Is Single Puncture Superior to Double Puncture Arthrocentesis in Patients With Wilkes III Internal Derangement?

Abstract

BACKGROUND:

Arthrocentesis is a minimally invasive procedure with reported efficacy when used for lysis and lavage of the joint for symptomatic internal derangement, irrespective of the technique utilized.

PURPOSE:

The purpose of the study was to determine if the single puncture arthrocentesis (SPA) is superior to double puncture arthrocentesis (DPA) with respect to pain reduction and improved maximal mouth opening (MMO) for subjects with acute disc displacement without reduction.

STUDY DESIGN AND SETTING:

A single-blinded randomized prospective clinical trial was conducted at the tertiary referral center for temporomandibular joint disorders. All subjects were diagnosed with acute onset disc displacement without reduction based on history and magnetic resonance imaging findings. Subjects were randomized to SPA or DPA.

PREDICTOR VARIABLE(S):

The primary predictor variable was arthrocentesis technique (SPA vs DPA).

MAIN OUTCOME VARIABLE(S):

The primary outcome variables were pain and MMO, measured at 4 weeks. The duration for the procedure was recorded at the time of the surgery.

COVARIATES:

Age, sex, and the side affected were recorded.

ANALYSES:

Data were analyzed using analysis of variance to compare the primary outcome variables. Levene's, post hoc, and Bonferroni-Holm tests were used for intergroup comparisons with a P value of <0.05 being significant.

RESULTS:

Forty subjects completed the study. The mean age for the SPA and DPA groups was 28.3 (±3.9) and 29.1 (±4.1), respectively (P = .52). The sex distribution was 60 and 55% female in the SPA and DPA groups, respectively. The mean pain reduction in the SPA and DPA groups was from 8.30 (±0.86) to 0.90 (±0.78) and from 8.00 (±0.79) to 0.95 (±0.82), respectively (P < .0001). There was no difference in pain reduction between the groups (P = .05). The mean increase in MMO was 34.6 (±2.34) and 33.4 (±2.35) in the SPA and DPA groups, respectively (P < .0001). The difference between the groups was not significant (P = .12). The procedural time in the SPA and DPA groups was 14.15 ± 1.72 and 17.55 ± 1.66, respectively (P < .0001).

CONCLUSION:

SPA and DPA arthrocentesis appear to be equally efficacious for pain reduction and increasing MMO. SPA can be completed in less time than DPA and should be considered as a viable alternative to the conventional DPA technique.
