guided self-training program (Group 1, age 49.5 +/- 7.9 years), or by joint and soft tissue mobilization techniques (Group 2, age 48.1 +/- 7.5 years). Group 1 was instructed with the active range of motion (ROM), stretching and strengthening exercise program including rotator cuff muscles, rhomboids, levator scapulae and serratus anterior with an elastic band at home at least seven times a week for 10-15 min and Group 2 received a prescription for 12 sessions of joint and soft tissue mobilization techniques, ice application, stretching and strengthening exercise programs and patient education in clinic for three times per week. ⋯ There were statistically differences among the groups in function (P > 0.05). Group 2 showed significantly greater improvements in the Neer Questionnaire score and shoulder satisfaction score than Group 1. The patients treated with manual physical therapy applied by experienced physical therapists combined with supervised exercise in a brief clinical trial showed improvement of symptoms including increasing strength, decreasing pain and improving function earlier than with exercise program.
