Comparison of knee loading in subjects 12 weeks post-anterior cruciate ligament reconstruction versus repair when performing a double-limb squat.

Background: Despite postoperative complications, anterior cruciate ligament reconstruction remains the gold standard treatment after a tear. Recent advancements in anterior cruciate ligament repair techniques have led to improved outcomes and renewed interest in repair as a less invasive alternative. The purpose of this study was to compare knee biomechanics and quadriceps strength during double-leg squat at 12 weeks between individuals who underwent anterior cruciate ligament reconstruction or repair.

Effects of Limb Dominance on Patellofemoral Joint Loading During Gait at 12 Weeks After Anterior Cruciate Ligament Reconstruction.

Background: Patellofemoral joint complications have commonly been reported in long-term outcome studies for anterior cruciate ligament reconstruction (ACLR); however, the biomechanics in the early phases of rehabilitation that could be associated with the development of these abnormalities is unclear. Limb dominance may affect the biomechanics of the knee joint in patients after ACLR.

Purpose: To compare knee joint loading between surgical and nonsurgical limbs at 12 weeks postoperatively in patients who underwent ACLR on either their dominant limb (ACL-D) or nondominant limb (ACL-ND).

The Iliofemoral Bounce Test: Identifying Hip Capsular Insufficiency.

Background: Insufficiency of hip capsular structures has recently gained recognition as a cause of pre-arthritic hip pain, leading to hip joint instability and progressive chondrolabral injury. An accurate evaluation of capsular integrity can help orthopedic surgeons plan capsular management prior to hip arthroscopy.

Indications: The proposed iliofemoral bounce test is meant to be applied preoperatively for identification of hip capsular integrity when microinstability is suspected or in the setting of revision hip arthroscopy.

Adolescent Athletes Demonstrate Inferior Objective Profiles at the Time of Return to Sport After ACLR Compared With Healthy Controls.

Background: Athletes display persistent muscle deficits and altered limb-loading mechanics at the time of return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR).

Purpose: To compare an objective profile of adolescent athletes at RTS after ACLR to matched healthy controls.

Study Design: Cross-sectional study; Level of evidence, 3.

Knee Loading After ACL-R Is Related to Quadriceps Strength and Knee Extension Differences Across the Continuum of Care.

Background: Quadriceps strength and knee extension are believed to be important in the ability to effectively load the knee after anterior cruciate ligament (ACL) reconstruction (ACL-R).

Purpose: To compare quadriceps strength (QUADS), side-to-side knee extension difference (ExtDiff), and knee energy absorption contribution (EAC) in patients preoperatively, 12 weeks postoperatively, and at return to sport (RTS). A secondary aim was to determine how the factors of QUADS and ExtDiff contributed to the ability to load the knee (knee EAC) at each of the 3 time points.

A Contact Pressure Analysis Comparing an All-Inside and Inside-Out Surgical Repair Technique for Bucket-Handle Medial Meniscus Tears.

Purpose: To directly compare effectiveness of the inside-out and all-inside medial meniscal repair techniques in restoring native contact area and contact pressure across the medial tibial plateau at multiple knee flexion angles.

Methods: Twelve male, nonpaired (n = 12), fresh-frozen human cadaveric knees underwent a series of 5 consecutive states: (1) intact medial meniscus, (2) MCL tear and repair, (3) simulated bucket-handle longitudinal tear of the medial meniscus, (4) inside-out meniscal repair, and (5) all-inside meniscal repair. Knees were loaded with a 1,000-N axial compressive force at 5 knee flexion angles (0°, 30°, 45°, 60°, 90°), and contact area, mean contact pressure, and peak contact pressure were calculated using thin film pressure sensors.

The use of a pitch count estimator to calculate exposure in collegiate baseball pitchers.

Objective: Excessive pitch counts have been associated with arm pain in pitchers. Tracking of exposure is difficult based on participation on multiple teams and variability in organizational rules. Statisticians have estimated exposure for professional pitchers using pitch count estimators.

Meniscus suture repair: minimum 10-year outcomes in patients younger than 40 years compared with patients 40 and older.

Background: Few studies have compared outcomes after meniscus suture repair in patients younger than 40 years versus patients 40 years and older.

Purpose: To document failure rates and long-term outcomes after meniscus suture repair by a single surgeon, using the inside-out technique, at a minimum 10-year follow-up in patients younger than 40 years versus those 40 years and older.

Study Design: Cohort study; Level of evidence, 3.

Arthroscopic suture bridge transosseus equivalent fixation of rotator cuff tendon preserves intratendinous blood flow at the time of initial fixation.

Background: Current etiologic theories concerning healing rates in rotator cuff repair have focused on the blood supply in the tendinous portion of the cuff. We currently have little information regarding the effect of our repair techniques on this critical variable. We hypothesize that intratendinous blood flow is changed during transosseus equivalent tendon fixation.

A comparison of forearm supination and elbow flexion strength in patients with long head of the biceps tenotomy or tenodesis.

Purpose: The purpose of this study was to compare the forearm supination and elbow flexion strength of the upper extremity in patients who have had an arthroscopic long head of the biceps tendon (LHBT) release with patients who have had an LHBT tenodesis.

Methods: Cybex isokinetic strength testing (Cybex Division of Lumex, Ronkonkoma, NY) was performed on 17 patients who underwent arthroscopic LHBT tenotomy, 19 patients who underwent arthroscopic LHBT tenodesis, and 31 age-, gender-, and body mass index-matched control subjects. Subjects were considered fully recovered from shoulder surgery, were released for unrestricted activities, and were at least 6 months after surgery before testing.

Long head of the biceps tendon pain: differential diagnosis and treatment.

Unlabelled: Though the role of the long head of the biceps tendon (LHBT) in shoulder pathology has been extensively investigated, it remains controversial. Historically, there have been large shifts in opinions on LHBT function, ranging from being a vestigial structure to playing a critical role in shoulder stability. Today, despite incomplete understanding of its clinical or biomechanical involvement, most investigators would agree that LHBT pathology can be a significant cause of anterior shoulder pain.

Surgical and therapeutic management of a complete proximal hamstring avulsion after failed conservative approach.

Study Design: Case report.

Background: After 2 attempts at conservative care for a diagnosis of hamstring strain, the patient had a surgical hamstring allograft reconstruction. The purpose of this report is to describe the physical therapy approach to postoperative management of a hamstring reconstruction.

Rehabilitation after arthroscopy of an acetabular labral tear.

Over the past few years, arthroscopy of the hip joint is becoming more common as a technique in both the diagnosis and treatment of hip pain. A frequent cause of hip and groin pain is a tear of the acetabular labrum. Patients with labral tears complain of pain in the groin region and pain with clicking in the hip without a history of pain prior to the original onset.

PLRI: posterolateral rotatory instability of the elbow.

Recurrent and persistent instability of the elbow has long been a source of confusion and dismay for both patients and physicians. Early recognition after elbow injury and careful attention to soft tissue repair during lateral elbow surgery may diminish the incidence of this condition. Repair and reconstruction of the lateral ulnar collateral ligament (LUCL) now offers practical and often successful solutions for patients with posterolateral rotatory instability (PLRI) of the elbow.
