Workers' compensation (WC) status has been related to clinical outcomes; however, no comparative studies have been performed to assess 2-year outcomes between hip arthroscopy patients based on WC status. ⋯ Our study demonstrated that WC patients had significantly lower baseline PRO scores when compared with a matched-pair control group. However, both groups demonstrated statistically significant postoperative improvement in all scores. Patients with WC status started and ended with lower absolute scores but benefited from arthroscopic intervention for hip injuries. While patient and physician expectations may be adjusted accordingly, these results may reflect favorably on the use of hip arthroscopy for labral tears in the WC population.

Persistent pain and redislocations after surgical treatment of patellofemoral instability are described in up to 40% of patients. However, prospective outcome data about revision surgery are missing. ⋯ As patellofemoral instability is a multifactorial problem, revision surgery should be indicated only after a comprehensive examination. The results of this study show that MPFL reconstruction, alone or in combination, seems to be an effective treatment for recurrent patellar dislocations after a failed previous surgery, leading to significant increases in stability and functionality as well as a reduction in pain.

Comparative Study Clinical Trial
Psychometric properties of patient-reported outcome measures for hip arthroscopic surgery.
Patient-reported outcomes (PROs) are considered the gold standard when evaluating outcomes in a surgical population. While the psychometric properties of some PROs have been tested, the properties of newer PROs in patients undergoing hip arthroscopic surgery remain somewhat unknown. ⋯ The PROs of the HOOS and iHOT-33 demonstrate psychometric properties that may enable researchers and clinicians to use them with confidence in a population undergoing hip arthroscopic surgery. The psychometric properties of the MHHS, HOS, and some subscales of the HAGOS are reduced, and these PROs may be less valuable in this group.

Randomized Controlled Trial
Effect of prehabilitation on the outcome of anterior cruciate ligament reconstruction.
Prehabilitation is defined as preparing an individual to withstand a stressful event through enhancement of functional capacity. ⋯ The 6-week progressive prehabilitation program for subjects undergoing ACLR led to improved knee function based on the single-legged hop test and self-reported assessment using the modified Cincinnati score. These effects were sustained at 12 weeks postoperatively. This study supports prehabilitation as a consideration for patients awaiting ACLR; however, further studies are warranted.

In posterolateral corner (PLC) injuries in which the lateral collateral ligament (LCL) is intact, there is controversy about whether reconstructing the popliteus tendon (POP), the popliteofibular ligament (PFL), or both structures (POP + PFL) is required to restore normal external tibial rotation. ⋯ In an LCL-intact PLC injury model, the POP and PFL function as a unit in resisting external rotation. All surgical procedures described and tested were able to reduce the increased external rotational laxity found in the sectioned state. The PFL reconstruction technique was able to restore external rotation to near normal. However, the techniques involving POP reconstruction overconstrained external rotation during laxity testing.
