Randomized Controlled TrialPlacement of a polyurethane implant is not associated with a chondroprotective effect: comparative study with cases of isolated medial meniscectomy with at least five years of follow-up.
Our main objective was to evaluate clinically and radiologically and compare patients who had undergone partial meniscectomy alone, with those who had received a partial meniscectomy in which a polyurethane implant was placed, with a minimum follow-up of 5 years. ⋯ II, therapeutic study.

Randomized Controlled TrialEffects of neuromuscular electrical muscle stimulation on the deltoid for shoulder function restoration after reverse total shoulder arthroplasty in the early recovery period: a prospective randomized study.
Neuromuscular electrical stimulation (NMES) is a treatment modality that has been used to accelerate the rehabilitation of patients with neurological damage. However, it is unclear whether NMES of the deltoid can lead to the early restoration of shoulder function after reverse total shoulder arthroplasty (RSA). ⋯ Postoperative NMES of the deltoid after RSA contributed to significantly faster ROM restoration and considerable improvement in the power of external rotation. Therefore, NMES following RSA could lead to the early restoration of external rotation and recovery of deltoid function.

Randomized Controlled Trial Multicenter StudyThe effects of tourniquet on cement penetration in total knee arthroplasty.
Aseptic loosening is a common cause of implant failure following total knee arthroplasty (TKA). Cement penetration depth is a known factor that determines an implant's "strength" and plays an important role in preventing aseptic loosening. Tourniquet use is thought to facilitate cement penetration, but its use has mixed reviews. The aim of this study was to compare cement penetration depth between tourniquet and tourniquet-less TKA patients. ⋯ Tourniquet use does not affect average penetration depth but increases the likelihood of achieving optimal cement penetration depth. Further study is warranted to determine whether this increased likelihood of optimal cement penetration depth yields lower revision rates.

Randomized Controlled TrialThe minimal clinically important difference (MCID) of the Olerud Molander Ankle Score (OMAS) in patients with unstable ankle fracture.
The Olerud Molander Ankle Score (OMAS) is a widely used validated Patient Reported Outcome Measure (PROM). For clinical research, it is important to determine the Minimal Clinically Important Difference (MCID). The objective of this study was to determine the MCID of the OMAS at several moments in the follow-up, in a cohort of patients that underwent open reduction and internal fixation of unstable ankle fractures with syndesmotic injury. ⋯ The calculated MCID in patients following surgery for unstable ankle fractures ranges from 10.5 to 15.0 at 3-6-month follow-up and from 7.5 to 11.4 at 6-12-month follow-up, depending on moment and method.

Randomized Controlled TrialComparison of three methods for sealing of the intramedullary femoral canal during total knee arthroplasty; a randomized controlled trial.
The purpose of this randomized controlled study was to examine the effect of sealing the intramedullary canal with a bone or cement plug or leaving it empty on postoperative bleeding and pain MATERIALS AND METHODS: A total of 120 patients with knee osteoarthritis who underwent unilateral TKA participated in the trial and were assigned to one of three groups. The femoral canal was sealed with an autogenous bone plug (Group I) or cement plug (Group II), or it was left open (Group III). Estimated blood loss, Hemoglobin decline, bleeding into the drain, and postoperative pain w compared between groups. ⋯ Level I, randomized controlled trial.
