Context:Weight-bearing (WB) and non-weight-bearing (NWB) exercises are commonly used in rehabilitation programs for patients with anterior knee pain (AKP).Objective:To determine the immediate effects of isolated WB or NWB knee-extension exercises on quadriceps torque output and activation in individuals with AKP.Design:A single-blind randomized controlled trial.Setting:Laboratory.Participants:30 subjects with self-reported AKP.Interventions:Subjects performed a maximal voluntary isometric contraction (MVIC) of the quadriceps (knee at 90°). Maximal voluntary quadriceps activation was quantified using the central activation ratio (CAR): CAR = MVIC/(MVIC + superimposed burst torque). After baseline testing, subjects were randomized to 1 of 3 intervention groups: WB knee extension, NWB knee extension, or control. WB knee-extension exercise was performed as a sling-based exercise, and NWB knee-extension exercise was performed on the Biodex dynamometer. Exercises were performed in 3 sets of 5 repetitions at approximately 55% MVIC. Measurements were obtained at 4 times: baseline and immediately and 15 and 30 min postexercise.Main Outcome Measures:Quadriceps torque output (MVIC: N·m/Kg) and quadriceps activation (CAR).Results:No significant differences in the maximal voluntary quadriceps torque output (F2,27 = 0.592, P = .56) or activation (F2,27 = 0.069, P = .93) were observed among the 3 treatment groups.Conclusions:WB and NWB knee-extension exercises did not acutely change quadriceps torque output or activation. It may be necessary to perform exercises over a number of sessions and incorporate other disinhibitory interventions (eg, cryotherapy) to observe acute changes in quadriceps torque and activation.

Abstract Anterior knee pain is one of the main symptoms in osteoarthritis, resulting from the rich sensory innervation of its capsule. Pain control can be difficult to achieve, with non-responders to conservative and medical therapy often requiring a total knee replacement. Radiofrequency ablation (RFA) is a novel technique that could be beneficial in managing anterior knee pain by targeting the genicular nerves around the knee; however, its routine use is not included in current guidelines. A literature search identified fifty-two results, which underwent screening using a study protocol and the final literature sources, of varying levels of evidence, underwent critical appraisal and analysis. The primary outcome included the significant improvement of pain scores from baseline, against their respective control treatments. The ten studies included in the final analysis consisted of seven comparative studies and three non-comparative studies. Literature showed significant improvement in their mean pain scores, all meeting the primary outcome measure. Most studies also showed significant improvement from the control treatments used. Current literature shows evidence that genicular nerve RFA is an effective and safe treatment modality in the management of anterior knee pain secondary to osteoarthritis. However, the literature available is limited and further comparative studies are required.

Background: Anterior knee pain is a frequent condition after anterior cruciate ligament reconstruction (ACLR), but its origin remains uncertain. Studies have suggested that donor site morbidity in autologous bone–patellar tendon–bone reconstructions may contribute to patellofemoral pain, but this does not explain why hamstring tendon reconstructions may also present with anterior pain. Purpose: To evaluate the prevalence of anterior knee pain after ACLR and its predisposing factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated the records of all patients who underwent ACLR between 2000 and 2016 at a private facility. The prevalence of anterior knee pain after surgery was assessed, and possible risk factors (graft type, patient sex, surgical technique, range of motion) were evaluated. Results: The records of 438 patients (mean age, 30 years) who underwent ACLR were analyzed. Anterior knee pain was found in 6.2% of the patients. We found an increased prevalence of anterior knee pain with patellar tendon graft, with an odds ratio of 3.4 ( P = .011). Patients who experienced extension deficit in the postoperative period had an odds ratio of 5.3 of having anterior pain ( P < .001). Anterior knee pain was not correlated with patient sex or surgical technique. Conclusion: The chance of having anterior knee pain after ACLR was higher when patellar tendon autograft was used compared with hamstring tendon graft, as well as in patients who experienced extension deficit in the postoperative period.
